Functional description The radio P20 is supplied directly (4of connector A) from the battery via the line of fuse F39 of theunit under the dashboard B2. Pins 1 and 3 of connector A receive theCAN line with which the radio P20 is connected to the BodyComputer M1 and the other nodes of the system. Pin 8 of connectorA is earthed. The aerial P25 is connected to the radioalso via the specific coaxial cable and is supplied by pin 5 ofconnector A of P20. Pin 6 of connector A of P20 receivesthe supply for the lighting (with the side lights on) of the actualradio display, pin 40 of connector E of M1. Radio P20 is not connected to the radiocontrols on the steering wheel: the connection is via the clockspring D47, which is a node of the CAN SeeE1050 CAN CONNECTION LINES . Connector E of P20 has the cable connectedto the CD player P75. Connector B of P20 sends out cables carryingsignals to the speakers:The cables with the signals to the loudspeakerscom out of connector B; these signals are sent to the amplifierBOSE P70, which controls the loudspeakers. pins 5 and 6 to the left front loudspeaker P35 , pins 3 and 4 to the right front loudspeaker P36, pins 7 and 8 to the left rear loudspeaker P30 , pins 1 and 2 to the right rear loudspeaker P31. The amplifier P70 is supplied directlyfrom the battery to pin 1 - through the line of fuse F54 of theadditional fuse box B98. It is then connected - pin 6 - via a specificline to the radio P20 - pin 6 of connector C - which sends thesignal to switch on the amplifier. Pin 2 of the amplifier P70 is earthed. The other signals coming from the BOSE amplifier P70 control, as described above, the loudspeakers. The rear subwoofer P49 is located nextto the unit containing the amplifier P70 and is directly connectedto it. pins 3, 11, 12 e 15 of P70.
