ABSTRACT:
A vehicle is guided to a lane that the vehicle should run, even if map data do not include lane information of a tollgate.A navigation processing part100makes a vehicle running path calculation part112calculate a running path of the vehicle from a point of a prescribed distance from the tollgate until an ETC receipt signal receiving part114receives an ETC receipt signal. Then, the navigation processing part100calculates an approximate position of an ETC lane on the basis of the running path, and accumulates the calculated approximate position in a storage unit. Further, when the vehicle approaches to the tollgate within a prescribed distance from the tollgate, the navigation processing part100obtains the approximate position of the ETC lane of the tollgate from the storage unit, and displays the approximate position through a display processing part106, to guide the user to the ETC lane.
