GF82.61-P-3011QM Route Calculation, Function
- with CODE (527) COMAND APS (with navigation)

The route is calculated and constantly updated by the integrated navigation processor after entering the destination on the COMAND operating, display and controller unit (A40/3). It can only be calculated within the digitized map area. The calculated route is a precondition for destination-oriented navigation.
The navigation processor calculates the route using the digital versatile disk (DVD) map data, the input destination, and the current position of the vehicle. During the calculation it takes into account the roads and their attributes read from the DVD map (e.g. one-way streets, bans on turning, road classes, etc.). It is also possible for the user to indicate how the route is to be calculated:
^ Quickest route
^ Shortest route
^ Dynamic route
^ Separate selection

When "dynamic route" is selected, traffic messages received over radio (ultra-short wave (FM) or network provider) are stored using a traffic data recorder integrated into the COMAND operating, display and controller unit (A40/3) and automatically taken into consideration in calculating the route. The route is then calculated with the optimum time, in a manner similar to the "Fastest route" option. Notification that the route has been recalculated taking traffic messages into consideration, is provided.

Under "Own selection", the following stretches can be blocked from the route calculation:
^ Highway
^ Ferry
^ Toll
^ Tunnel

Toll roads are color coded on the map.

Following the calculation of the route, the navigation processor generates a list of roads and junctions to be driven along. This list of routes is drawn on for destination-oriented navigation. It may also be displayed by calling up the "Information" menu.

Route updating
When the driver deviates from the calculated route, a new route list is calculated by the navigation processor. The current position and the direction of travel are taken into consideration.

The display on the COMAND operating, display and controller unit (A40/3) shows the message "New Route" and the multifunction display (A1p13) of the instrument cluster (A1) displays "NEW RTE".

Trips outside the digitized map area
If the vehicle leaves the digitized map area (e.g. driving in a multilevel car park), then no route can be calculated or updated. "OFF ROAD" appears on the display of the COMAND operating, display and controller unit (A40/3). Upon leaving the map boundary (e.g. foreign country), the message "OFF MAP" appears. Destinations that lie outside the digitized map area cannot be incorporated into the route calculation.

Bypassing traffic tailbacks through the "Detour" function
After a tailback message via traffic radio and before the route section concerned is reached, a route calculation can be arranged which bypasses the tailback.

To do this, the "Detour" button on the COMAND operating, display and controller unit (A40/3) must be pressed and the following data entered:
^ The length of the traffic jam, including the distance to the start of the traffic jam
^ The corresponding stretch should be blocked within the detailed list of routes.
