3234391 - E4090 NAVIGATOR - Description

Description

The navigation system informs you of the vehicle's position on the map (in relation to both urban and non-urban/motorway road networks).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.The navigator is incorporated in the radio unit: it is a BOSCH radio navigator personalized especially for ALFA ROMEO.

The navigation system uses the GPS (Global Positioning System) satellite location technology; it has the following functions:

• vehicle location
• calculation of the route
• identification of 'route guidance' manoeuvres
• management of the map data base (on CD-ROM)

The navigation CD-ROM reader is located in the radio unit itself.

the 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 antenna is mounted at the rear of the roof: it has two functions (GSM/GPS) as it also incorporates the GSM aerial where the CONNECT  See E4091  CONNECT system is also fitted. 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 monochromatic display in the centre of the radionavigator.

When the vehicle is new or after any operation on the navigation system, the test and calibration procedures must be carried out as indicated in  Characteristic of working principle 5570  ACCESSORIES .

On the CONNECT version with a NAVIGATOR it is not possible to have a direct connection between the radio and the GSM/GPS aerial. A special GSM BOX, located in the glove compartment, is fitted to act as an electronic interface. For more details  Characteristic of working principle 5570  ACCESSORIES .
