GENERAL INFORMATION
Comments
After transport of the vehicle by train or ferry, the navigation system may require a few minutes for exact positioning.
After disconnecting the vehicle battery, up to 15 minutes may be required for exact positioning. For this, the vehicle must be outdoors and the system must be switched
on in order to receive transmissions from the GPS satellites.
The digital road map
To be able to plan a route to a destination address, the navigation system not only requires the current position of the vehicle but also a digital road map containing the destination address itself and the roads leading to the destination address. This digital road map is on the map CD which you insert into the navigation computer.
Real road network | Digital line model |
The road system is stored on the map CD as a line model, i.e. even large intersections have only one focal point that is approached by all roads in
Areas with limited road information
In some areas, not all of the information on a road is available on the map CD. Thus, for example,
Topicality of the map CD
Roughly 10 - 15% of the road system characteristics change each year. Due to these constantly changing traffic conditions (construction of new roads, traffic calming, etc.) we cannot guarantee that the digital road map will be in 100 % agreement with existing traffic conditions. We recommend that you always use the most current version of the map CD for navigation.
