Abstract

A motor vehicle navigation system and method uses an output device for the acoustic output of driving maneuver information and a processor device which is equipped such that a route to be traveled is determined. Driving maneuver information is determined based on the route to be traveled and on an actual position. An alternate route is computed, assuming that the determined driving maneuver information is not observed. As a function of the difference between the route and the alternate route, particularly with respect to the expected driving time, driving distance and/or driving cost, the driving maneuver information is either acoustically emitted or not.
