The radio P020 receives a direct battery supply at pin A4 of connector A via the line protected by fuse F36 of the Body Computer M001 (pin 10 of connector G).

This direct battery power supply is protected upstream by fuse F71 (CPL1) of the B099 maxifuse control unit on the battery (connector D).

The radio also receives an ignition-controlled power supply (INT) at pin A7 of connector A along the line protected by fuse F49 also located in the Body Computer M001 (pin 15 of connector G).

It is connected, via pin A8 of connector A, to the centre dashboard earth C022 (connector A).

The CAN line reaches pins A1 and A3 of connector A which also connects the radio P020 to the other system nodes.

The radio P020 is connected to the radio aerial P025 via connector B.

On request, the aerial can be located on the right door mirror P061 (pin 1 of connector C). In this case the aerial receives a power supply via the connection between pin 1 of connector B of P061 and pin A5 of connector A of the radio P020.

Connector A of the radio P020 is also connected to the speakers:

• pins B5 (+) and B6 (-) to driver's front speakers P035 (mid-woofer) and P045 (tweeter);

• pins B3 (+) and B4 (-) to passenger side front speakers P036 (mid-woofer) and P046 (tweeter).

On versions equipped with a conversion socket, the radio P020 also has a connection for installing rear speakers, if fitted:

• pin B7 (+) and B8 (-) for the left rear speaker;

• pin B1 (+) and B2 (-) for the right rear speaker.

The Body Computer M001 is connected to the radio controls on the steering wheel via the clock spring D047. Specifically:

• the reference earth signal from pin 53 of connector H of M001 is received at pin 2 of D047;

• the signal is sent (through a dedicated resistive divider), from pin 3 of D047, for the MUTE, VOL+ and VOL- controls (located to the left of the steering wheel) to pin 38 of connector H of M001;

• the signal is sent (through a dedicated resistive divider), from pin 4 of D047, for the SOURCE, SCAN+ and SCAN- controls (located to the right of the steering wheel) to pin 51 of connector H of M001.
