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 part 100 makes a vehicle running path calculation part 112 calculate a running path of the vehicle from a point of a prescribed distance from the tollgate until an ETC receipt signal receiving part 114 receives an ETC receipt signal. Then, the navigation processing part 100 calculates 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 part 100 obtains the approximate position of the ETC lane of the tollgate from the storage unit, and displays the approximate position through a display processing part 106, to guide the user to the ETC lane. |
