A method for displaying waypoint information on the screen of a vehicle
navigation system. The method includes the steps of displaying a route on
the screen and inputting criteria which identify desired waypoints along
the route as well as the desired time to reach the waypoint. The location
of the desired waypoint along the route as a function of the desired time
to reach the waypoint in traffic conditions is determined and that
waypoint information is displayed on the screen. The method optionally
utilizes two-way communication between the navigation system and waypoint
content providers.
