During the journey, 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 navigation system is only ready for operation on completion of the calibration journey. Final precision is only achieved after a further journey. · The adjacent display appears after the language installation. !!P 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. Adequate GPS reception must be ensured for the calibration ride. 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 calibration will increase. $! \ % Subject to correction and technical modifications 43 Copyright by Becker GmbH, D-76303 Karlsbad Installation guide If, even after a relatively long period of time, the display with the request !does not appear, then you should check the GPS reception conditions again (as under Service Mode in the Section Function test of GPS antenna ( )46). As soon as the display with the request !appears, the calibration ride can be started. A calibration ride can also be performed in a non-digitised area.
