摘要： A navigation device includes a GPS receiver, map data including tunnel data and periodically acquires a vehicle's speed to provide guidance on the current position N acquired at the GPS receiver, and when GPS radio waves become unreceivable after the vehicle passes a tunnel entrance, calculates a travel distance according to a vehicle speed and a time T up to a branch, and continues providing guidance on the current position up to the branch. After passing the branch, the navigation device suspends guidance, calculates a distance La between the branch and a tunnel exit, which is shorter, and when GPS radio waves are not received even after a movement distance from the branch exceeds distance La, after passing the branch, determines a road whose distance is longer as the road being traveled, and provides guidance on the current position.

摘要： A route guidance device configured so as to be freely attachable and detachable with respect to an in-vehicle device includes a route acquiring part that acquires a vehicle route calculated based on vehicle map data and acquires a pedestrian route calculated based on the pedestrian map data; and a display that outputs the vehicle route and the pedestrian route acquired by the route acquiring part. The route acquiring part, when the route guidance device has been detached from the in-vehicle device, acquires a pedestrian route calculated based on a destination having been set to acquire the vehicle route before detachment, or when the route guidance device has been attached to the in-vehicle device, acquires a vehicle route calculated based on a destination having been set to acquire the pedestrian route before attachment.
