Abstract
A navigation system for a vehicle is provided with a route determination process by which a road is selected and determined as a route according to a designated starting point and a driving direction. The route is indicated on a road map displayed on a screen, and stored. Further routes are automatically determined, intersection by intersection, according to the category of the road determined earlier as a route. Cancellation of the route thus determined is performed intersection by intersection and reported to a user by erasion of the route indication. The road map displayed on the screen always places the last intersection on the determined and uncanceled route at its center, thereby allowing the user to confirm the proceeding of the route determination and the route cancellation process.
