Abstract
A feature provided by a navigation system to provide guidance to a driver of a vehicle. The feature comprises multiple progress bars displayed on a display screen of the navigation system. The multiple progress bars feature is displayed when the vehicle is approaching a location at which a maneuver, such as a turn, onto a road is to be made and another road is close by and might be confused with the road onto which the maneuver should be made. One of the multiple progress bars represents the vehicle's approach toward the road onto which the maneuver should be made and the other of the multiple progress bars represents the vehicle's approach toward the road not to be taken. As the vehicle approaches both roads, the progress bars are updated indicating the vehicle's relative approach to both the road onto which the maneuver should be made and the road not to be taken. The multiple progress bars feature provides meaningful information to the driver in a clear and unambiguous way thereby assisting the driver to make the proper maneuver.
