Abstract

In order to simplify the setting of interchanges for getting on and off, a navigation system has an information retrieval processing unit for obtaining map data and interchanges for getting on and off, a display unit which displays a setup screen for displaying a map including the interchanges for getting on and off and, on the same screen, a simple road chart including neighboring interchanges for getting on and off. When the map is scrolled, the simple road chart is renewed so as to correspond to the area to which the map is scrolled, and the setting of the interchanges for getting on and off is simplified.
