Troubleshooting
Solution
The GPS signal can be blocked by heated windscreens or
tinted windscreens with a vacuum-metallised surface. In this
case, you will need an external GPS antenna. (available from
accessory dealers, Article-no. MA2010/00)
Make sure that the GPS antenna on the top of the naviga-
tion system is not obstructed by other objects.
Always keep the navigation system positioned vertically. If
necessary, you can pivot the GPS antenna upwards to im-
prove the reception.
If the navigation systems stops responding to your actions,
you can press the reset button on the underside of the de-
vice (e.g. with a straightened-out paper clip or another
sharp object). The data you have saved will not be lost! Re-
start the navigation system by pressing the normal on/off
switch.
Make sure that the battery is fully charged and/or that the
device is connected to a power source. If you are using the
DC cable, check that the plug is securely and correctly con-
nected to the cigarette lighter.
In the case of extremely low or high temperatures, the sys-
tem will temporarily shut down to prevent itself from being
damaged. It will switch itself on again once the temperature
has returned to normal.
Check whether the volume is set to an audible level in the
basic settings.
A level of inaccuracy of 50 m is within acceptable limits. If a
higher level of inaccuracy occurs repeatedly, please contact
an authorised specialised dealer.
instruc-
It may be the case that the position determined by the nav-
igation system is at the moment incorrect. The current traf-
fic situation may have changed and therefore does not
correspond to the information on the map.
