Abstract
A navigation system and method for guiding a vehicle along a selected route of travel to a destination from a start point using a display unit. In the navigation system, a registered intersection nearest to the present position of the vehicle, present on the set route of travel and registered in a roadmap data, is used as the first intersection on the route of travel through which the vehicle is to pass. The vehicle can be guided toward the first intersection and if the driver manually triggers the system upon reaching the first intersection, the guidance process for the selected route can begin. Otherwise, the system again checks to see which of the registered intersections is closest to the vehicle, and the above process is repeated.
