Navigation in non-digitized map area, function - GF82.61-P-4001BA

MODEL 215, 220 with CODE (352a) COMAND operating and display system with CODE (494a) USA version 

In vehicles as of 1.9.03, the navigation processor (N41/1) is installed as a separate control unit on the left-hand side of the trunk.

When traveling outside of the digitized map area (e.g. company grounds, parking lots, dirt roads,...), however still within the DVD map boundaries, the navigation processor switches over to "Navigation in non-digitized map area".

The message "OFF ROAD" appears on the COMAND operating, display and control unit (A40/3) display.

If the vehicle is outside the DVD map limit (outside the country), the message "OFF MAP" appears.

In both cases, only the basic position finding (compound position finding) continues to operate with correction using the GPS data.

(Limited) navigation can be conducted only with specification of the:

• Distance from the destination as the crow flies
• Direction to the destination (as an arrow)

After reentering the digitized map area, the system automatically continues with "Navigation 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 navigation may occur.

In the event of the message "OFF MAP", comprehensive navigation can be continued after inserting a relevant DVD for abroad

As of 1.9.02 the street map is faded in when the OFF-ROAD mode is entered and route information is displayed during the OFF-ROAD mode.
