After commissioning, a calibration journey is required. During the jour-
ney, the speed signal (GAL) is automatically adapted to the vehicle-spe-
cific 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.

If, even after a relatively long period of time, the display with the re-
quest 

CALIBRATION RIDE CAN START!

 does not appear, then 

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
journey.

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