DescriptionThe navigation system informs you of the vehicle's position on the map (in relation to both urban and non-urban/motorway road networks), by showing it on the CONNECT display.In this way, the driver is taken to the desired destination, guided step-by-step by voice messages and visual information. The system also provides additional information for reaching services of general interest, such as hotels, car parks, restaurants, pharmacies, service stations, hospitals, ALFA ROMEO garages, railway stations, airports, etc.If present, the navigator is included in the integrated radio-telephone-navigator.(N.I.T = Nodo Info Telematico - Info Telematic Node). referred to as CONNECTThe navigation system uses the GPS (Global Positioning System) satellite location technology; it has the following functions:vehicle locationcalculation of the routeidentification of 'route guidance' manoeuvresmanagement of the map data base (on CD-ROM)cartographic display (pictograms or maps)emission of corresponding voice messagesThe navigation CD-ROM reader is located in the unit itself.768
767the navigation system operates only with the CD-ROM inserted in the specific drive; however it is possible to listen to a music CD during navigation. In this case, the navigation function requires the map CD to be inserted during execution of the route calculation procedures.
The GPS system consists of an aerial which allows the GPS satellite location of the vehicle: the aerial is connected to the relevant receiver, located in the integrated unit, via a specific shielded cable.The fishpole antenna is mounted at the rear of the roof: it has three functions as it also incorporates the GSM aerial and radio aerial.The vehicle position is identified by the analysis of the GPS data and the speedometer and reverse gear signals coming from the car.This position is shown on the display together with the topographical features of the area memorized on the CD. - In addition the Navigator generates a 'speech synthesis' which, viat the audio circuit, allows the driver to hear the driving instructions.The integrated radio-telephone-navigator unit is a node on the CAN network, through which it exchanges information with the Body Computer and the other electronic units (for example the navigation system acquires the odometer, reverse gear engaged, etc. information)The navigation commands displayed on the radio's display are repeated on the instrument panel ('HIGH' version).By means of an appropriate menu activated by the control buttons located on the panel beside the steering wheel, the entire system can be configured and in particular the units of measurement and the display language.

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 and maxifuse CPL of B99 . The supply to side lights on reaches pin 4 of connector A 3023264SeeE2530INSTRUMENT LIGHTING . Pins 1 and 3 of connector A receive the CAN line with which the radio P20 is connected to the Body Computer M1 and the other nodes of the system. Pin 8 of connector A is earthed. The aerial P25 is supplied from pin 5 of connector A. The aerial containing the GPS reception device is connected to the navigator module by means of the specific coaxial cable. Connector B sends out cables carrying signals to the speakers through which the voice messages are sent:The 'MODE' buttons of the H10 controls unit are supplied by the line (INT) protected by the fuse F39 of control unit B2 , and send the command to the instrument panel E50 , pin 16 of connector B. The instrument panel E50 is in turn connected via the CAN network to the Body Computer M1 and the integrated radio-telephone-navigator P20 .

Follow these precautions.769On batteries with an opticam hydrometer,electrolyte level and battery charge status can be monitored qualitativelyby examining the indicator colour: a light, bright colour indicates low electrolytelevel: top up with distilled water;a dark colour without a green area in thecentre indicates that the electrolyte level is correct but chargeis low: recharge the battery; a dark colour with a green area in themiddle indicates that both electrolyte level and charge status arecorrect: no action is necessary. For further details, see DESCRIPTION ANDOPERATION - 5580.768Proceed as follows.Check the battery voltage without loadusing the test device recommended by the Service outlets (e.g. 'MICRO360'). Depending on the voltage values measured,which define the state of charge of the battery, proceed as follows:If the voltage without load is less than12.10 V, replace the battery (see op.). 5530B10).If the voltage without load is over 12.10V but less than 12.50 V, recharge the battery (see op. 5530B14).If the voltage without load is over 12.50V, the battery is efficient.If necessary, top up the electrolyte asfollows.Carefully remove the cap strip.Top up with distilled and deionized water,taking care not to allow electrolyte to splash out.768
