Abstract
A Point of Interest (POI) icon display method in a navigation system is described for displaying a POI icon at a POI point on a map. For every POI in a POI category, the location point and type of POI are stored. Each POI is identified on the displayed map by the same POI icon, and when a POI icon of a POI is selected, the type of POI is displayed. Accordingly, it is possible to reduce the number of POI icons, recognize the type of POI, such as the type of food of a restaurant (classified by country, such as Japanese food, Chinese food, Italian food, and French food), and provide a guide route to a desired POI quickly.
