Here, the user selects one or more of the background data identifier, the search data identifier, and the road network identifier through the touch screen, or the user through the input unit (for example, reference numeral 130 of FIG. 2). Any one or more identifiers may be selected from the graphic information.

The controller 307 is configured to provide map data corresponding to the selected identifier through the communication unit 308 when at least one of the background data identifier, the search data identifier, and the road network identifier in the graphic information is selected. Request to center 500.

The information providing center 500 transmits the updated map data requested by the controller 307 through the wireless communication network 400.

The control unit 307 receives the update map data transmitted from the information providing center 500 through the communication unit 308, and stores the received update map data in the storage unit 304. The storage unit 304 updates the map data by overwriting the updated map data.

The controller 307 may generate voice information indicating the received updated area information and output the generated voice information to the voice output unit 306. For example, the controller 307 generates voice information such as "the background of a specific area has changed" when the received updated area information indicates a change area of background data, and the received updated area information is generated. When indicating the changed area of the map search data, voice information such as "The map search data of a specific area has been changed" is generated, and when the received updated area information indicates the changed area of the road network, the "road network of a specific area" is displayed. May have changed. "
