ABSTRACT:
A drive guide system for guiding a motor vehicle from a start point to a destination point by displaying a travel locus of the motor vehicle on a map is disclosed. A drive route map from the start point to the destination point is divided into a plurality of sections and they are stored in a memory. When a position of the motor vehicle reaches or approaches an outline of the map section displayed on a display screen, the drive route map section on the display screen is switched to the one corresponding to the direction of travel to be followed by the motor vehicle in accordance with a current azimuth of travel of the motor vehicle.
