A vehicle navigation system is presented for performing guidance along route which produces an intersection image upon controlling a drawing area of the intersection image on the basis of information and route regarding the intersection existing on the route which requires guidance. The navigation system display control unit determines the drawing area of the intersection image on the basis of map information stored in a memory, route information stored in a route memory and information concerning an intersection requiring route information and guidance prior to producing the intersection image. In addition, the display control unit judges whether the intersection which requires route guidance is larger than the predetermined limited scale rate, and if the intersection which requires guidance is larger than the predetermined image limit, the display control unit controls a display area by reducing the scale rate so as to be able to display the entire intersection or otherwise controls the display area so as to be able to display all routes within its intersection.
