In this case, the service device 100 may use the latest version of the map data owned by the service device 100 and the terminal device. By comparing the versions of the map data embedded in the 200, the updated layer data list is extracted, and the extracted updated layer data list is transmitted to the terminal device 200 as a map update information response (S220). Here, the updated layer list means a layer data list to be updated in the map data of the terminal device 200 based on the latest version of the map data. In this case, the latest version information of the map data, that is, the latest version information of the map data which is a reference of the update layer list may be transmitted together.
