Abstract
A user selects as a guide route a route from among multiple routes retrieved under respective predetermined retrieval conditions. A retrieval condition under which the route selected by the user was retrieved is stored in an external memory. When a zone affecting driving is recognized along the guide route based on externally acquired information on traffic, a dynamic route that bypasses the zone affecting driving is retrieved according to the retrieval condition stored in the external memory. The retrieved dynamic route is then designated as a guide route.
