DESCRIPTION
The RADIONAV radio navigation system incorporates the radio and CD Audio and CD MP3 player
The navigation system is equipped with:
- SD card reader
- GPS module
- independent navigation module with maps
- 6.5" TFT colour monitor
- interface with the controls on the steering wheel
|
On the version described here, the RADIONAV system is combined with the "basic" radio and therefore there is no telephone management. On other versions the RADIONAV may also be combined with the Blue&Me system: in this case the RADIONAV manages the navigation and the Blue&Me manages the Media Player and Telephone functions |
The navigation system with road maps makes it possible to determine the position of the vehicle on the map at any time (for both urban and extra-urban/motorway road networks) showing it on the radio navigator display.
In this way the driver is guided step-by-step to the required destination, by means of voice messages and visual information. The system also provides additional information for reaching general services, namely: hotels, car parks, restaurants, pharmacies, service stations, hospitals, ALFA ROMEO workshops, railway stations, airports, etc.
The navigation system uses GPS (Global Positioning System) satellite location technology and is inside the radio navigation unit.
The navigation maps are on a special SD card.
The GPS consists of an aerial that allows the vehicle to be GPS satellite-located: the aerial is connected to a receiver located in the integrated unit by means of a special shielded cable.
The stylus aerial is fitted at the rear of the roof: it performs two functions (radio and GPS) because it also incorporates the radio aerial (FM1).
Vehicle position is identified by analysing GPS data together with speedometer and reverse gear signals received from the vehicle.
The radio navigation unit is a CAN node through which information is exchanged with the Body Computer and with the other electronic units.
