NAVIGATOR OPERATIONAL DESCRIPTION

Operational Description

The radio-telephone-navigator system is integrated in the info-telematic control unit M065 which is supplied at pin A7 of connector B directly by the battery via the line protected by fuse F39 of the junction unit under the dashboard B002.

The CAN signals arrive at pins A1 and A3 of the same connector, through which the info-telematic control unit M065 is connected to the Body Computer M001, the instrument panel E050, the control unit on the steering wheel M093 and the roof control unit M062.

Pins 16 and 17 of connector A receive signals coming from the microphone fitted inside the roof control unit M062 which is also supplied directly by the battery (at pin 10) via the line protected by fuse F39 of the junction unit under the dashboard B002.

The GPS/GSM aerial P110 is connected to the info-telematic control unit M065 through the coaxial cable. The navigation inputs transmitted by the controls on the steering wheel are distributed via the CAN from pins 3 and 4 of the control unit on the steering wheel M093. It is supplied at pin 1 of the line controlled by the ignition (INT) protected by fuse F49 of the junction unit under the dashboard B002. The control unit M093 is connected to the rest of the vehicle by means of the clock spring coupling D047.

The signals from the CD CHANGER, which contains the CDs with the navigation maps, reach connector G of the info-telematic control unit, pins 13, 14, 15, 16 and 17 (see wiring diagram E3510 Radio for the connections).

The speedometer signal for the navigation, supplied by the braking control unit M051, which is also repeated at line C of the CAN from pins 1 and 2, reaches pin 7 of connector A of the Body Computer M001. The control unit is supplied at pin 12 directly by the battery via the line protected by fuse F02 of the engine compartment junction unit B001.

Lastly, the signals for the speakers to mute the volume during auditory navigation instructions leave from connector D. (see wiring diagram E3510 Radio for the connections).
