After commissioning, a calibration journey is required. During the jour-
ney, the speed signal (GAL) is automatically adapted to the 
vehicle-specific data and the gyro sensor is automatically adapted 
to the installation position of the unit.
The distance to be covered depends on the type of vehicle and the local 
conditions.

The adjacent display appears after the language installation.

It is possible that GPS reception has deteriorated as a result of 
changing the vehicle position and due to obstructions. In this case, 
the adjacent display appears.

The navigation system is only ready for operation on comple-
tion of the calibration journey. The main navigation menu is
displayed. Final precision is only achieved after a further jour-
ney.

Adequate GPS reception must be ensured for the calibration
ride. This means at least 2-D FIX. With GPS FIX 3-D the cali-
bration will be quicker. However: a lower accuracy of the GPS
signal (2-D FIX) does not lead to a poorer calibration, but in-
stead will mean that the time and distance needed for the cali-
bration will increase.
