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.
