Black plate (77,1) Cadillac Escalade EXT Owner Manual - 2011
Infotainment System 7-77
The GPS shows the current position
of the vehicle using signals sent by
the GPS Satellites of the United
States Department of Defense.
When the vehicle is not receiving
signals from the satellites, a symbol
appears on the map screen. Refer
to Global Positioning System (GPS)
on page 7‑76.
This system may not be available or
interferences may occur if any of the
following are true:
. Signals are obstructed by tall
buildings, trees, large trucks,
or a tunnel.
. Objects are located on the front
dash of the vehicle.
. Satellites are being repaired or
improved.
. After-market glass tinting has
been applied to the vehicle's
windshield.
Notice: Do not apply after-market
glass tinting to the vehicle's
windows. Glass tinting interferes
with the system's ability to
receive GPS signals and causes
the system to malfunction.
The window might have to be
replaced to correct the problem.
This would not be covered by the
warranty.
For more information if the GPS is
not functioning properly, see Vehicle
Positioning on page 7‑77 and
Problems with Route Guidance on
page 7‑78.
