A vehicle navigation system provides information relating to a list of intersections or other points of interest located ahead of a vehicle relative to a heading vector of the vehicle. The vehicle navigation system uses information about the current location of the vehicle and the heading vector in connection with a navigation database to identify a list of the intersections or other points of interest along the current street. The vehicle navigation system presents this information to an occupant of the vehicle. As the vehicle progresses and makes turn maneuvers, the navigation system updates the list of intersections or other points of interest that the vehicle is approaching. The occupant can receive information regarding points of interest without needing to enter a planned destination beforehand. In addition, the occupant can determine the location of the vehicle relative to the surrounding area without the clutter of irrelevant map details.
