Abstract
An automotive navigation system wherein a memory included therein has not stored therein picture information of an actual map but instead has stored therein geographical names and the geographical positions thereof. When the geographical names of the departure point and the destination point are entered through an input unit, a control unit reads out from the memory the respective graphical names and the positional information thereof. A display device displays marks indicating the departure point, the destination point, and the current position of a vehicle on an adequately reduced scale on the display screen. Furthermore, a display control is carried out such that the mark indicating the current position of the vehicle does not extend beyond the display screen during the running of the vehicle.
