ABSTRACT:
A communication navigation system that performs navigation, using map data stored in a map database site and current position data about navigation terminals, by transmitting the map data to the navigation terminals via a communication network such as the Internet, wherein the map data includes data units respectively corresponding to a plurality of display elements for display on a map, and the data units are given respective priority levels. The map database site is provided with a server for transmitting the data units via the communication network according to the respective priority levels. Each navigation terminal is provided with a transmitter/receiver for sequentially receiving the data units transmitted from the server, and a display subsystem for sequentially displaying the display elements respectively corresponding to the data units received by the transmitter/receiver, on the map.
