A vehicle location display for a navigation or route guidance system is disclosed. The vehicle location display provides information to a user regarding the current location of the vehicle on a map even when the scale of the map is large. In a preferred embodiment, the map includes a current location field that displays a road segment name associated with the current road segment that the vehicle is located on. In an alternative embodiment, the vehicle location display displays a large scale map wherein the current road segment is highlighted by displaying it in a color and the name of the current road segment is displayed in a current location field on the map.
