<p>PROBLEM TO BE SOLVED: To prevent a small number of POI icons from disappearing buried under a large number of POI icons. SOLUTION: When the POI icon is displayed in a location position of a point-of-interest POI on a map in a display screen, a map image drawing part 15b generates POI icon images in order starting from an icon type in large in the POI icon number to be overwritten in a memory 15d, a map reading control part 15e takes out from the memory an image corresponding to one screen in response to a vehicle position, and displays the POI icon in the POI locating position of the map on the screen.</p> |
