Destination guidance, function 

Destination guidance includes making up and outputting driving recommendations to guide the driver to the desired destination. The prerequisites of destination guidance include:

• Continuous position finding is in operation.
• The trip destination has been entered.
• Route has been calculated.

The navigation processor (N41/1) continuously compares the route calculation data with the position finding data and derives from this the measures for continued navigation.

Depending on the position of the vehicle, a distinction can be made between the following two destination guidance system modes:

• Navigation within digitized DVD-ROM map area
• Restricted navigation outside the digitized DVD map area
