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
