ABSTRACT:
A navigation system includes: a search unit that executes a search for a route from a start point to a destination; a display unit at which the route determined through the search is displayed together with a roadmap; and a specification unit that specifies a range on the roadmap. If an entrance interchange into an express highway, present on the route determined through the search executed by the search unit and the start point are contained within the range specified via the specification unit, the search unit executes a search within the range to determine a first route from the start point to the entrance interchange present within the range and also executes a search for a second route from the entrance interchange to the destination; and the first route and the second route having been searched by the search unit are displayed at the display unit.
