发明名称 Navigation apparatus
摘要 In a navigation apparatus, a CPU searches for a plurality of routes from a starting point to a destination. These routes share the same starting point and the destination, but vary in their course along the way. Then for route selection, the CPU refers to position information provided by a locator to determine on which of the routes the user is now moving. In this manner, the navigation apparatus can automatically select one route from several derived through the route search.
