An automotive navigation system is described comprising: a running distance detecting means for detecting the running distance of a vehicle, a vehicle heading detecting means for detecting the heading of the vehicle. A display means enables a planar display based on the two dimensional Cartesian coordinates system; a storage means for storing information comprises a geographical name and the positional information for each point; and a control means for designating the geographical names of a departure point, a destination point, and at least one passing point along the path of the vehicle, reading out the positional information from storage means of the designated geographical names, and receiving signals from the running distance detecting means and the head detecting means. The control means further includes means for alternatively computing coordinates on the display of marks indicative of two or more of the departure. Destination, and passing points and a mark corresponding to the current position of the vehicle on the basis of mutual positional relationship and in a reduced scale determines the two or more points, respectively, and controls the display means to display the marks at the computed coordinates.
