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 a departure point, a destination point and one or more passing points are entered through an input unit, a control circuit reads out the respective positions of the points from the memory. The control circuit controls a display unit to display on a display screen marks respectively indicating two or more of the points and the current position of a vehicle.
