Abstract
Abstract The invention relates to a map panning directional indicator for a navigation system. A display device of the navigation system displays the map panning indicator, which indicates both a current heading between a map panning cursor and a current vehicle location relative to a map database and a distance between the map panning cursor and the current vehicle location. The map panning cursor is displayed in the center of a map section as a user pans over map sections of the map database, which are displayed on the display device.
