Abstract
Abstract A navigation system to be mounted on a vehicle for carrying out a route search and displaying the searched route. Traffic jam information and the like are obtained by an beacon receiver and an input part inputs time as a driving condition. An ECU executes a predetermined calculation based on map data of a CD-ROM and traffic jam data and to obtain a range and routes reachable within the input time and to display the same. In case of residual fuel as a condition, the reachable range by this fuel is displayed. A display of gasoline stands as information for expanding reachability is also executed. Hence, a driver can plan a driving based on these information. Also, a reachable range within 2 hours is displayed and the use of railways is guided when the driver cannot reach the destination within a predetermined time.
