ABSTRACT:
In a map display system for vehicles, spot coordinates are preliminarily stored which represent map forming spots and are provided with a coordinate origin of a specified spot, and display coordinates indicating map changing frames are also preliminarily stored. The display coordinate of the present position of the vehicle is compared with the display coordinate of a map changing frame. When the present position reaches the map changing frame, the spot coordinate of the present position is compared with the preliminarily stored spot coordinates so as to extract spots forming a new map centering the present position of the vehicle.
