signals, their number and fi eld
strength are displayed. The GPS
antenna must be aligned so that
it receives at least 4 satellites
and the fi eld strength is greater
than 40.
Direction
(test of the reversing
light signal): If you connected the
reversing signal, "

15 km) or manually on an exactly
measured distance (100 to 500 m)
(see p. 80).
To calibrate the device:
Switch on the vehicle ignition.
Install the navigation software
(see p. 46).
Keep the navigation CD in the
CD drive.
In the Settings menu, select
