Receives weather information of the planned area, and receives information on an area having difficulty in securing a driver's view when driving a vehicle such as a fog warning, a snowfall warning, or a heavy rain warning in an area on a driving route.

The controller 307 generates road guide information based on the matched map information, and outputs the generated road guide information to the display unit 305 and the voice output unit 306. Here, the voice output unit 306 may be a speaker.

In addition, the controller 307 may change the driving path change signal detected by the path change detection unit 309, the amount of light detected by the light amount detection unit 302, and the driving path change information received through the communication unit 308. Therefore, certain areas on the driving route are displayed brighter than the surrounding areas. The brightly displayed area may be in a left / right or straight direction on the current driving path of the vehicle at night, and may be in a tunnel, in heavy snow, or in heavy rain. As such, when there is a difficulty in securing a driver's vision in a state such as a driving route changing area or bad weather, the corresponding area is displayed brighter than the surrounding area so that the user can quickly recognize the information about the driving route changing area.

The controller 307 is a map background data identifier indicating a change area of map background data, a map search data identifier indicating a change area of map search data, and a road network indicating a change area of a road network based on the updated area information. Generates graphical information including one or more of the identifiers.

The map background data identifier is an identifier indicating an area where the background is changed in the map data and means an identifier indicating that the background of a specific area is changed due to the construction or demolition of a building. The map search data identifier is an identifier for searching a map, and means an identifier indicating that map search data of a specific region is changed due to a point of interest (POI), a change of address, a change of a phone number, and the like. The road network identifier refers to an identifier indicating that a road in a specific region has been changed due to the establishment of a new road, the closure of a road, a road under construction.

In addition, the controller 307 may include one of a map background data identifier indicating a change region of the map background data, a map search data identifier indicating a change region of the map search data, and a road network identifier indicating a change region of the road network. The above may be displayed on the screen by any one or more of a color, an icon, an avatar, a pattern, and a symbol.

The display unit 305 receives the graphic information and displays the received graphic information on the screen. The display unit 305 may be a touch screen.

Thereafter, the controller 307 determines whether at least one of the background data identifier, the search data identifier, and the road network identifier in the graphic information is selected by the user. 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. "
