ABSTRACT:
Road or other guidance is provided by displaying a structure-shape map showing building shapes and roads. Drawing of building shapes on the map is restricted according to a specific condition, e.g. the travel condition of the vehicle, or the screen scroll mode, by setting the display color for building shapes to the same color as that for a background, or by not drawing any of them, thereby preventing the screen from becoming difficult to see even during scrolling. For the structure-shape map, a storage device (3) stores map data having a name and a coordinate string for each shape of various structures and information belonging to each structure. A guidance controller (4) decides colors, color densities, patterns thereof, etc. for shapes as display modes on the basis of information belonging to the structures, e.g. the classification and height of each structure, and other detailed information (e.g. scale of construction), retrieves information belonging to a structure concerned, together with information regarding surroundings, and displays, on a display (12), shapes and names according to the decided display modes, thereby giving guidance. The structure-shape map may be displayed centered on a structure having a telephone number retrieved by entry of the telephone number.
