Abstract: A communication terminal transmits a route search request for a destination to a server device and obtains a route searched from the server device. The terminal requests the server device for guidance information after starting up the communication terminal, the guidance information being used to provide movement guidance for a mobile unit and being targeted for at least an update target area around a current location among update target areas, the update target areas being areas whose terminal-side map information included in the communication terminal is an older version of map information than device-side map information included in the server device. The terminal receives the guidance information transmitted from the server device in response to the request for the guidance information, and provides movement guidance for the mobile unit using a guidance route set on the communication terminal and the received guidance information.

Abstract: A communication terminal is connected to a server and provides movement guidance for a mobile unit based on guidance information delivered from the server. The terminal requests the server for update information for updating area identification information that identifies a section corresponding to an update target area and a section not corresponding to the update target area on a section-by-section basis. The update target area is an area whose terminal-side map information included in the communication terminal is an older version. The terminal updates the area identification information based on the update information transmitted from the server, requests the server for guidance information for providing movement guidance for the mobile unit based on the updated area identification information, and provides the movement guidance for the mobile unit based on the guidance information delivered from the server.

Abstract: Movement guidance devices and programs provide movement guidance for a mobile unit using guidance information for providing movement guidance for the mobile unit. The guidance information is delivered from a server device. The devices and programs store the guidance information delivered from the server device in a memory. The stored guidance information is area-section-by-area-section guidance information. The devices and programs set a remaining priority for the stored guidance information on a per area section basis of map information and delete, from the memory, guidance information for an area section with a low remaining priority on a priority basis rather than guidance information for an area section with a high remaining priority among the stored guidance information.
