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 in 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.
