Abstract
A communications-type car navigation system including a vehicle-mounted terminal and a server. When transferring, to the terminal, the result of a route searching which the server has performed, the server transfers the data that will satisfy the requirements of a route guiding method which the user wishes. Also, the server transfers the route data that has been compressed. Concerning the map data as well, the server transfers only the necessary attributes thereof. Moreover, the following conditions allow the operability to be enhanced: the selection of a map transferring method and the route guiding method where the driving state has been taken into consideration, and the selection of a guiding unit which the user wishes.
