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

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

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
