A display method and apparatus for navigation system enables a user easily see a list of points of interest (POIs) along a route to a destination. The navigation system shows a list of distance ranges of the route where each range shows a number of POIs searched. The current user position is marked in the corresponding distance range. The navigation system displays a list of POI names in the selected distance range where the POI names are arranged in the order that the user sees the POIs along the route. For determining the listing order, the navigation system uses a plurality of region circles having their centers on the route to the destination, and retrieves POIs contained in the region circles and calculates a modified distance of each POI.
