PROBLEM TO BE SOLVED: To provide a technique for enabling navigation even when it is difficult to input data of either a starting point or a destination of a route or both when performing a route search and its navigation.SOLUTION: A portable terminal (30) comprises, for example: an electronic stamp (10) for executing an input of parking place data related to a parking place; communication availability determination means for determining whether or not a place where the parking place data is inputted is communicable; navigation data receiving and storing means for receiving and storing navigation data from a data server (40) when the communication possibility determining means determines that the portable terminal has moved to a communicable place in a case where it is determined that communication is impossible, the navigation data being necessary for navigation including map data around the parking place; and navigation means for executing navigation to the parking place based on the navigation data when the communication availability determination means determines that the portable terminal has moved from a communicable place to a place where a communication is impossible.SELECTED DRAWING: Figure 13
【課題】 経路検索およびそのナビゲーションをする際に、経路の始点または目的地のいずれか一方、または双方のデータ入力が困難であっても、そのナビゲーションを可能とする技術を提供する。【解決手段】 たとえば、駐車場所に関する駐車場所データの入力を実行する電子スタンプ(10)と、駐車場所データを入力した場所が通信可能か否かを判断する通信可否判断手段と、 通信ができないと判断した場合に通信可能な場所へ移動した旨を前記の通信可否判断手段が判断したら前記の駐車場所の周囲の地図データを含むナビゲーションに必要なナビ用データをデータサーバ(40)から受信して格納するナビ用データ受信保存手段と、 通信可能な場所から通信不能な場所へ移動した旨を前記の通信可否判断手段が判断したら前記のナビ用データに基づいて前記の駐車場所へのナビゲーションを実行するナビゲーション手段と、を備えた携帯端末(30)とする。【選択図】 図13
