    • The present invention provides, in a car navigation system, a unit of notifying a user of the update contents of map data prior to the downloading of the map data. A vehicle-mounted terminal sets a difference update area in accordance with a selection made by a user and sends a difference update request to a map updating server. If an update mode in this case is “update after outline display”, the vehicle-mounted terminal downloads an outline update map from the map updating server. The outline update map is displayed on a display unit of a display. Here, when a download start button displayed on the display unit is depressed, the vehicle-mounted terminal downloads a detailed update map from the map updating server. The detailed update map is then displayed on the display unit of the display. Furthermore, an updating process is performed on the map data stored in a terminal DB.
    • 本发明在汽车导航系统中提供在下载地图数据之前向用户通知地图数据的更新内容的单元。 车载终端根据用户进行的选择来设定差异更新区域,并将差分更新请求发送给地图更新服务器。 如果这种情况下的更新模式是“轮廓显示后更新”,则车载终端从地图更新服务器下载轮廓更新映射。 轮廓更新图显示在显示器的显示单元上。 这里,当按下显示单元上显示的下载开始按钮时,车载终端从地图更新服务器下载详细的更新地图。 然后将详细的更新图显示在显示器的显示单元上。 此外,对存储在终端DB中的地图数据执行更新处理。
