Today's navigation service does not guarantee providing up-to-date navigation information to the users. It requires that users manually update the GIS map data and the navigation application into the newest one. A new ITS platform is proposed providing automatic update of the navigation application and its map data through a wireless network. When the software starts running, the platform inspects the version of navigation application and its map data. If the application or map data are out of date, the platform automatically download the latest one and deletes the old one. The transmitted application and data are a piece of the whole but not entire. The platform breaks the software and data into several pieces that are streamed to the user as needed. Immediately on downloading the first piece of the software and data, it is executable. In this way, the platform enables software and data to be updated through slow wireless network while minimizing user perceived application load time. For the covering abstract see ITRD E134653.
