Abstract
A system of navigation for vehicles is proposed, which is provided with a device (14) for representing a road map as well as with a composite navigation apparatus (10, 11, 12) for the continuous instantaneous determination of the location of the vehicle and with a location display (16) on the representation of the road map. Deviations of the location from the course of the roads on the road map are detected and corrected. In order to be able to input a desired trip route (21) into the navigation system without an additional representation of the road map, prior to the beginning of the trip the desired trip route is traced by hand, using an input device (17, 18) connected to a trip route memory, with a wand (19) on the existing representation (14) of the road map, and thereby stored in the trip route memory (13). (Fig. 1).
