置。 An in-vehicle system that estimates the current location based on the vehicle's travel distance and direction, and when the estimated current location does not match the road conditions in the map information, moves the estimated current location to a suitable road to match the actual road conditions. The navigation device is configured to include matching means for performing the above matching while allowing a larger error range in direction when the road on which the vehicle is traveling is a single road than when there are multiple roads. An in-vehicle navigation device characterized by:
