General Information
The digital road map
To plan a route to a destination address not only the current car position is needed
by the navigation system but also a digital road map is required where the
destination address itself as well as the roads leading to the destination address are
stored. This digital road map is located on the map CD you insert in your navigation
computer.
On the map CD the road network is stored as a line pattern, which means that even
extensive intersections only have one center point all roads lead to. That's why the
navigation system indicates the distance to the next turn as the distance to the center
of the intersection. Therefore the distance indications for highway exits given by the
navigation system may be different from those on the highway signs. The highway
signs refer to the distance to the beginning of the exit.

Areas with limited road information
In some areas all of the information about a road is not available on the
map CD. Thus, for example, turn off prohibitions, information on the
direction of travel in a one way street or prohibited entry into a pedestrian
zone may be missing. The navigation system will display a warning if you
drive into such an area.

The navigation system is no substitute for local traffic laws.
Always observe the road signs and motor vehicle traffic regulations.
Latest map CDs
Approximately 10–15 % of the traffic network is changing each year. Due to this
constantly changing conditions (newly built roads, traffic restrictions, etc.), a 100 %
correspondence of the digital road map with reality cannot be achieved under all
circumstances. We recommend to always use the latest version of the map CD for
navigation.
