When recognizing that a way point recognizer acquires way point information about a way point, the processor (180) makes a research section research a first research route from the current-position to the destination including a section of the first guidance route as well as the way point. Owing to this, the navigation device (100) can reset the first research route including at least a section of the first guidance route, i.e., the first research route reflecting the first guidance route, as a second guidance route even after the first guidance route is set.",
