PROBLEM TO BE SOLVED: To provide a navigator for performing path search and path guidance considering a U turn. SOLUTION: A navigation controller 1 includes a map buffer 16 for storing various kinds of data for map display and path search, a path search processing part 36 for performing path search processing, and a guidance path memory 38. The map buffer 16 has map data that associate the U-turn path of a road to an individual link and the path search processing path 36 performs path search by including also a link corresponding to the U-turn path in a search target. When a link corresponding to the U-turn path is included in the searched path, a path for U turn is set on the road. |
