CONSTITUTION: A key input part(214) receives a searching word. A memory part(202) stores a search-failed searching word among inputted searching words. A communications part(212) transmits the search-failed searching word to a remote navigation server through a communications network. A control part stores the search-failed searching word to the memory part when a searching is failed after executing a search for the inputted searching word. The control part(206) transmits the search-failed searching word to a remote place navigation server through a communications part. |
