Abstract
A terminal unit (400) of a navigation system (100) transmits to a server (300) list request information containing a rectangular code corresponding to a predetermined display rectangular area of a travel route map. The terminal unit (400) acquires from the server (300) a server POI list corresponding to the rectangular code of the list request information, and when recognizing that the server POI list contains POI individual information corresponding to terminal base data that is not stored in a terminal base storage area, the terminal unit (400) transmits base data request information about POIID of the POI individual information to the server (300). Upon acquisition of server base data corresponding to the base data request information from the server (300), the terminal unit (400) stores the server base data in the terminal base storage area as terminal base data.
