Land vehicle navigation apparatus includes a present vehicle position detector, a location setter for setting a pass-through point and a destination, and a route search unit for determination of a route to the destination through the pass-through point. A judgment area setter is provided for setting, with respect to the pass-through point, a judgment area that enables the user to select whether route guidance to the pass-through point is necessary. A controller provides control of the overall system while permitting the user's selection of whether the guidance to the pass-through point is necessary when the present vehicle position is within the judgment area, thereby facilitating guidance changeover to the route segment next following the pass-through point, without need to actually enter the pass-through judgment area near the pass-through point. Also disclosed is a storage medium operatively associated with the navigation apparatus, having encoded thereon one or more programs as required for such route guidance control procedures.
