SPECIFICATIONS

General remarks

CONNECT Nav + (from now on referred to as N.I.T. for simplicity) consists of an electronic control unit located in the middle of the facia. This includes information, communication, audio/video and climate control system programming functions (for a description of climate control functions).

Il CONNECT Nav +. is equipped with a front panel connected to the main electronic unit. This includes a multifunction display and a series of control buttons used to activate the individual functions.

CONNECT Nav + allows a more rational approach to vehicle controls. It allows the driver a more relaxed drive and makes it easier to operate the controls.

The system is fitted in the middle of the facia and may be used easily by the driver and passenger. It includes the following systems/services:

• radio, with tape player and CD player/changer;
• TV tuner;
• trip computer;
• check control display;
• GSM radio phone wiht voice recognition module;
• voice mail
• navigation system.
• vehicle set-up (door open/close programming, seat position adjustment/store, supplementary heater system programming, parking brake mechanism etc.)

• 1 Connect module
• 2 Speakers
• 3 GPS/GSM aerial
• 4 Steering wheel controls (opt)
• 5 CDC (opt)
• 6 BOSE subwoofer (opt)
• 7 Handsfree microphone
• 8 AUDIO amplifier
• 9 Radio/TV aerials

The Info Telematic Node manages the following tasks:

• receives and sends information on the B-CAN line (e.g.: diagnosis, warning lights, controls, data)
• adds commands for interaction with the various menus
• manages a high definition colour display for navigation or TV
• connects with facia wiring for connection to the vehicle electrical system
• connects with communications wiring for point/point connection of TV tuner, rear TV camera, video cassette player
• set-up for connection with components such as DVD, rear multivideo screens etc.
• interfaces with GPS, GSM and radio aerials by means of coaxial leads

The infotelematic node features a thermal protection function that restricts its operation as internal temperature increases. This prevents permanent damage to the system.

The system is fully operational for interior temperatures lower than 85 °C.

Because normal system operation gives rise to a temperature increase of 20 °C despite a cooling fan in the rear of the NIT, the system interior reaches a limit temperature that leads to deactivation with a passenger compartment temperature of about 65 °C.

Self-diagnosis

The system comes with a self-diagnostic function that checks whether the NIT unit is correctly connected to all external components.

Access to self-diagnostic mode is achieved by pressing the "MAIN" button (1) for at least 10 seconds.

The following components/signals can be diagnosed by means of this function:

• External signal amplifier
• "Coolant level low" signal [F010]
• "Window washer level low" signal [F011]
• +15 signal [F040]
• Exterior lighting sensor activation level signal [F044]
• NIT buttons [F153]
• CD changer [F156]
• Microphone [F160]
• Aerial, phone module and SIM GSM card reader [F166]
• TV tuner and aerial series [F172]
• GPS receiver and aerial [F174]
• CD reader and navigation CD [F174]
• Telephone handset
• Speakers
• Infrared remote control (IR)
• Radio aerial

EOL test mode is used to check whether the NIT unit has been connected to all exterior components following system installation on the vehicle.

It is not therefore necessary to carry out an operation test on the finished system.

Entering test mode

Press the MAIN button for at least 10 seconds to enter EOL test mode.

Two different test modes may be selected on the main test mode page.

The menu opens at the status page, i.e. the first menu item, upon access to EOL test mode.

Exiting test mode

The system returns to normal mode if no test page is selected for 10 seconds.

Test mode is also abandoned if vehicle speed exceeds 7 km/h.

If vehicle speed is lower than this threshold, test mode may be abandoned only from the main diagnosis page. This is done by pressing the exit button or waiting for the time period mentioned previously to elapse.

Visual representation of test results

In test mode, these take the form of a limited number of instructions in text format.

Positive or negative test outcomes are indicated by means of colour (green or red).

Symbols for tests that may not or must not be carried out yet (e.g. button test) are indicated in yellow.

Tests that cannot be carried out automatically (e.g. TV tuner) must be confirmed manually.

The person who carries out the tests must press the "passed" or "failed" test button in this case.

Storing test results

Test results must be stored in a non-volatile memory so that they can be read by the tester at a later stage.

Test mode exit date and time are also stored if valid date and time data are available and at least one test procedure has been carried out in the current test mode cycle.

Display impementation

In test mode, the display may not be turned on or off on the basis of ignition key position.

Status page

The status page displays all tests that may be carried out automatically. It also shows signal status depending on exterior component availability. e.g. CD changer, TV tuner, telecommunications unit.

External signal amplifier

The status page shows feedback signal status. This indicates whether the car is fitted with a low or high range sound system (BOSE).

Coolant level too low signal [F010]

The status page displays a "low coolant level" signal status, that is transferred from the interface processor to the main processor.

Screen washer fluid level too low signal [F011]

The status page displays a "low screeen washer fluid level" signal status, that is transferred from the interface processor to the main processor.

+15 signal [F040]

The status page displays ignition signal status. The display and background lighting cannot be deactivated when the signal is turned off.

Exterior light sensor activation level signal [F044]

The status page displays selected activation level in the form of a number of steps (1, 2, 3) and measured voltage level. This is transferred from the interface processor to the main processor.

NIT buttons [F153]

This test can be used to test all hard buttons and the two rotary knows on the NIT unit

To simplify the test, a button test page on the display displays button and rotary knob symbols.

If these buttons pass the manual depression or rotation tests successfully, the symbol colour changes from yellow to green to indicate the function is OK.

If the buttons and knobs are not all detected within 30 seconds, the undetected buttons are marked as defective (in red).

The connection between NIT and CCA units passes the test if it is possible to enter test mode.

CD changer [F156]

The test status page indicates whether a CD changer is available and whether the test CD inserted can be accessed.

To test connection L, the first sound track of the inserted CD is played when the soft "play" button is pressed.

Microphone [F160]

The microphone function is tested by recording a short utterance of 4 seconds maximum duration and playing it back after a short pause.

While the test utterance is recorded, the person carrying out the test must keep the soft button depressed.

If maximum recording time is exceeded, the recording will stop.

Playback begins shortly after the recording button has been pressed.

Aerial, phone module and SIM GSM card reader [F166]

The aerial, phone module and SIM GSM card reader are checked jointly by carrying out a recording test with a GSM network. A SIM card must be inserted in the card reader before the test begins.

If the SIM card reader cannot access the SIM card, the SIM card test is recorded as a failure. The symbol colour changes from yellow to red. The same thing happens if it cannot log onto the GSM network within 60 seconds.

GPS receiver and aerial [F174]

The status page displays the GPS aerial connection. An error message is displayed if the main processor cannot access a GPS receiver.

CD Player and navigations CDs [F174]

The NIT unit attempts to read some files on the CD containing the navigation database. The result indicates whether access to the CD play and data files was successful.

Insert navigation CD before starting this test.

Telephone handset

To carry out this test, lift the phone handset and then press some number keys and the "call set" button.

This call request is suppressed in diagnosis mode. The screen displays phone handset status (replaced or lifted) and the number dialled.

Phone handset cable LF line status can be checked only by attempting to make a phone call through the handset.

It is not possible to switch the phone handset microphone directly to the audio amplifier.

Simple connection test:

• the connection between phone handset and NIT unit can be checked by lifting the phone handset, i.e. taking it off the hook;
• phone handset status is indicated on the display.

Speakers

Check the coils of all connected speakers to run a full check on the sound system speakers.

Both sound systems come with 4 corner speakers and 1 subwoofer.

The top-of-the-range sound system also comes with a central speaker.

In the case of the bottom-of-the-range amplifier, this test requires a sequence of 9 steps, i.e. 4 x (tweeter + midwoofer) + 1 x subwoofer.

In the case of the top-of-the-range amplifier, this test requires a sequence of 10 steps, i.e. 4 x (tweeter + midwoofer) + 1 x subwoofer + 1 x central speaker.

Corner speakers:

• the tweeter test is carried out at 10 kHz.
• the midwoofer test is carried out at 500 kHz.

Subwoofer:

• the test is carried out by simultaneous application of 80 Hz to all 4 channels.

Central speaker:

• the test is carried out by simultaneous application of 1500 Hz to the two front channels.

The tested coil is indicated on the display. If the test signal is not audible, the person carrying out the test must press a soft button with the indication "Error".

The relevant coil symbol will go red. Otherwise it must go green.

Test signal amplitude is programmed by the NIT supplier.

If an internal sound module amplifier channel is deactivated due to a short circuit, the screen indicates this by turning the symbol of the relevant corner speaker to red.

Simple connection test:

• a sound signal (e.g. white noise) lasting 1.5 seconds followed by a pause is sent to all four audio channels in sequence. The screen indicates which channel is being tested.
• If the test signal is not audible, the person carrying out the test must press a soft button with the indication "Error". The relevant coil symbol will go red. Otherwise it must go green.

it is not possible to detect open connections of internal amplifier outputs.

the NIT unit cannot detect short-circuits in electrical connections between the external amplifier and speakers.

Infrared remote control (IR)

The test carried out on infrared (IR) remote control buttons is similar to that run on NIT unit buttons: each remote control unit button is displayed on the screen as a symbol.

If the button pressed is detected by the NIT unit, the relevant symbol colour changes from yellow to green.

If a button is detected, the infrared (IR) connection incicator switches from yellow to green. If the buttons have not all been detected within 30 seconds, the symbols are marked as defective (i.e. red).

Simple operation test: to check whether the NIT unit is receiving an infrared (IR) signal, only one button need be pressed.

Radio aerial

The NIT unit automatically activates the radio and tunes it to a set frequency.

The signal intensity is compared with a minimum set level. If the result exceeds this level, the aerial passes the connection test.

OPERATION

Languages supported

The CONNECT multimedia system supports 5 different languages for the display of text and incomng and outgoing voice communications.

Languages may be configured by the user and are as follows:

• Italian
• English (UK or US)
• German
• French
• Spanish

The choice of language affects the behaviour of the following system modules:

• text display on NIT,
• voice recognition system (refer to the Owner Handbook for user instructions)
• navigation system module announcements.
• Telematic module events table.

SYSTEM OPERATING STATES

During operation, the system will be in one of the following status modes from the user viewpoint.

Turned on by means of ignition key (synchronous)

The synchronous operating mode is activated by measn of an NIT command. In his mode, system activation and deactivation is linked to ignition key status (Key_ON) - (Key_OFF).

If the system is turned off by pressing the knob before key-OFF, the system stays off at the next key-ON.

Turned on by button

Normal operating mode, available after the user has pressed the rotary volume knob. System activation by pushing the button is possible only after deactivation by means of the ignition key (Key_OFF).

Stand-by

The display and audio output are off. Some functions (e.g. the positioning function) still continue to remain active in the background. To gain access to stand-by mode, press the rotary volume knob while the system is active and the ignition key is in ON position.

Off

Complete system deactivation.

EXTREME SYSTEM OPERATING CONDITIONS

Processor load management

Process load is high following simultanous activation of voice recognition, map display and route calculation functions.

The CONNECT system guarantees that this does not give rise to unexpected results by managing priorities.

The system does not show any reaction, except a time lag for functions with lower priority.

The priority sequence is as follows: voice recognition, map display, route calculation.

Minimum voltage condition

- The system operates without any restrictions within a range between 10 and 16 V.

Between 7 and 10 V, system operation may be reduced while the CAN functions are not subject to any limitation. Below 7 V, the system could turn off but this does not interfere with the CAN bus.

In the interval between 7 and 10 V, the system enters into a mode similar to STAND-BY.

This means that the display backlighting and radio module are deactivated and keypad events (apart from IR remote controls and steering wheel controls) are ignored.

If the ignition key is in ON position, the system abandons STAND-BY mode when battery voltage again exceeds 10V.

If the ignition key is in OFF position (the system has been reactivated by pressing the On/Off button), the system goes off, e.g. it enters the OFF mode.

The system does not save data in its non-volatile memory if supply voltage drops below 10V.

Excess tension condition

In the interval between 16 and 23 V, the system is disconnected from the battery voltage by means of a hardware switch.

The system is again connected to battery voltage when the voltage drops below the overvoltage limit.

The overvoltage condition takes the form of a normal battery disconnection.

All unsaved information, e.g. user configurations, GPS almanac etc. are lost.

Minimum temperature condition

The system operates up to a minimum environmental temperature of -30 °C.

It is, however, possible for certain internal components to deactivate if their temperature limits differ from this value. These are, in particular, the CD, CC, GSM module and display. A special management system is therefore adopted in cases of low temperature.

Components are turned off on the basis of temperature limits, evaluated temperature and temperature of the nearest sensor.

The system is not designed to operate at temperatures below -40 °C.

If the system is reactivated (e.g. via CAN or a heater remote control), and a temperature of lower than -40 °C is measured, the system is turned off again.

External components (particularly the supplementary vehicle heater) may not therefore be turned on if the measured temperature is lower than the system limit.

In this case, the system cannot be restarted for the next 5 mintes. This feature allows the system to attempt to restore the temperature to operational levels.

Excessive temperature condition

The system limit environment temperature is +65 °C, since the internal temperature is some 20 °C higher, the system is able to withstand a temperature of 85 °C.

Within a range between +70 °C e +85 °C, the display is dimmed in linear manner from 100% to 20%. Within this temperature interval, the GSM module reduces its transmission capacity.

If the system deactivates due to excessive temperature, it cannot be reactivated for the next 5 minutes. This feature allows the system to cool to within the normal operating temperature interval.

PRIORITY MANAGEMENT

NIT unit priority management affects incoming and outgoing visual and acoustic sources. The concept is based on the following rules.

1. Three priority levels are present:

• emergency (level 1),
• urgent (level 2),
• normal (level 3),

2. Components do not alter priority as a result of external or internal conditions. A function cannot, however, be executed via voice control as long as a phone conversation is in progress (point 11).

3. Outputs are classified on the basis of content and not source. For example, a traffic warning message will take priority regardless of source (TMC or telematic unit).

4. Information or dialogue windows have a minimum display time of 2 seconds. During this period, they cannot be relaced even by messages with higher priority. This is to prevent the display from flashing.

5. Elements with different priorities that are located in different, non-overlapping areas of the screen will not block one another. An icon with higher priority located inside a status line will not therefore affect the display of a window displaying lower priority information in the middle of the screen as long as the relevant visual areas do not overlap.

6. If a component is associated with a visual output and an acoustic output other than a buzzer, each is allocated a different priority. If a resource (acoustic or visual channel) is occupied, the two outputs do not occur simultaneously. In this case, the component output corresponds onlly to the resource, which may be allocated on the basis of a priority table. This rule affects controls relating to manoeuvres and changes of context. The priority subdivision is indicated in the table below.

7. If an item needs an acoustic channel to indicate a visual output (e.g. a buzzer indicates a warning message), this waits until both resources are available to ensure a synchronised output.

8. With the exception of emergency calls and medical support, the user can change the context at any time (e.g. from the main page to the phone page) by pressing one of the hard buttons.

9. Items activated by the user are usually higher priority than items activated from the outside.

10. A phone call is always higher priority than a manoeuvre-related command.

11. During phone calls, it is not possible to carry out certain voice recognition actions.

12. The user may program the mix of sounds generated by built-in audio chips, with the audio source active at that moment. It is not, however, possible to mix sounds that are not generated by an audio chip (e.g. phone rings) with the audio source. These sounds bring about attenuation of the audio source.

13. The user may activate one single entertainment source (radio, CC, CDD, CDC, TV) at a time. This source may be interrrupted or suppressed (e.g. by mixing) by a higher priority source on the basis of the priority table shown below.

14. Traffic information obtained by means of a telematic information source (TMC or Viasat) are graded into 3 different priority categories. high (e.g. driving on wrong side of road), normal (e.g. traffic congestion along the route) and low (e.g. general information).

15. The dark operating mode is deactivated if it is superseded, for example, by a change of context.

16. Any conflict relating to command input sources is resolved on the basis of the following list (from high priority to low priority):

• remote control on the steering wheel,
• voice command
• NIT unit hard buttons,
• NIT unit soft buttons,
• NIT unit menu items,
• remote control.

Priority Table

CONTROL FUNCTION SUMMARY TABLE

This section lists execution methods for functions supported by the CONNECT Nav+ system

In general, most functions may be implemented by selecting a hardward button, a software button associated with a context or a menu item.

Some functions may not, however, be executed explicitly because they are dependent on the context. One example is the display of icons such as the phone signal intensity icon on the main page. The following tables do not show the functions that cannot be selected. An example of a function execution table is shown below:

The first column indicates the name of the function to be executed, while the other columns indicate possible modes. The last column on the right lists other possible input modes.

Volume control

At the time of deactivation, the NIT unit saves the volume levels and recalls them next time the set is turned on.

The volume may be adjusted within a range that is subdivided into 50 steps.

The volume settings is common to FM, AM, CD, CDC, CC and TV.

A special volume adjustment is reserved for traffic announcements, telephone and navigation system messages.

For navigation messages, the active sound source volume is reduced by a fixed quantity equivalent to 10 volume steps.

It is also possible to activate/deactivate the possibility of selecting 5 different values for volume adjustment on the basis of speed (SDV).

Volume limitation upon start-up

The NIT unit limits the volume to a presettable maximum value upon activation in order not to disorientate the user. If the volume is adjusted to a value higher than the maximum level when it is turned off, it is set to the programmed value next time the set is turned on.

Sound level

Sound level can be activated and deactivated (MUTE) by means of a selector by activating the specific field (1) from the NIT page in AUDIO mode. When the volume is low, the system automatically increases the intensity of bass and treble sounds for RADIO/CD/CC/TV entertainment sources only.

Bass/treble

The bass and treble level is adjustable from - 12 to + 12 in 25 steps.

Treble and bass selection values are saved individually for each RADIO, CD, CC and TV entertainment source. When the set is turned off, the settings are saved and then called up the next time the set is turned on.

For sources such as TA, phone and navigation system, the bass and treble levels are automatically adjusted to a neutral setting.

Fade/Balance

Fade and Balance controls are adjustable through 31 steps (from -15 to +15).

The Fade and Balance setting applies to all entertainment sources.

If the phone is activated, Fade and Balance are set to predefined values that cannot be altered by the user.

The previous values are called up again when the phone is deactivated.

When TA is activated, fade and balance levels selected at that time are used. These settings can be adjusted while TA is active.

The information sources (driving tips) mixed with the front entertainment source channel are not influenced by fade and balance settings.

These may be modified when the information source is active, but affect only the entertainment source.

Deactivation due to voltage drops

When voltage drops below 10V, the audio unit saves its current status and deactivates. As soon as the voltage re-stabilises, the audio unit reactivates automatically with the previous settings.

Audio source selection

Types of audio source

In the CONNECT system, AUDIO sources may be categorised by dividing them into entertainment sources and information sources that may be selected via softkeys (2).

The entertainment sources, some of which are options and may not be fitted, are as follows:

• Radio Tuner
• Audio CD player
• CD Changer
• Tape Player
• TV programme tuner

The information sources, always present, are as follows:

• Phone
• Traffic announcements (TA)
• Driving advice (navigation)
• User voice command request/confirmation (voice recognition)

Information source selection rules

Information souces may be mixed with front audio channels (in the case of driving advice) or replace the entertainment source (in the case of announcements relating to traffic, phone, voice recognition dialogue manager and acoustic signals).

If an information source has access to audio channels, i.e. if it mixes with or replaces the entertainment source, its volume may be adjusted by means of the volume control knob for as long as it remains active.

These volume level changes are not saved permanently.

The entertainment source volume level may not be altered for as long as an information source is active.

If several information sources are activated simultaneously, the situation is controlled by the priority management function as described previously.

Automatic activation of entertainment sources

When tape or CD is inserted in the CD and CC player, these are automatically selected as active entertainment sources.

When any of the information sources is active, the automatically selected entertainment source may become a background source.

The entertainment source is reactivated only when the information source ends and no other requests are pending.

Mixing voice commands with sources

Navigation module voice commands are distributed through the front speakers.

In this case, the entertainment source volume is reduced by a fixed amount equivalent to 10 volume steps in relation to the configured navigation volume.

As described previously, as long as the information source is actie, the driving advice volume may be adjusted by turning the volume knob without the entertainment source background volume being altered.

The user is free to decide whether to broadcast the driving advice through the left audio channel, the right channel or both.

Radio transmission receiver

Bands

The radio receiver is configured to operate in Europe. It manages the following bands: FM, MW and LW.

Upper and lower frequency limits and relevant step sizes are listed in the following table:

Stations

The receiver is able to store 30 stations, divided as follows:

• 6 FM-AS,
• 2 x 6 FM (FM-A/FM-B),
• 6 MW
• 6 LW

Current band and station

The receiver comes with a band referred to as a "current" band for temporary storage of the selection made by the user. Similarly, the receiver stores a current station/frequency for each band available.

This feature means that the system returns to the last selection set for a particular band when changing from one band to another.

Station selection

When the recall button is pressed for less than 3 seconds, a stored station is recalled. This operation modifies the current station/frequency.

If the station has been stored with RDS active and a PSN was available, the PSN is immediately displayed.

If the station was stored with RDS deactivated, the stored station frequency is re-loaded while the RDS function is disabled and some AF check is carried out.

If a local station without alternative frequencies is called up while the RDS function is enabled, the stored station frequency is reloaded. The RDS function is activated if it was previously deactivated.

The station recall continues until an exact PI is decoded. If synchronisation is not achieved within 6 seconds, the PSN recalled and displayed is replaced by the frequency value and no new station is scanned.

If another PI code is decoded on this frequency, the new RDS station is used and this will be stored in automatic mode.

Frequency selection

Frequency may be altered by means of a rotary encoder within the selected band. This operaration modifies the current station/frequency. If frequency is selected directly (i.e. manually), the RD and TP functions are deactivated and the receiver enters frequency mode.

Scanning higher frequencies

When this function is used, the system searches for the next station up from the current frequency.

If the upper edge of the frequency band is reached, the receiver skips to the lower edge of the band.

Search mode stops when:

• it is suspended by the user,
• the signal level of a station satisfies the preset threshold (programmable at EOL),
• the initial frequency is reached again.

The search is not started if it is detected that the car is driving through a tunnel.

If the RDS is enabled, the next station in the list of stations inside the receiver is selected (RAI MF1 - > RAI MF2 - > RAI MF3). RDS stations are then given priority, but non-RDS stations must also be detected at the end.

If TP mode is also active, only TP stations are selected.

If the RDS function is disabled, the receiver tunes to the next good-quality station within the frequency band.

Scanning lower frequencies

When this function is used, the system searches for the next station down from the current frequency.

The system behaves in the same way as for the "Scanning higher frequencies" function (described above) except the search is downward.

If the lower edge of the frequency band is reached, the receiver skips to the upper edge of the band.

Introductory scanning towards higher frequencies

When this function is used, the system searches for the next station up from the current frequency.

All stations are broadcast for 3 seconds, then the search is resumed from the next station.

Introductory upward scanning mode is suspended:

• if the user presses any button,
• if the starting frequency is reached again.

The new selected station becomes the current station if the function is suspended.

The new selected station becomes the current station if the function is suspended.

If TP mode is also active, only TP stations are selected.

If the RDS function is disabled, the receiver searches up within the frequency band to find good quality stations.

If TP mode is active, the system tunes only to TP stations. Non-RDS stations are also accepted. AM bands behave in the same way as FM bands with the RDS function deactivated.

The receiver audio is suppressed during the search. The active search mode is shown on the display.

Introductory scanning towards lower frequencies

The system behaves in the same way as with "Introductory scanning toward higher frequencies" (described above), except the search direction is downward instead of upward.

Storing current station

The current radio station is stored by pressing the recall button for at least 3 seconds.

Alternatively, this function may be carried out by means of a voice command: the user must specify the storage position by means of a number.

The user receives confirmation that a station has been stored by means of a short acoustic signal ("received beep") or by means of a short volume drop. PSN and RDS and TP function statuses (on or off) are stored together with the stations.

If the PSN is scrolled, the PSN displayed at the time when the user presses the station button is stored. RDS mode is set to off when a non-RDS station is stored.

TP selected mode (on or off) is stored together with the station and reset when called up.

Automatic store

The automatic store function stores the 6 strongest stations corresponding to FM-AS recall buttons. The automatic storage function is not active in AM bands.

When the automatic storage function is started, the FM-AS band is selected automatically.

The automatic storage function starts from the lower edge of the FM band and ends at the top edge.

RDS stations take precedence over FM station. During the automatic storage process, the display shows the frequency. As soon as a PSN is available, this must be displayed instead of the frequency.

Broadcasting chains are grouped together if the first element of a chain of stations (e.g. in the case of the RAI MF1, RAI MF2, RAI MF3, …, chain, the first element is RAI MF1) is one of the strongest stations, this station is defined as station number 1.

Example:

• The 6 strongest stations are

- The automatic storage order is

RAI chain stations are grouped.

The first of the RAI stations (Pi 0x5201 code) is put in first place.

The remaining elements are ordered on the basis of their PI code PI (for example DEEJAY 0x5214 is located before GEMINI 0x5353).

After automatic storage, the best station is tuned.

The automatic storage function takes about 30 seconds.

Automatic storage may be interruptd by calling up a station or by means of other interactions with the tuner (e.g. call up of a station and up/down scanning).

If it is possible to receive at least 6 stations with sufficient field intensity, the others are not affected.

Ignition

Upon system activation, the station selected at the time of deactivation is selected.

if the last stored station is not available, the first available station after the stored stations is selected.

if TP or TMC modes were not selected initially, the receiver takes this into account when selecting a new station.

If no station is available in the stored station series, a search is carried out for the next available station using the function "scanning higher frequencies" and taking into account enablement of TP or TMC modes at all times.

If no station is available at all, the last stored station is selected.

If the car is driven through a tunnel, no search procedure is carried out as long as this condition persists.

RDS functions

RDS enablement/disablement

The functions supported are defined by European RDS standard EN 50067 and is enabled or disabled by the user. RDS functions are available only in the FM band.

If the RDS function is disabled or a RDS station that transmits information, the receiver does not use any RDS function (PSN, EON, AF, PTY and TMC).

Traffic message channel

The NIT unit also allows decoding of TMC information. This may be used for dynamic navigation when made available to the user in text format.

If TMC or dynamic route driving via TMC functions are enabled (i.e.the system uses TMC information) and the TMC station weakens, no automatic radio station search is started.

The user must selet a new station manually, e.g. by calling up a stored station or starting a station scan.

if the new selected station is not a TMC station the user is informed by means of a warning message 20 seconds after station selection.

The user is asked to select a new TMC in manual or automatic mode or deactivate the TMC service.

Manual selection:

• A list of all TMC stations that can be received is presented. The user can make a choice from the list.

Automatic selection:

• The TMC station with the highest field intensity is selected from the internal list.

TMC service deactivation:

• If no TMC station is available, the relevant TMC service is deactivated in terms of text display and dynamic navigation and the user is informed by means of a warning message.

Traffic programme mode

Traffic program mode (TP) is enabled or disabled by the user by means of control (2) from the NIT page in AUDIO mode.

If traffic programme mode is enabled and the CC / CD / CDC players are working, when the traffic announcement funciton is activated (TA), the CC / CD / CDC stops and the incoming programme is activated..

When a traffic programe is active, individual programme settings are modifiable and the ser is able to stop the programme at any time.

If TP mode is enabled and the selected station weakens (i.e. the signal intensity becomes too low) for a period of at least 30 seconds, the receiver automatically checks to see if another TP programme is available within the entire FM band.

If no TP programme is detected, the TP search stops. Otherwise, the receiver automatically selects the next station with a TP signal. The selection starts with a search of stored stations. If no TP stations are found, the receiver searches for a TP station using the "scanning higher frequency" function. If no TP station can be identified using this method either, the frequency to which the set was tuned before beginning the search is re-selected.

If the user enables TP mode and the current station is not a TP station, the receiver automatically selects the next station with a TP signal within 6 seconds by means of the procedure described above. If no TP station is detected, the receiver automatically tunes to the station selected before starting the search procedure while the user is informed of the error. TP mode is disabled.

Display of programmed station name

This function allows the name (PSN) of the programmed station to be displayed, if available. It applies only to FM bands.

The PSN is considered valid if successfully received at least twice. If no name is available, the frequency is displayed in place of the PSN.

If a station is stored while the RDS function is active (ON), the stored PSN is displayed in the station list. Conversely, if the station is stored while the RDs function is deactivated (OFF), the frequency is displayed in the station list.

RDS programme type

The RDS (PTY) programme type is selected by means of control (4) from the NIT page in AUDIO mode. This function is used as an RDS station selection filter and allows a particular programme category to be selected from among the options available on the specific submenu.

When this function is selected, the radio begins to search from the current frequency and stops if it detects a station with this PTY. If no PTY is detected, the search stops at the frequency from which it started.

If a message with PTY 31 code (general emergency situation) is detected, its contents are immediately forwarded. This interrupts all other entertainment sources including phone calls.

CC PLAYER

The CC player is built into the Audio module and is used to play tapes.

Operating modes

The tape player can be controlled by means of softkeys in the CC submenu from the AUDIO menu and by means of two hardkeys on the control panel. The following operating modes are available:

• Pause
• Play
• Fast Forward
• Fast Rewind
• Scan

When the use removes a tape from the player, the player stops.

When the user inserts a tape in the player, the player automatically switches to play mode.

When the user selects the pause control, the tape player switches to pause mode.

The tape player stops during trafic announcements and phone calls.

During navigation system announcements, the tape player continues if in play mode and mixing of the two audio sources is managed as described previously.

AUDIO CD

The CD player offers 8 operating modes:

• Stop (not directly accessible)
• Pause
• Play
• Scan
• Shuffle
• Repeat
• Search Forward
• Search Backward

CD CHANGER

In the description given below, the term "first disc" indicates the CD inserted in the slot marked by the lowest number and consequently the term last disc indicates the CD present in the slot corresponding to the highest number.

Previous disc and next disc: the presence of empty slots is permitted.

Consider, for example, that CDs are inserted in slots 2 and 4. The first disc is the disc in slot 2 and the last is the disc in slot 4.

If the disc inserted in slot 2 is selecte, the next disc is the one in slot 4. If the CD in slot 4 is selected, the next disc is the one in slot 2 which, in this case, is also the previous disc.

The NIT unit automatically recognises the presence of a CD changer.

CD changer functions are accessible only if the CD changer is available.

Operating modes

The CD changer offers 6 operating modes:

• Stop (not directly accessible)
• Play
• Repeat
• Shuffle
• Search Forward
• Search Backward

When at least one CD is inserted in the player, it is detected automatically and the player begins to play the first track of the first disc.

The CD changer identifies a current track and a current disc. The first track on the first CD is selected when a new CD is inserted or when the current disc is removed.

When the CDC changes to stop mode, the first track of the current CD is selected.

TV TUNER MODE*

Main TV functions page

The main TV tuner functions page is displayed by pressing the SRC button (1) and selecting the TV mode or directly using the TV multifunction button in the screens where the audio sources are shown at the base of the display (FM - AM - CC - CD -CDC-TV)/

ON-BOARD COMPUTER

The computer displays outside temperature and also supplies a set of information using the display modes shown in the following table:

Dual trip memory

The NIT unit supplies two trip memories (Trip A = "continuous", Trip B = "from hh:mm", the first (Trip A) displays information from the first zero reset carried out by the user, while the second (Trip B) displays the information from the last zero reset carried out by the user or the last automatic reset.

The count/update of these values is valid only if the NIT unit receives a fuel consumption signal (including cut-off condition (more than 300 rpm.)).

Zeroing trip memory

The user is able to zero the trip memories manually.

Trip memories are zeroed automatically if:

• Route length exceeds 4999.9 (kilometres or miles),
• the user changes the display units from miles to kilometres and the route length following this conversion operation exceeds 4999.9 kilometres.
• trip time exceeds 99:59,
• the battery is disconnected,
• a zero operation is carried out for Trip A (only for Trip B),
• apart from these conditions, the Trip B memory must be zeroed if the time between deactivation and the next activation exceeds 2 hours.

If a single trip memory value is zeroed, all values of this trip memory are zeroed (Trip A/B).

Display of journey time

Trip time from the last zero reset carried out by the user or automatic zeroing is taken as the trip time.

After a zero operation, all values are returned to "00:00".

The value at the time of the last deactivation is displayed upon each activation.

After deactivation, the trip time calculation is suspended. The counter increases only as long as the ignition key is turned to ON, i.e. as long as the IDIS system is in ACTIVE_ON_KEY_ON mode (active due to ignition-operated activation).

The maximum stored time value is "99:59".

Display of arrival time/time elapsed (BC007)

If the distance to the destination is known, the estimated arrival time and time elapsed are calculated and displayed on the NIT.

Display of distance travelled

The system displays the distance travelled during the current trip from the last zero reset.

The maximum value is "4999,9 km" (miles).

The resolution is "0.1 km" (miles).

The value is updated every 0.1 km (miles).

Display of average consumption

Average fuel consumption is calculated using the equation:

• average consumption = distance travelled/quantity of fuel consumed.

The displayed value refers to the average consumption for the current trip.

At the beginning of a new trip (zero) or following battery connection, the displayed value corresponds to a preset data equivalent to 10 km/l.

The initial value is weighted to prevent great fluctuations during the first few minutes. After this period, the average fuel consumption displayed reflects the measured value.

During the first 10 seconds, the value "----" is displayed.

The value at the time of the last deactivation is displayed upon each activation.

When the car is at a standstill, the value is calculated using the instantaneous fuel consumption signal (increase nil).

The resolution is "0.1 km/l" (mpg).

Calculation precision is = < 0.1 km/l

The value is updated every 10 ± 1 seconds or after 0.1 km (miles), whichever comes first.

Maximum value: 50 km/l - 2 l/100 km - 99.9 mpg

Minimum value: 4 km/l - 25 l/100 km - 2 mpg.

Display of instant consumption

The value is calculated using the instantaneous fuel consumption signal received via B-CAN.

Instantaneous fuel consumption is calculated so that the user is able to be aware of the fuel consumption change but without major fluctuations.

At the beginning of a new trip (zero) or following battery connection, the displayed value corresponds to a preset data equivalent to 10 km/l, but the value "---" is displayed during the first 10 seconds.

The initial value is weighted to prevent major fluctuations during the first few seconds.

After this period, displayed instantaneous fuel consumtion reflects the measured value.

The value at the time of the last deactivation is displayed upon each activation.

The resolution is "0.1 km/l" (mpg).

Calculation precision is = < 0.1 km/l

The value must be updated every t _REFRESH seconds.

Maximum value: 50 km/l - 2 l/100 km - 99.9 mpg

Minimum value: 4 km/l - 25 l/100 km - 2 mpg.

Display of distance that can be travelled depending on fuel level

This value indicates the distance that can be covered with the remaining fuel if the driving style remains unchanged. This is calculated from:

• current speed,
• maximum fuel quantity that the tank can hold (EOL programming),
• fuel level gauge,
• instantaneous fuel consumption.

The equation used for the calculation is as follows:

• Distance (km) = reference average fuel consumption [km/l] * quantity of fuel present [l].

Reference average fuel consumption is given by average fuel consumption for the last 5 minutes of the current trip.

If the fuel level in the tank is lower than a minimum vale corresponding to a distance of 50 km, the distance range is calculated without using the fuel level (because the fluctuations are too big).

the value "----" is displayed for the first 30 seconds at the beginning of a new trip (zero) or after battery connection.

The value at the time of the last deactivation is displayed upon each activation.

During the trip, the distance must be updated by making increases proportional to the distance between the displayed value and the calculated value (without major fluctuations).

• if the distance is > 40 km, distance must be altered by the difference/6
• if 6 = < the difference = < 39 kilometres, the distance must vary by about 3 km
• if the difference is = < 6 kilometres, the distance must vary by about 1 km

If the fuel level drops to the reserve (warning light) and distance is less than 50 km, the NIT unit does not display any distance range value. Instead the distance is calculated continuously.

The message "Attention" is displayed on the NIT unit. Refuel" and then the distance range reading becomes "----".

If the distance range is less than 50 km, the display shows the reading "----".

When the car is at a standstill (speed < 3 km/h) and the engine is on, the last value is displayed for 3 seconds. The NIT unit must then display the reading "----" while the distance range calculation function remains active.

When speed exceeds 3 km/h again, the distance range indicator switches back to normal mode. The new value is calculated taking into account fuel consumption during the last 5 minutes prior to the car halting.

The distance range value is calculated to prevent the car running of out fuel even if the distance range shown is > 0 km.

Technical requirements:

• calculation precision: 1 km
• resolution: 1 km
• update of displayed value every 30 s ± 1 s
• minimum displayed value: 50 km. If the distance range is lower, the display shows the reading "----".

Recognition of refuelling

The system recognises a refuelling condition if a minimum amount of fuel equivalent to at least 5 litres is introduced between car deactivation (KEY_OFF) and start-up (KEY_ON) using the ignition key.

Display of average speed

Average speed is calculated by means of the equation:

• average speed = distance travelled during trip/trip time

The calculation is carried out only if the engine is on.

The value "----" is displayed for the first 10 seconds following a zero reset or at the beginning of a new trip. The system then displays the calculated value.

The value at the time of the last deactivation is displayed upon each activation.

Technical requirements:

• The resolution is "0.1 km/h" (mph).
• Calculation precision is = < 0.1 km/h
• IThe value is updated every 10 ± 1 s.

Zeroing average speed

Trip A: average speed may be zeroed by selecting "Continuous zeroing"

Trip B: average speed may be zeroed by selecting "Zero from hh:mm" or it is zeroed automatically when more than 2 hours elapses from deactivation.

Display of speed limit

The NIT unit displays the current speed limit and its activation status (enabled/disabled).

If the speed limit is exceeded, the NIT unit displays a warning message and sends an acoustic signal.

Change speed limit

The user can change the speed limit within a speed interval between 5 km/h (3 mph) and 300 km/h (180 mph).

If the ACC function is present, the maximum speed limit value will not excee the ACC speed limit, which is equal to 170 km/h (105 mph).

The default delivery value is SPEED_LIMIT_DEFAULT (DEFAULT SPEED LIMIT). This is programmed as 130 km/h at the EOL.

The last available value is displayed after connection to the battery.

If the display units are changed, the speed limit value is converted to the new units.

Activation/deactivation of speed limit buzzer

When the speed limit buzzer is activated, the user is notified by means of a message window and an acoustic signal.

Otherwise, the user is notified only by means of a message window.

Activation/deactivation of speed limit

After setting a speed limit, the user can activate it.

If current speed exceeds the speed limit, a warning message is displayed while an acoustic signal (if enabled) warns the user to slow down.

PLANNING (SERVICES)

Display of planning items

The NIT displays technical service information in a list (planning items).

This information consists of technical service information programmed by the user and manufacturer.

Selecting a planning item

The user can select one technical service information item for display, modification or deletion.

Change a planning item

The user can modify selected technical service information items only if the items are programmable by the user.

The manufacturer’s technical service information may only be displayed, not modified.

Creating a new planning item

The user can create new technical service information items. The following fields may be modified:

• Text
• Date and mileage

Deleting a planning item

The user can delete technical service information.

It is possible to delete only technical service information items created by the user. It is not possible to delete manufacturer’s technical service information items.

Announcement when a planning item date or mileage is reached

The user is informed by means of a message window and an acoustic signal (buzzer) when a technical service item date or mileage is reached.

INTERFACE WITH EXTERNAL ECUs

Acoustic interface

Acoustic interface with parking sensor

The B-Can node of the parking sensor (NSP) may require the emission of different sounds with different volume levels on one or more of the four channels present on the car.

All directional channel information is controlld by attenuation and balance settings.

Since no synchronisation mechanism is specified for an acoustic output request, the parking sensor is not informed if its request is cancelled by elements with higher priority.

Gateway functions

Low engine coolant level message

The digital signal "low engine coolant level" is received periodically at an NIT unit digital input and transferred to the instrument panel via the B-CAN network.

This digital input is protected by means of a hardware circuit and short circuit or open circuit conditions cannot therefore be detected. No subsequent signal processing operations are carried out (e.g. echo elimination).

Low screen washer fluid level message

The digital signal "low washer fluid level" is received periodically at an NIT unit digital input and transferred to the instrument panel via the B-CAN network.

This digital input is protected by means of a hardware circuit and short circuit or open circuit conditions cannot therefore be detected. No subsequent signal processing operations are carried out (e.g. echo elimination).

Exterior lighting sensor activation level message

The NIT unit downloads the level of the encoder that the user can use to set the exterior lighting sensor activation level. This value is transferred to the car on-board computer via the B-CAN network.

If a value within a range of 100 mV from the lower limit or upper limit of the input range is measured, this value is treated as a short circuit to earth or to the power supply respectively. In this case, the default value is used and a fault diagnosis code is saved.

The presence of an open circuit is treated as a short-circuit to earth.

Distribution of system date and time

The NIT unit distributes information on system date and time to the other nodes via B-Can. The time is always in 24-hour format, regardless of the display mode selected by the user.

Display access

Text messages present

The on-board computer node (NBC) can ask the NIT unit, via B-Can, to display text messages in a message window on the screen.

These messages are called up by means of a code number sent by the NBC.

These text messages must be confirmed by the user. The results of this confirmation (OK or delete) must be re-sent to to the node responsible for making the request).

The NIT unit does not carry out any software checks, apart from managing priority in relation to other messages on the screen.

Because no synchronisation message is present, the NBC unit is not informed when the display is not turned on.

Code input request

The on-board computer node (NBC) can ask the NIT unit, via B-Can, to ask the user to enter a 5-figure vehicle code number. The NIT unit must also display an accessory text message (called up by means of a code numer).

The combination of figures entered by the user and/or interaction with the user (OK or Delete) are sent back to the NBC unit.
