PROBLEM TO BE SOLVED: To inform a vehicle of a current position of a moving body with high accuracy even if the vehicle is present in an environment in which a GPS signal cannot be received.;SOLUTION: A current position is measured based on the GPS signal. A vehicle mark PM for indicating the current position is displayed, and overlapped with a neighbor map. Attribute information on a succeeding link with respect to a current link is read. On the assumption that the receiving sensitivity of a satellite signal to the succeeding link is low in an area, the current position based on the GPS signal is not used, and the vehicle mark PM is continuously displayed on the neighbor map without interruption according to the autonomously-estimated current position after transition from the current link to the succeeding link occurs.;COPYRIGHT: (C)2011,JPO&INPIT
