Abstract
Using a mobile radiotelephone network and a traffic routing and information central as well as a navigation apparatus and a mobile radiotelephone in the vehicle, the user requests a current route in dialogue via a mobile radiotelephone network and a traffic routing and information central. The destination input ensues at any arbitrary location independently of a mobile radiotelephone connection to the central. The navigation apparatus initially calculates the route purely self-sufficiently on the basis of the stored on-board data. With an inquiry to the central, it is not the current position but the presumed position at the time of the anticipated reply to the vehicle that is transmitted, and the data of the route recommendation is forwarded to the vehicle in the form of a sequence of path segments.
