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 rear
shelf of the vehicle.
• Satellites are being repaired or
improved.
• After-market glass tinting has
been applied to the vehicle’s
rear 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
Problems with Route Guidance on
page 75 and If the System
Needs Service on page 75.
