dashboard FORD SUPER DUTY 2008 2.G Navigation System Manual

LIMITED GPS RECEPTION
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
•In multi-story parking garages
•In tunnels and under bridges
•Inside or in between buildings
•By forests or tree-lined avenues
•In heavy rain showers and thunderstorms
•In valleys and in mountainous regions
•Roads under cliffs
Ensure that you do not have any metal objects on the dashboard and
that if your windows are tinted, they use non-metal tinting instead of
metal oxide tinting. Both of these factors can also interrupt GPS
reception.
If the vehicle has been parked for a long period of time, the navigation
function may be temporarily unresponsive. The navigation system will
operate reliably again once GPS reception is available for a few minutes.
