Abstract
A storage medium of a car navigation apparatus holds painted road sign information that is linked to a running lane of an approach road around an intersection. Suppose that a direction of an exit road with respect to an approach road at an intersection belongs to a peripheral portion of one of directional areas that are provided to determine at an intersection the approximate direction of the exit road with respect to the approach road. In this case, the approximate direction is specified based on the corresponding painted road sign information. The specified approximate direction is then outputted as a voice and/or image display. Thus, utilizing the painted road sign information can reduce user's disagreeable feeling to the approximate direction.
