摘要：
A navigation system including a map data server and a navigation terminal. The map data server stores map data produced for the map information of a specific region. When an external manager modifies the map data, the server produces and transmits map modification command information corresponding to the modified map data. The navigation terminal stores map data corresponding to the map data stored in the map data server, receives and analyzes the map modification command information, and modifies the previously stored map data according to the analyzed result. Therefore, map data can be updated using the small amount of map modification command data.
