A navigation apparatus includes a display control unit that displays a roadmap by using road data and an intersection arrangement at an intersection by using the intersection arrangement data. The intersection arrangement data include intersection coordinate data containing coordinate information corresponding to an intersection as well as display data used to display an intersection arrangement at an intersection. When approaching a specific intersection on the roadmap, the display control unit makes a decision as to whether or not the intersection coordinate data include coordinate information corresponding to coordinate information for the specific intersection on the roadmap, and if the intersection coordinate data are determined to include coordinate information corresponding to the coordinate information for the specific intersection, the display control unit judges that the road data and the intersection arrangement data match up, and displays the intersection arrangement at the specific intersection by using the intersection arrangement data.
