A navigation apparatus, including a controller that reads out map data from a memory to display a road map with link names and outputs the map data including a current position on a guidance screen. The controller monitors a drawing area for each link name and monitors a display area for the guidance screen. If a part of a link name becomes out of the display area due to scrolling, the controller moves that link name related to an amount of scrolling in a drawing direction of the link and/or displays the link name using an abbreviated link name
