A map information storage stores map information including roads, landmarks, and areas. An overlap determination unit determines whether a landmark and an area overlap with a road in consideration of a road and its width. A position changer moves the overlapping landmark and area to positions where they do not overlap with the road on width display. A changed map information storage stores map information including changed positional information of the landmarks and the areas. If the changed map information is displayed on a screen, the landmarks and the areas are displayed so as not to overlap with roads on width display.
