How does the navigation system work?The position and movements of the vehicleare recorded by the navigation system’ssensors. The distance travelled is deter-mined by the vehicle speedometer signal,rotary motion in bends is detected by agyro sensor (inertial compass). The positionis determined via the GPS (Global Posi-tioning System) satellites.The position can be calculated within arange of approx. 10 m by comparing thesensor signals with the digital map on thenavigation CD.Important notes on the function of your navigation radioIn principle, the system is functional with poor GPS reception, although the accuracy ofthe positioning may be impaired by poor or interrupted GPS reception or errors canoccur in the determination of the position, which result in incorrect position reporting.Start-up characteristicsIf the vehicle is parked for longer periods of time,the satellites continue their orbit. After the igni-tion is switched on, it may take several minutesuntil the navigation system receives signals fromsufficient satellites for evaluation.During the start-up sequence, it is possible that the navigation system will report:“You are leaving the digitised area”. The navigation system assumes that the vehicle isnot located on a digitised road. If other roads exist in this area, the navigation systemmay issue incorrect messages. The navigation system assumes that the vehicle is lo-cated on another road.CommentsAfter transport of the vehicle by train or ferry, the navigation system may require afew minutes for exact positioning.After disconnecting the vehicle battery, up to 15 minutes may be required for exactpositioning. For this, the vehicle must be outdoors and the system must be switched onin order to receive transmissions from the GPS satellites.General information 5
