Location of componentsComponents DescriptionOn request, a road-map "Navigator" is available, integrated in the dashboard. The navigator allows the driver to know the position of his vehicle at every instant, by displaying it on the map, and helps the driver reach the desired destination. The system also allows the driver to obtain easily additional information on services of general interest (hotels, car parks, restaurants, pharmacies, service stations, hospitals, workshops, railway stations, airports, etc.).An electronic control unit, under the driver's seat, manages the operation of the entire system. In addition, a power supply is located beside the central unit which generates several outputs with stabilized voltage values.A CD player is incorporated in the central unit: it reads the CDs containing the mapping and all the other information relating to a country.The gyroscope - located inside the central unit casing - detects the rotation of the vehicle and enables the map to be orientated.The central unit casing also houses the GPS receiver, which processes the GPS (Global Positioning System) functions required by the navigation system:initial location of the vehicle;initial self-calibration of the sensors (milometer and gyroscope);assistance with navigation (check on correct location of the vehicle in relation to that detected by the sensors);synchronization of the central unit internal clock;location of the vehicle in areas not covered by maps and in the case of transported vehicle (ferry, train, etc.).
A GPS satellite aerial, located in the interior rearview mirror mounting, permits GPS (Global Positioning System) satellite location of the vehicle: the aerial is connected to the relevant receiver in the central unit by means of a specific shielded cable.A removable 5.6" colour display has two possible installation positions: one oppposite the driver, and a more central position. The display is easily extracted using a lever and can be moved from one position to the other. The display shows the selected route; the speaker accompanies the display with voice messages in various languages. The display incorporates a speaker at the rear for the voice messages.A wireless infrared remote control activates the system, sends commands to the display and enters data.The remote control has no attachment point in the car, but is free standing.

The system control unit supply line is protected by a special fuse located next to the junction unit.The system comprises an auto-activation logic controlled by the opening of the driver's doodr:when the door opens, the system is activated automatically;if during the next 3 minutes the ignition is switched on, the system stays onif nothing happens during the next 3 minutes and the door is reclosed, the system switches itself offwhen the ignition is turned off, the system switches itself off after 6 minutes.
Functional description The optional services relay J60 controls the supply circuit for the navigation system control unit M90 . The coil for relay J60 is energized when the ignition is switched on (INT) by the line for fuse F8 of the junction unit B1 , whilst the supply to the relay contact arrives directly from the battery via the line protected by the maxifuse J/B2 of B5 and by fuse B14 . The relay, controlled by the ignition (INT), supplies the control unit M90 to pin 3 of connector B; pin 2 of connector B is supplied directly by the line protected by the maxifuse J/B2 of B5 and by fuse B14 . Connectors A and B of M90 are connected to the feeder:pins 2 and 3 of connector B, as seen, receive supplies;pin 1 of the connector is connected to the vehicle earth.pin 4 of connector B receives the signal for auto-activation controlled by the opening of the driver's door: the signal comes from the switch in the front door I16.
Connector A of the feeder is then connected with the actual control unit M90 to connector D, providing signals at various voltages levels and stable earths. Connector C of M90 is for the GPS receiver inside the control unit which is connected with the GPS aerial P29 . Connector E of M90 is for the outputs - audio and video - for the monitor E65 : in reality, the connection takes place through a junction unit in the centre of the dashboard, from where two specific connections for the two, identical monitor mounting bases, positioned, one opposite the driver and the other more centrally, depart. Connector F for M90 is for the signals received from the other vehicle systems:at pin 7 of connector F the control unit receives the speedometer signal, coming from the instrument panel E50 at pin 5 of connector F the reverse gear engaged signal (2888892SeeE2022REVERSING LIGHTS) arrivesthe pin for connector F provides the earth for the speedometer signal
Connector G for M90 is for connection with the radio P20:a signal leaves pin 9 of connector G for the MUTE function (the volume of the radio is switched off or turned down when the navigation system issues voice messages).pin 1 of connector G is earthed
Connector H of M90 is connected to an earth point on the control unit bracket. Fuse power supply ignition operated excl ignition (INT/A)
