Abstract
A vehicle navigation system provides a zoomed maneuver instruction view which displays a magnified view of the upcoming maneuver. Display of the zoomed maneuver instruction view is preferably related to the complexity of the road segments adjacent the upcoming maneuver. In one embodiment, the zoomed maneuver instruction view is displayed if more than N numbers of shape points are within a predetermined distance along the recommended route. In another embodiment, the zoomed maneuver instruction view is displayed if the recommended route includes an upcoming complex maneuver adjacent a road segment with more than N number of shape points. Preferably, the CPU will continue to magnify the complex maneuver in the zoomed maneuver instruction view as the vehicle and associated vehicle icon progresses through the complex maneuver.
