GF82.61-P-3011E Route Calculation, Function
- with CODE (353) Audio 30 APS

Once the destination is entered into the radio (A2) the route is calculated by the integrated navigation processor and constantly updated. This can only be calculated within the digitalized map areas. The calculated route is the prerequisite of the destination guidance system.

Route calculation, function
The navigation processor calculates the route based on the entered destination and with the aid of the DVD map data while constantly finding the location. In the calculation, it takes into account the roads and attributes available on the DVD card and their attributes, such as one-way streets, bans on turns, road classes, etc. (where present).

Additionally, it is possible for the operator to indicate how the route is to be calculated:
- Fastest route
- Shortest route
- Own adjustments

In the event of "OWN ADJUSTMENTS", the following stretches can be blocked from the route calculation:
- FREEWAY
- FERRY
- TOLL

After calculation of the route, the navigation processor makes up a list of the streets along the route. This route list is used for navigation. It can be displayed during navigation by pressing the "I" (INFO) and "RTE" (Route) buttons.

Route updating
If the driver deviates from the calculated route, a new route list is automatically calculated by the navigation processor. The current position and the direction of travel are taken into consideration, and the new route is optimized accordingly. This is accomplished without any message on the display.

Circumventing traffic jams with "Traffic jam" menu key function
After a traffic jam is reported on traffic radio and before reaching the affected section, a route can be calculated for driving around the traffic jam. For this purpose, activate the "Traffic jam" menu and enter the length of the traffic jam including the distance to the start of the traffic jam.

The "Traffic jam" function is also available for Federal and State highways as well as for inner city areas.

Trips outside the digitized map area
If the vehicle leaves the digitized DVD map area (e.g. driving into a multi-level car park), then no route can be calculated or updated. "OFF ROAD" appears on the display. Upon leaving the map boundary, the display "OFF MAP" appears.

Destinations which lie outside of the digitalized map area cannot be taken into consideration on calculation of the route.
