ABSTRACT:
A display method and apparatus for navigation system enables a user to easily see crowded POI icons and their positions in a small area on the map image by shifting the positions of POI icons in radial directions. The display method includes the steps of specifying POI icons on a map image within a region of a predefined region mark, forming a position rim which is a circle with a center of the region mark, displacing the POI icons within the region mark in radial directions to the position rim, displaying position marks at positions where the POI icons are located before the displacement within the region mark, and displaying lead lines each connecting the POI icon displaced to the position rim and the corresponding position mark.
