A method for identifying a turn for a vehicle in association with a vehicle navigation system, said method comprising: determining a vehicle route having a vehicle destination; providing a video image using a camera of a scene in front of the vehicle as the vehicle is traveling along the route; automatically calibrating the camera using the video image from the camera so that the orientation of the video image relative to the ground is known; taking range measurements with vehicle mounted equipment that measures the distance from the vehicle to objects; determining a distance from a current vehicle position to a turning location along the route, where the determination includes using the range measurements; and projecting a guidance arrow onto the video image that identifies where the driver should turn the vehicle at the turning location to follow the route, wherein projecting the guidance arrow onto the display includes first placing a virtual guidance arrow laying flat on the ground at the turning location in world coordinates.
