Abstract
In a navigation device, a position measurement unit measures a current position of a movable body and generates current position information indicating the current position of the movable body. A map information storing unit stores map information. An additional information storing unit stores additional information which can be indicated together with the map information. The additional information is information useful to navigation. A control unit generates indication information including the current position of the movable body, the map information concerning the current position of the movable body, and the additional information concerning the map information related to the current position of the movable body. An indicating unit externally indicates the indication information.
