Important notes on the function of your navigation radio
In principle, the system is functional with poor GPS reception, although the accuracy of
the positioning may be impaired by poor or interrupted GPS reception or errors can
occur in the determination of the position, which result in incorrect position reporting.
Start-up characteristics
If the vehicle is parked for longer periods of time,
the satellites continue their orbit. After the
ignition is turned on, it may take several minutes
until the navigation system receives signals from
sufficient 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 is
located outside a digitised area. If other roads exist in this area, the navigation system
may issue incorrect messages. The navigation system assumes that the vehicle is located
on another road.
Thus the function of the system may be temporarily impaired after a vehicle has been
stationary for a longer period of time. The navigation system will operate reliably as
soon as GPS reception is again adequate.
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.
