Abstract
A vehicle navigation system for orally issuing route guidance, capable of changing a point at which the route guidance is issued depending on the moving situation of a vehicle. The moving situation is at least one of a number of lanes in a road being traveled, a width of a crossroad intersecting the road being traveled and a speed of the vehicle. The moving situation is detected by a moving situation detector section and based on the detected moving situation, the route guidance issuing point is changed to the optimum point for the moving situation at that time by a guidance issuing point changer of a route guide controller.
