GF82.61-P-3011RJ Route Calculation, Function
- with CODE (498) Japan version


After the user has entered 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 in the COMAND operating, display and control unit (A40/3) uses the Digital Versatile Disk (DVD) ROM map data, the entered destination and the instantaneous position to calculate the required route. It takes into account for the calculation the roads read in from the DVD-ROM map and their attributes, such as one-way roads, bans on turns left or right, road categories etc.(where present). Here, it is possible for the user to indicate how the route should be calculated:
^ Fastest route
^ Dynamic route
^ Own selection

When selecting the "dynamic route", an FM multiplex tuner integrated in the COMAND operating, display and control unit (A40/3) automatically stores and considers during route calculation the traffic messages received by the Vehicle Information and Communication System (VICS). 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. Following route calculation, the navigation processor in the COMAND operating, display and control unit (A40/3) creates a list of the streets and junctions to be driven.

This route list is used for destination guidance. The list can be displayed by calling up the "Traffic information (TI)" menu. If "Separate selection" is chosen, the following stretches can be blocked for route calculation purposes:
^ FREEWAY
^ Ferries, car shipment
^ Toll road
^ Tunnel
^ TOLL

Toll roads are highlighted in color on the map.

Route updating
If the driver deviates from the calculated route, the navigation processor of the COMAND operating, display and control unit (A40/3) calculates a new route list. When doing so, the current position and the direction of travel are taken into consideration. The message "New Route" appears on the display of the COMAND operating, display and control unit (A40/3) and "NEW RTE" appears on the instrument cluster (A1).

Trips outside the digitized map area
If the vehicle leaves the digitized DVD map area (e.g. driving into a multilevel car park), then no route can be calculated or updated. "OFF ROAD" is shown on the display of the COMAND operating, display and control unit (A40/3). 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.

Detour around traffic jams using the "Traffic jam" feature.
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 user must press the "Bypass jam" 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.
