IN CAR ENTERTAINMENT

DESCRIPTION AND OPERATION

86-6-9

Inputs and outputs
The radio cassette player receives a mute signal from the telephone system if a call is received, when the call finishes 
the mute is removed and the system resumes play. Inputs are also received from the steering wheel control system 
(mid line and high line sytems). When the system is turned on, the high line systems radio cassette player:

l

sends a 'power on enable' to the power amplifier

l

sends an 'enable' signal to the radio headphone amplifiers. 

On the high line system the radio cassette player also sends and receives signals from the CD-autochanger and rear 
headphone amplifiers (if fitted). On high line systems the radio cassette player sends audio signals to the power 
amplifier.

Remote radio steering wheel controls (midline and high line systems)
The remote radio control switch is located on the LH side of the steering wheel and is secured with two screws. The 
wiring from the remote radio control switch plugs in to a connector that is part of the steering wheel rotary coupler. 
Operation of the remote radio control switches allow the driver to control the ICE without releasing the steering wheel. 
Volume, mode and selection functions can be carried out using the steering wheel mounted control switches. Control 
inputs from the remote radio control switches are sent to the radio cassette player.
