Abstract: In an off-road region such as river banks or mountainous region where no roads are present, route guiding is provided in a vehicle based on an off-road route computed without using map data. An objective point, passing points, and a departing point are designated and then connected therebetween using line segments to thereby compute the off-road route. The off-road route, a current position of the vehicle, or the like are displayed. The off-road route becomes unavailable when an obstructing cause that obstructs passing of the vehicle occurs. The obstructing cause includes falling rocks or inundation due to floods. When information relating to the obstructing cause is received from an information center or an information transmission device, a bypassing point is newly designated to thereby compute a route that bypasses the obstructing cause.

Abstract: A present time indicated by an internal clock A can be changed by an ECU. When a user inputs a starting position and a destination through a remote controller, the ECU computes an arrival time at the destination and displays the arrival time along with the present time on a touch display. Thereafter, when the user commands changing the present time, the ECU changes the present time indicated by the internal clock A by a given commanded period. The arrival time is simultaneously changed by the given commanded period.
