The location information of the selected destination is used as the destination, a route in consideration of the effective traffic regulation information received from the display data creating unit 23 is selected, and the selected route information is passed to the display data creating unit 23. The display data creating means 23 determines whether or not the route information received from the route searching means 26 is the same as the route display data currently displayed (step 512). If they are different, a new route is newly created. Display data is created and overlaid on the map display data (step 513). If the routes are the same, the route display data currently being displayed is used.

Finally, in step 514, the route display data is displayed on the map display device in an overlapping manner with the previously created traffic regulation display data.

After that, the display data creating means 23 receives time information from the time detecting means 24 at regular time intervals registered in advance in the time detecting means 24, and at each timing when the time information is received, and at the time of the own vehicle. The processing from step 501 to step 514 is repeated each time the map display range is changed due to movement. This process is continued until finally the position of the vehicle and the position of the destination match, and if they match, the process ends.
