Black plate (59,1)Cadillac CTS/CTS-V Navigation System - 2013 - crc - 8/21/12
Infotainment System 59
At times, other interferences such
as the satellite condition, road
configuration, the condition of the
vehicle and/or other circumstances
can interfere with the navigation
system's ability to determine the
accurate position of the vehicle.
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 Symbols.
This system may not be available or
interferences may occur if any of the
following is 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 If the
System Needs Service and
Problems with Route Guidance.
