from the satellites, a symbol appears in the
status bar.
This system might not be available or
interference can occur if any of the
following are true:
.Signals are obstructed by tall buildings,
trees, large trucks, or a tunnel.
.Satellites are being repaired or improved.For more information if the GPS is not
functioning properly, see
