Abstract
A map output device is provided for preventing a storage medium from being sharedly used. The map output device comprises a connection unit; an output unit that outputs map data; and a control unit. The control unit is configured, when a storage medium is connected to the connection unit or when a movable body is used beyond a predetermined usage amount, to write a file containing information on a unique value related to the movable body into the storage medium connected to the connection unit, and to output, to the output unit, the map data read from the storage medium.
