Installation Guide
you should check the GPS reception conditions again (as under Serv-
ice Mode in the Section Function test of the GPS antenna (GPS-INFO
) 210).
As soon as the display with the request
appears, the calibration journey can be started.
START!
A calibration journey can also be performed in a non-digitised
area. The insertion of the Navigation CD is not absolutely nec-
essary after the navigation software has been installed. Without
the Navigation CD inserted, no location is displayed.
• The basic requirement for a calibration journey is: driving 200 -
300 metres in a straight line, then turning by at least 60 degrees
and then driving 200- 300 metres in a straight line again, and
turning again.
The direction you turn is of no significance. If these conditions
cannot be fulfilled due to the road or the fact that you do not al-
ways have optimum GPS reception, this will not lead to a poor-
er calibration, but will simply mean the time and distance
necessary for the calibration ride will be longer.
If the unit is switched off during the calibration ride, language
installation is requested when the unit is switched on again. Re-
installation can be skipped by pressing the

key.
