me
COMAND continuously calculates the location of the vehicle with the aid of the following procedures:
GPS position finding
Basic position finding (compound position finding)
Map-supported position finding (map matching)
The navigation computer calculates the most probable position by continuously comparing the position-
finding results returned by these three methods.
Route calculation
The route is calculated by the navigation processor after entering the destination, or automatically, after a
deviation from the suggested route has taken place.
In the dynamic destination-finding system the route calculation is automatically influenced by the
incorporation of traffic information, free of charge via RDS, TMC or over an external provider TCS by
telephone (chargeable).
The calculated route is stored in the navigation processor .
Destination-finding system
Destination finding is started once the navigation computer has performed the destination calculation.
Three display options are available for graphical representation of the destination-finding system:
1. with map
2. with map and symbol display before turn-off point
--> MIX mode
3. with symbol display only (route guidance symbols)
Any of the three methods can be used. The destination-finding system is also supported by voice output from
the vehicle loudspeakers.
