Abstract: PURPOSE: To enable a navigation device for vehicle to start route guidance from a pertinent location by starting route searching by setting a location a prescribed distance ahead of the present location of its vehicle along a road as a search starting point. CONSTITUTION: A route searching means 4a searches an initial route from the present location of its own vehicle to a destination or a passing point based on map information or present location information and, at the same time, again searches a route when an out-of-route detecting means 4d detects out of route, etc., and makes a route storing means 4b store the searched route.
