Abstract
The invention pertains to a navigation system, for example, for a motor vehicle, as well as to a method for simultaneously displaying isolines and a road map. The navigation system comprises a processor as well as a display device for displaying a road map. The invention is characterized in that the processor is designed for selecting isoline data and for displaying isolines (1, 2, 3, 4 . . . ) on the display device, wherein the illustrated road map and the isolines that correspond to the illustrated road map can be superimposed on the display device. The invention allows a much better and intuitive orientation for the user with the aid of the expanded illustration on the monitor of the navigation system. The method and navigation system ensure a technically robust combination of existing road maps and separate isoline data, namely of any arbitrary origin, which can be realized in a cost-efficient fashion.
