Abstract
A guidance route search method in a navigation device is provided for searching for a guidance route which leads to a destination through a road that meets a user's needs. A first route from a starting point to a destination is searched for or retrieved, and intersections included in the first route are displayed in list form. When a user designates a desired intersection from the intersections included in the first route, and a travel direction of a vehicle beyond the intersection, the navigation device sets low a link cost of a road which leads from the designated intersection in the designated travel direction, and performs another route search for a route (second route) leading from the intersection to the destination. The navigation device connects the resultant second route and a portion of the first route between the starting point and the designated intersection, to provide the final guidance route.
