The radionavigator P20 receives a direct power supply (pin 12 of connector A) from the battery via the line for fuse F36 of the Body Computer M1;

Pin 16 of connector A is earthed.

Pins 10 and 13 of connector A receive the CAN line by which radio the P020 is connected to Body Computer M001 - pin 18 and 22 of connector D - and to the other system nodes.

The Body Computer M001 is connected to the radio controls on the steering wheel via the clock spring D047: pin 35 of connector D provides the reference earth at pin 6 of D047; pin 52 of connector D of M001 receives the signals from the buttons to the right of the steering wheel, whilst pin 50 of connector D of M001 receives the signals from the buttons to the left of the steering wheel.

The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001.

The Body Computer M001 receives an ignition-operated power supply (INT) at pin 11 of connector E.

Pin 9 of connector E of M001 provides the Body Computer with a reference earth.

The amplifier P070 is supplied directly by the battery - at pin A4 - via the line for fuse F60 of the luggage compartment junction unit B045; pin A8 of the amplifier P070 is earthed.Pin C8 of P070 is then connected to the radionavigator P020 - pin 14 of connector A - which provides a positive enablement signal to turn the actual amplifier on.
