Abstract:
1. A method for operating a navigation system for a motor vehicle in a road network, wherein at least one zone of the road network is provided with an emissions class-dependent drive-through restriction, wherein the motor vehicle is associated with at least one emissions class, comprising: in a first step storing in a first database of the navigation system, information about the geographic location of the one or more zones and about the minimum emissions class that is required in the zones for the motor vehicle to be authorized to drive through, in a second step, entering information about the one or more emissions classes of the motor vehicle with the navigation system in a second database of the navigation system, and in a third step, considering the information entered in the first and second steps in the destination guidance process, wherein destination guidance into or through the zone is avoided, if the one or more emissions classes of the motor vehicle are affected by emissions class-dependent drive-through restrictions in the zone, wherein in the second step, the emissions class is transmitted from a motor-vehicle-side information memory to the navigation system, wherein a mobile navigation system is used as the navigation system and information about the one or more emissions classes is read out via wireless contact by the navigation system from a vehicle-side information memory.
