Problem
Solution
No GPS signal in vehicle
The GPS signal can be blocked by heated wind-
screens or tinted windscreens with a vacuum-
metallised coating. In this case, you will need
an external GPS aerial (available from
accessory dealers, article no. MA2010/00).
No GPS signal
Ensure that the GPS aerial on the top of the
navigation system is not obstructed by other
objects.
GPS signal poor
Attempt to adjust the navigation system.
The navigation system no longer responds
to finger taps or does not switch off
If the navigation system stops responding to
your entries, you can press the reset button on
the underside of the device (e.g. with a
straightened-out paper clip or a pencil). The
data you have saved will NOT be lost! Restart
the navigation system by pressing the power
button.
System fails to start, screen remains blank
Ensure 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 connected to the
cigarette lighter.
The system shuts down automatically after
a certain amount of time
In extremely low or high temperatures, the
system will temporarily shut down to prevent
it from being damaged. A sudden shutdown is
also possible when the battery is empty.
The voice alerts for navigation cannot be
heard
Check whether the volume is set to an audible
level in the basic settings.
Navigation is not accurate
An inaccuracy level of 50 m is within accept-
able limits. If an inaccuracy level occurs repeat-
edly, please contact an authorised specialised
dealer.
Driving/navigation instructions do not
correspond to the actual traffic situation
The position currently determined by the navi-
gation system may be incorrect. Traffic routing
may have changed and does not correspond to
the information on the map.
No sound
The device may be set to mute, or the volume
is set too low.
