Abstract
A navigation system includes a display which provides a 3-D perspective view. The angle of viewing in the perspective view is increased based upon the complexity of the intersection being displayed. Intersections of increased complexity are displayed at an increased viewing angle to facilitate understanding. A sky above a horizon on the display changes color based upon the time of day.
