Abstract
A display system for use with a route guidance system includes a display displaying a proximity indicator. The proximity indicator generally comprises a bar graph which is reduced in size as the vehicle approaches the next maneuver recommended by the route guidance system. Later, the reduced bar graph changes color and flashes to signal the impending turn.
