ABSTRACT:
An on-vehicle navigation apparatus in which destination coordinate data stored in a memory is erased when the distance from the present location to a destination is equal to or smaller than a predetermined value at the time the engine of a vehicle is started. The destination coordinate data will not therefore be erased while the vehicle is actually running toward the destination. The arrangement prevents display of navigation information such as the direction and distance from being stopped before the vehicle arrives at the destination.
