  • detecting, by using a central processing unit, activation of a map scrolling operation of the navigation system;

    checking whether there is any limit condition attached to icons or map elements as to remove them from the map image;

    scrolling the map image toward a specified direction while removing the icons or map elements to which the limit condition is attached from the map image during a transition period of the map scrolling operation;

    detecting that the map scrolling operation is paused when a time length of each temporary stop of the map scrolling operation is shorter than a predefined pause time;

    reviving, when the map scrolling operation is paused, the icons or map elements that have been removed from the map image by representing the revived icons and map elements with simplified marks of identical shape on the map image; and

    displaying all of the icons and map elements of original images at a location on the map image where the map scrolling operation is completed where the scrolling operation is completed when a time length of a stop of the map scrolling operation is longer than the predefined pause time.
