DescriptionThe vehicle is also available, on request, with preparation for the installation of a mobile phone. This system includes:connection for a mobile telephonehands-free function through the radio speakersoutside aerialThe connection for the telephone comprises all the supplies and signals necessary for the operation of the telephone.The aerial is mounted on the rear of the roof: it is a dual function aerial with two cables: one is the actual radio aerial, and one is the telephone cable, with dual reception band (GSM-ETACS at 900 Hz and D.C.S. at 1800 Hz). The radio receives as input the audio signals from the telephone connection. The operation of the telephone, temporarily switches off the radio (MUTE function).The telephone connection has a direct battery supply protected by two fuses, one in the junction unit under the dashboard and one in the body computer node.
Functional description The radio receiver node M094From connector A:pin 4: receives the direct battery supply, from the line protected by fuses F39 and F01; the supply is also provided to the junction D075; pin 7: receives the ignition-dependent supply from the line protected by the fuse F35;pin 8: connection to earth C020 connector B; pin 6: receives the side lights 'on' signal, for managing the instrument illumination; the same signal is also supplied to junction D075; pin 5: connection to the aerial P025; pins 1, 3: connection to the CAN networkSee E1050 CAN CONNECTION LINES .767The earth C020 is secured to the floor, and is positioned near the front right wheelarch (foot area). The junction D020 is housed, in the interior compartment, at the bottom of the front right pillar, near the door cable pass, passenger side.From connector D:pins 7, 8: receives the IN+ and IN- signals coming from the junction D075; pin 12, supplies the earth reference to the junction D075; pin 9: receives the MUTE signal, for temporarily switching off the radio function.
