Battery voltage is supplied by the low power drive from the BCM. The BCM energizes the multifunction relay K134 and B+ is input into terminal F1 of the radio from the multifunction relay K134. Ground is supplied at all times to terminals E16 and F5 of the radio.

The base audio system contains the radio and the speakers in all four doors. The optional cellular telephone and the compact disk changer can also be added to the base system. The connector wiring is present in the vehicle and ready for hook-up for either the cellular telephone or the compact disk changer.

The base system, as well as the up-level Bose system use the rear window defogger as the antenna. The signal from the rear window defogger is input into the radio antenna amplifier. The radio antenna amplifier filters and amplifies the signal and outputs the signal to the radio by use of a coaxial cable.

The Bose system is custom tailored to match the specific acoustic characteristics of the vehicle's interior. The system is designed to provide the maximum of freedom for styling, while providing excellent performance. The entire system takes into account the absorptive and reflective characteristics of the seats, windshield, seat coverings, instrument panel, door shapes, speaker placement and occupant placement. The systems' speakers are arranged in a cross-firing pattern in the car which gives both the driver and the passenger the stereo everywhere effect, similar to that of a live performance.

The Bose system contains the radio, the door speakers, the rear deck speakers, the sound processor interface and the radio speaker amplifier. The optional cellular telephone and the compact disk changer can also be added to the base system. The connector wiring is present in the vehicle and ready for hook-up for either the cellular telephone or the compact disk changer.

Both radio systems incorporate electronic memory for the pre-selected stations. The pre-selected stations must be reset whenever the vehicle battery is disconnected or is otherwise lost to the radio.

When the PARK LAMPS are turned ON, the headlamp switch supplies a voltage to terminal E5 of the radio. This voltage illuminates the radio display . The radio display dims along with the interior lights when controlled by the dimmer switch, which is part of the headlamp switch.
