摘要： A map data utilization apparatus retrieves a version information of map data for a specific area when a current position of a vehicle is updated. Then, the version information of the map data of the specific area is compared with a version information of the map data of an identical area in a version list that is retrieved in advance for map data updating. When the version of the map data in the version list is different from the one of the map data of the specific area, an inquiry screen is displayed on a display unit for inquiring a user whether the map data is updated. When an update is instructed by the user, map data update data is acquired from an information center, and the map data of the specific area is updated by using the map data update data.
