    • A method and an apparatus for detecting a state of a removable medium installed in an electronic apparatus is provided. The electronic apparatus includes a detection device, a non-volatile storage device, a state change detection device, and a first notification device. The detection device detects a state of the removable medium and creates state data. The non-volatile storage device stores the state data. The state change detection device detects a change of the state of the removable medium by comparing state data stored during a first power-on period to state data stored during a second power-on period, where the first power-on period and the second power-on period are separated by a power-off period. The first notification device produces a first notification if the state change detection device detects the change of the state of the removable medium.

    • The navigation device of the present invention has a storage device which stores map data including link data of respective links constituting roads on a map, and statistical data including travel time (moving speed) which is determined by statistical values of traffic information collected in the past, with respect to each of the links. Then, the navigation device uses for each departure time candidate, the map data and the statistical data of collection conditions corresponding to the statuses upon passing each of the route constituting links which constitute the route, so as to obtain the travel time for each of the route constituting links. Thereafter, the travel times of respective route constituting links thus obtained are summed up, and the travel time between the departure position and the destination is obtained.
    • 本发明的导航装置具有存储装置,其存储包括在地图上构成道路的各个链路的链接数据的地图数据,以及包括由过去收集的交通信息的统计值确定的行驶时间(移动速度)的统计数据 对于每个链接。 然后,导航装置在通过构成路线的构成链路的各路径时,对每个出发时间候选,地图数据和与状态相对应的收集条件的统计数据使用,以获得每个 路由构成链路。 此后,将由此获得的各个路线构成链路的行进时间相加,并且获得出发位置和目的地之间的行驶时间。

    • An information center (5000) for collecting traffic information stores in its memory device the latest map data. Then, it is determined through a terminal device (5030) whether or not history information has been recorded in a data recording medium (800) mounted in a navigation device (1000), and when it is determined that the history information has been recorded, the map data in the data recording medium are updated to the latest map data. The data recording medium (800) is removable from the navigation device (1000). Statistical traffic information may be updated along with the updating of the map data. Further, when history information is directly uploaded to the information center, an identifier is attached to the uploaded information.
