Abstract: PROBLEM TO BE SOLVED: To enable the driver of a vehicle carrying a navigation system to safely drive the vehicle on a set route by causing the driver to instantaneously recognize whether or not the vehicle properly runs on the route. SOLUTION: When the driver of an automobile automatically or manually sets the running route of the automobile to an arbitrary destination from an arbitrary starting point based on map data read out from a map information recording medium, a navigation system displays the set running route and the present location of the automobile obtained by means of a positioning means such as the GPS receiver, etc., together with map information containing the peripheral roads and crossings composed of map data. The CPU of the navigation system only extracts a crossing node group of the road list of the set route (step 301) and the road node group having coincident coordinates with those of the crossing node group of peripheral road data containing the set route (step 302).  Then the CPU replots a link which is derived from the road node group and does not contain the set route in a color specified by a map until the link reaches a fixed distance or longer.
