GF82.61-P-3011QN Route Calculation, Function
- with CODE (525) MB Audio 50 APS radio


After entry of the destination at the radio and navigation unit (A2/56), the navigation processor calculates and continually updates the route. The route can only be calculated within the digitized map areas. The calculated route is the prerequisite of the navigation system.
The navigation processor calculates the route using the read-in navigation CD, the input destination, and the current position of the vehicle.It takes into account the read-in streets and their attributes such as one-way streets, turn prohibitions, and road type.

Here, it is possible for the user to indicate how the route should be calculated:
^ Fastest route
^ Shortest route
^ Dynamic route
^ Own selection

If the user selects the "Dynamic route", a traffic data recorder integrated in the radio and navigation unit (A2/56) is used to store traffic messages received via the radio; these are then automatically taken into consideration when the route is calculated. 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

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 navigation. It may also be displayed by calling up the "Information" menu.

Route updating
If the driver deviates from the calculated route, the navigation processor calculates a new route. 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).

Trips outside the digitized map area
If the vehicle leaves the digitized map area (e.g. driving into a multi-level car park), then no route can be calculated. "OFF ROAD" appears on the display. The words "OFF MAP" appear on the display when the vehicle leaves the digitized map area. Destinations which lie outside of the digitized map area cannot be taken into consideration when calculating the route.

Bypassing traffic jams
After a traffic jam message has been received via traffic radio and before the route section concerned is reached, a route calculation can be arranged which bypasses the traffic jam. To do this, the user must press the "Bypass" button and enter the following data:
^ The length of the traffic jam, including the distance to the start of the traffic jam
^ The corresponding stretch must be blocked within the detailed route list.
