GF82.85-P-2012P Navigation Mode, Function
- with CODE (352a) COMAND operating and display system
- except CODE (491) U.S. version
- except CODE (498) Japanese version

Component Identification:

The location of the vehicle, the direction and distance to the destination (after destination entry) are determined with the aid of the COMAND navigation system. The navigation system calculates the data on how to reach the destination (navigation).
The navigation system is activated by actuating the "NAV" button on the COMAND operating, display and control unit (A40/3). In the COMAND operating, display and control unit (A40/3) there is an integrated navigation processor with Compact Disc (CD) drive for digital map data.

Note in navigation display:
- Up to 31.5.01: "Please insert Navigation CD"
- As from 1.6.01: "Please insert Navigation CD type DX"

This info is intended to ensure that the customers insert the correct CD. The multi-standard disk drive can also play audio CDs.

Destination entry (up to 31.5.01)
Entry of the destination can be performed with menu guidance on the COMAND operating, display and control unit (A40/3) and is processed by the navigation processor. The COMAND operating, display and control unit (A40/3) offers the following options for destination entry in navigation mode:
^ Address input
^ via destination memory
^ via map
^ Special destinations (e.g. railway station, airport)
^ Travel guide
^ Intermediate destination entry with individual destination designation facility

Destination entry (as from 1.6.01)
Entry of the destination can be performed with menu guidance on the COMAND operating, display and control unit (A40/3) and is also processed by the navigation processor.

The COMAND operating, display and control unit (A40/3) offers the following options for destination entry in navigation mode:
^ Address input
^ Destination memory
^ Destination with map
^ Special destinations (e.g. railway station, airport)
^ Travel guide
^ Last destinations

Entry aid (as from 1.6.01)
During entry of the destination, letters not yet entered are supplemented from a list. The entry aid relates to entry of the destination and street during navigation.
In the menu "Special destinations" the submenus "Bypassing other locations..." and "National destinations..." are assisted. The menu "National destinations..." is subdivided into a further submenu.

Dynamic supplementation
Dynamic augmentation is implemented upon manual entry of the destination. During entry of the destination, letters not yet entered are supplemented from a list. The supplemented characters have a black background. Deleting can be accomplished character by character.

Position finding
The COMAND operating, display and control unit (A40/3) continuously calculates the location of the vehicle with the aid of the following procedures:
^ GPS position finding
^ Basic position finding (dead reckoning)
^ Map-supported map matching

The navigation processor calculates the most likely position by continuously comparing the results returned by these three methods:

Route calculation
The route is calculated by the navigation processor in accordance with the specified destination, or automatically, after a deviated from the suggested route has taken place.
In the dynamic navigation system, route calculation is automatically influenced through the integration of traffic information, either free of charge via the Radio Data System (RDS) and Traffic Message Channel (TMC) or by an external provider by telephone. The calculated route is stored in the navigation processor.

Route guidance
Navigation starts once the navigation processor has carried out the route calculation. 3 types of display can be selected for graphic navigation:
^ with map
^ with map and symbol display before turn-off points
^ with symbol display only (guide symbols)

It is possible to change arbitrarily between the 3 types of presentation. The destination-finding system is also supported by voice output from the vehicle loudspeakers.
