The RADIONAV radio navigation system incorporates the radio and CD Audio and CD MP3 player

  See E3510 RADIO 

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   See E4090 NAVIGATOR

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.

The radionavigator P20 receives a direct power supply (pin 12 of connector A) from the battery via the line for fuse F36 of the Body Computer M1;

Pin 16 of connector A is earthed.

Pins 10 and 13 of connector A receive the CAN line by which the radionavigator P20 is connected to the Body Computer M1 and the other system nodes.

The Body Computer M001 is connected to the radio controls on the steering wheel via the clock spring D047: pin 35 of connector D provides the reference earth at pin 6 of D047; pin 52 of connector D of M001 receives the signals from the buttons to the right of the steering wheel, whilst pin 50 of connector D of M001 receives the signals from the buttons to the left of the steering wheel.

The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001.

The Body Computer M001 receives an ignition-controlled (INT) power supply at pin 11 of connector E, whilst pin 9 of connector E of M001 provides the Body Computer with a reference earth.

The GPS aerial is located in P25a (stylus aerial on the roof FM1 and GPS) connected to the radio navigator by means of the coaxial cable.
