functions.
Start-up Behavior
When the vehicle is parked for a long period of time,
the satellites move on during this period. Therefore,
when the ignition is turned on again it can take a few
minutes before the navigation system can pick up
enough satellites and evaluate the received signals.
When starting up, the navigation system may tell you:
’You are leaving the digitized area’. The navigation
system supposes the vehicle is in an off-road position.
If there are other roads in this position, the system
may send an inappropriate message. This means that
the navigation system supposes the vehicle is on one
of the other roads. When the vehicle has been at a
standstill for a longer period of time, the navigation
function may be temporarily inhibited. The system will
operate reliably again once the GPS reception is
