ABSTRACT:
To facilitate the operation of an in-vehicle navigation system and to shorten the time required for the otherwise time-consuming entering of the destination by crosshairs by reducing the operating steps required, a general map and an enlarged portion of the general map are displayed simultaneously on a screen. A navigation computer calculates the routes. Map data from general maps and detail maps are stored in a memory. A main computer calculates the portion selectable for example by crosshairs and shown on an enlarged scale, from the data stored in the memory. The general map and the enlarged portion can be moved synchronously with one another on the screen by a graphic control unit.
