This technology can be internationalized by using the maps and data from the U.S. or Europe to develop the functions suitable to local users. It is also possible to navigate in different countries, display multiple languages in texts and provide guidance with different spoken langages. The core technological modules for dynamic navigation can be developed into an application programming interface so that vendors can develop their only GUIs on the top. This allows for rapid development of navigation systems. The core technology elements include map processing and display, location inquiries, agenda planning and setups, route searching and instructions, satellite information processing and display.
