• and
• a control circuit that individually controls the connection unit and the display,
• wherein the control circuit is configured, when the movable body is used beyond a predetermined usage amount corresponding to a travel distance of the moving body,
• to generate a file containing information on a unique value after the map data has been stored in the storage medium and store the unique value within the storage medium, the unique value being a character string, related to the movable body and version information indicating a version of the map data into the storage medium connected to the connection unit and
• to output, to the display, the map data read from the storage medium in which the file containing the information on the unique value and the version information is stored, and
