General description

GENERAL DESCRIPTION

The vehicle is preset for the installation of a car radio and four speakers.

The front loudspeakers are located to the side on the upper part of the dashboard, while the rear loudspeakers are located on the shelf below the rear wind screens.

The housings equipped with the relative connector for the speakers are already present in the vehicle as is the radio housing and relative connectors.

The aerial is integrated in the heated rear window device, connected by a coaxial cable to the radio itself. The vehicle is also preset for the installation of an external electric aerial, automatically operated when the radio is switched on. The radio circuit is constantly powered and it can be switched on at any time, even when the ignition key is disengaged.

N.B. Some versions are equipped with a radio system complete with speakers and removable radio. Information regarding this is given in the next section "Radio system".

FUNCTIONAL DESCRIPTION

The radio O4 is powered directly by the voltage from the battery through fuse F2 (20A) in fusebox G1, to pin 2 of connector C; Pin 1 is grounded.

The signals are emitted from connector B towards the front loudspeakers O5, connected by preset connectors G218 (right) and G217 (left).

The signals towards the rear loudspeakers O5, connected by the preset connectors G196 (right) and G195 (left) are emitted from connector A.

NOTE: The routing of the wires differs depending on the version.

Pin 5 of connector A is connected to the control unit N49, which permits the device integrated with the heated rear windscreen to be used as an aerial O3, or the electric aerial to be used through the preset connector G193.

This arrangement permits the motor of the electric aerial to be supplied with battery voltage through fuse F16 (7.5A).
