Digitized CD-ROM map area:

 Vehicle position within the digitized CD-ROM map area

Non-digitized CD-ROM map area:

 Vehicle outside of CD-ROM map boundaries
("OFF MAP", foreign country)

 Vehicle position inside of CD-ROM map boundaries, however, outside of digitized map area
("OFF ROAD", company grounds, rural road,...)

 The road network shown is depicted extremely simplified

Destination guidance is the generation and output of driving recommendations, in order to guide the driver to the desired destination. Prerequisites for guidance are:

 Continuous location finding in operation
(accomplished automatically),

 destination entered and

 the route has been calculated.

The navigation processor continuously compares the data from route calculation with the data from continuous

map matching, and derives the measures for further destination guidance from these. Depending on the position of the vehicle, a distinction can be made between two destination guidance system modes (see Figure):

 Guidance within digitized CD-ROM map area.

 Limited guidance outside digitized CD-ROM map area.
