CONNECT - Functional description

Functional description

The integrated radio-telephone-navigator P20 is supplied directly (7 of connector A) from the battery via the line of the fuse F39 of the unit under the dashboard B2.

Pin 4 of connector A receives a supply from the INT line protected by fuse 49 of control unit B2.

Pins 1 and 3 of connector A receive the CAN line with which the display P20 is connected to the Body Computer M1 and the other nodes of the system. In this way, the navigation system module inside the CONNECT system also receives information such as speedometer signal, reverse signal, fuel consumption etc.

Pin 8 of connector A is earthed.

Connector B of P20 sends out cables carrying signals to the speakers through which the voice messages are sent: See E3510 RADIO

Radio P20 is not connected to the radio controls on the steering wheel: the connection is via the clock spring D47, which is a node of the CAN network.See E1050 CAN CONNECTION LINES

The GSM reception aerial P25 is connected to the navigation system module via an appropriate coaxial cable different from that used for the radio and that used for the navigation function (GSM).
