Abstract

A one-day schedule data representing a plurality of destination information each including a location of a destination and its scheduled arrival time is stored in advance in a nonvolatile RAM of a controller. As a vehicle moves, the controller selects, at predetermined time intervals, the destination information of the destination having the scheduled arrival time closest to the present time among the destinations that have not been reached yet.
