Abstract
In a separate-window-display map search-and-display unit, where a current position or a cursor position arrives at a predetermined area near the outer circumference of a screen image during cursor-moving map scroll display is performed, a map-display-scale calculation unit calculates a wide-area map on a predetermined scale for displaying the current position and the cursor position on the same screen and a two-point-display map-search display searches for and displays a predetermined map. A separate-frame-window-display detailed-map search-and-display unit displays a current-position-centered detailed map and a cursor-position-centered detailed map in separate-frame windows.
