The present invention provides a computer implemented method and apparatus for providing a display of points of interest in conjunction with a vehicle navigation system. According to one aspect of the present invention, a vehicle navigation system is provided and includes a processor configured to identify and display a plurality of points of interest with reference to a vehicle's location, and to repeat the display to reflect changes in the vehicle's location. The predetermined distance in one embodiment is determined by the vehicle speed. Filtering mechanisms are also provided wherein the displayed points of interest can be limited to user selected categories. In another embodiment, the vehicle navigation system includes a processor configured so that the plurality of points of interest identified is within a radius of the current position when the current location is within a densely digitized area. When the vehicle is not within a densely digitized area, the plurality of points of interest lie ahead along the current road within a second distance. When the vehicle navigation system is operating in navigation mode, the plurality of points lie within a third distance along the calculated route from the available points along the route. In another aspect of the present invention, the vehicle navigation system is configured to identify a plurality of points of interest using a corridor corresponding to the vehicle location.
