GF82.61-P-3011PM Route Calculation, Function

MODEL 203.0 /2 /7 as of 24.4.04
- with CODE (527) COMAND APS with single DVD drive (with navigation)
- up to Model Year 8

After entering the destination on the COMAND operating, display and control unit (A40/3), the route is calculated and constantly updated by the integrated navigation processor. This can only be calculated within the digitalized map areas. The calculated route is the prerequisite of the destination guidance system.
The navigation processor calculates the destination as entered and the current position in the route with the aid of the Digital Versatile Disk (DVD) map data. For the calculation it takes into account the roads read by the DVD map and their attributes, such as one-way streets, ban on turns left or right, road categories, etc. (where present). Here the user can determine, by which of the following methods listed the route is to be calculated:
- Fastest route
- Shortest route
- Dynamic route
- Own selection

When "dynamic route" is selected, traffic messages received over radio (ultra-short-wave (FM) or network operator) are stored in the traffic data memory integrated into the COMAND operating, display and control unit (A40/3) and automatically taken into consideration when 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:
- FREEWAY
- FERRY
- TOLL

The toll roads are highlighted in color on the map.

Following the calculation of the route, the navigation processor generates a list of roads and junctions to be driven along. This route list is used for destination guidance. 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. When doing so, the current position and the direction of travel are taken into consideration. The message "New route" appears on the display and "NEW RTE" appears in the instrument cluster (A1).

Journeys outside of the digitized map area
If the vehicle leaves the digitized DVD map area (e.g. driving in multi-level car park), it is not possible to calculate or update a route. "OFF ROAD" appears on the display. Upon leaving the map boundary (e.g. foreign country), the message "OFF MAP" appears. Destinations which lie outside of the digitalized map area cannot be taken into consideration on calculation of the route.

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 this end the "Diversion" button is to be pressed and the following data entered:
- The length of the traffic jam, including the distance up to the start of the traffic jam.
- The corresponding stretch must be blocked within the detailed route list.
