Claim One:
1. A navigation device for visualizing a roadway transition along an ascertained route course, the navigation device comprising: a position determining unit operable to determine a current location of the navigation device; a memory including roadway information including a road network database having geometric properties and elevation data associated with roads, including roadway transitions, and distinct graphic elements associated with the roadway transitions, the graphic elements including roadway signage; a display; and a data processing device coupled with the position determining unit, the memory, and the display, the data processing device operable to: ascertain a route course to a desired destination, identify a roadway transition from a first road onto a second road along the ascertained route course, ascertain the curvature and elevation for the first road and the second road based on the geometric properties and elevation data for the first road and the second road, determine a continuous arrow along the ascertained route course based on the ascertained curvature and elevation for the first road and the second road, generate a roadway transition visualization by dynamically superpositioning a first visualization layer including the distinct graphic elements and a second visualization layer including the determined continuous arrow, and present navigation information in a first operating mode and a second operating mode on the display, the second operating mode including the generated roadway transition visualization; wherein the navigation information automatically changes from the first operating mode to the second operating mode when the current location is near the identified roadway transition; and wherein the first visualization layer includes road characteristics and location information and the second visualization layer includes the ascertained route course along the identified roadway transition and the continuous arrow passing through the identified roadway transition.
