Automotive navigation system
 An automotive navigation system wherein a memory included therein has not stored therein a picture information of a map itself but instead has stored therein geographical names and positional information thereof. When the geographical names of a departure point and a destination point are entered through an input unit, a control unit reads out from the memory the geographical names and the positions of the points. A CRT displays marks respectively indicating the departure point, the destination point, and the current position of a vehicle on an adequately reduced scale on the display scope. The arrangement of this automotive navigation system can perform a fully practical navigation function even with a small sized and cheap memory and arithmetic unit.
