PROBLEM TO BE SOLVED: To provide a path-guiding device for mediating the order of priority between the presentation of a course by an ETC(electronic toll collection) system and that by the path-guiding device according to the position of an own vehicle. SOLUTION: When a toll road driving discrimination means judges that a vehicle is driving on a toll road 40, an exit charge point arrival distance calculation means calculates distance D up to an exit charge point 41 of the toll road that the vehicle is driving from an own vehicle position 42. On the other hand, when the vehicle is driving ahead of a position that is in front of a road-side antenna 9 for prior prediction of an ETC system by an installation prescribed distance X, a course presentation prohibition means ahead of a charge point prohibits the presentation of a course ahead of the exit charge point of the toll road by a course presentation means. Then, the vehicle approaches the exit charge point 41 within the range of the installation prescribed distance X of the ETC road-side antenna 9, the prohibition of the presentation of courses ahead of the exit charge point of the toll road concerned is canceled by the course presentation prohibition means ahead of a charge point when no signal for indicating that information is being presented from a vehicle-mounted equipment side for ETC system is inputted to an input terminal. |
