Method for improving route planning of navigation system installed in motor vehicle, involves transmitting additional information from navigation system directly to another navigation system

摘要

The method involves scanning position information along a track by a navigation system (110). The additional information is determined from route information in a memory card (130) of the navigation system based on the position information. The additional information is transmitted from the navigation system directly to another navigation system (160) for improving the planning in the area of the route by another navigation system. Independent claims are included for the following: (1) computer program product for improving route planning of navigation system; and (2) navigation system.
