Destination guidance in non-digitalized map area, function - GF82.61-P-4001RMU

MODEL 230.4 as of 1.7.04 with CODE (494) USA version 

On journeys outside the digitized map area (e.g. company premises, multi-level car parks, paths across fields, etc.) but still within the digital versatile disk (DVD) map borders, the navigation processor (N41/1) switches over to "navigation in the non-digitized area" The following message appears on the COMAND operating, display and control unit (A40/3) display:

• "OFFROAD"

In addition if the vehicle is outside the DVD map limit (outside the country), the following message appears:

• "OFFMAP"

When entering "OFFROAD" mode, the road map and route information are displayed.

In both cases only basic position finding (composite positioning) takes place with rectification through the global positioning system (GPS) data. Limited destination guidance takes place while only specifying:

• Distance to the destination as the crow flies
• the direction to the destination (as arrow)

After reentering the digitized map area, the system automatically continues with "Destination guidance in digitized map area". The GPS position is used to help determine the roads on which the vehicle could be located. During this process a slight delay in the route guidance may result.

In the event of the message "OFFMAP", comprehensive navigation can be continued after loading a corresponding country DVD.
