GPS Not Found
When you first start your unit, you will hear the
message "Signal too low". This message means that
your unit hasn't yet located a reliable GPS signal.
Check that your unit is connected and has a clear
view of the sky. If after five minutes, you have not
located a reliable signal, go to the "Support-Hotline"
section on the page 78.
Please check that:
• The unit has a clear view of the sky for
uninterrupted GPS reception. The unit cannot
calculate the route if there is no GPS reception
(for example, in a tunnel).
• The unit is charged or connected to the cigarette
lighter.
