    摘要: An information center sends an OK message for a log-in and version information for a menu to a moving body terminal device. The moving body terminal device compares the version number of the menu held therein and the informed version number. If they are different, the device asks for menu update. In response to the request, the information center supplies difference data indicative of the difference between the menus of different versions to the moving body terminal device. Using the difference data, the moving body terminal device updates the menu held therein. With this arrangement, the menu used in the moving body terminal device can be effectively updated.
