The location of the vehicle as well as the direction and distance to the destination (according to destination entered) is determined with the aid of the navigation system. Then the required measures to reach the destination are started (guidance).

The navigation system can be activated by pressing the"NAV" button on the radio and navigation unit (A2/56).

A navigation processor with CD-ROM drive is integrated into the radio and navigation unit (A2/56) for reading in the navigation data (digital map, speech segments and software).

The navigation CD-ROM drive can also be used to play audio CDs.

Entering destination

The destination can be entered with menu guidance on the radio and navigation unit (A2/56) and processed by the navigation processor. The system only allows entry of destination addresses stored on the CD-ROM.

The following possibilities are available for entering a destination:

Call-up of destination stored in destination memory

Free entry of destination with menu guidance based on name (when destination is stored on CD-ROM)

Location finding
The navigation processor continuously calculates the location of the vehicle with the aid of the following procedures:

GPS location finding

Basic location finding (dead reckoning)

Map-supported location finding (map matching)


The correct position is determined by continuously comparing the locating result of these three procedures.

Route calculation

The route is calculated in the navigation processor according to the destination entered, or automatically, after deviating from the recommended route.

The recommended route is stored in the navigation processor.

Guidance
After the navigation processor has calculated the route, guidance is started. The driver receives continuous information with the aid of guidance symbols appearing on the display of the radio and navigation unit (A2/56) and voice announcements on the vehicle loudspeaker.
