Rear Side Window Antenna; Xm™ Satellite Radio Antenna System - Chevrolet 2008 Tahoe Owner's Manual

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite radio
signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy foliage,
bridges, garages, or through tunnels could cause loss
of the XM signal for a period of time. The radio may
display NO XM SIGNAL to indicate interference.

Rear Side Window Antenna

Your AM-FM antenna is located in the passenger rear
side windows. Make sure the inside surfaces of the rear
side windows are not scratched and that the lines on
the glass are not damaged. If the inside surfaces
are damaged, they could interfere with radio reception.
Notice: Using a razor blade or sharp object to
clear the inside of the rear side windows may affect
radio reception or damage the rear window
defogger. Repairs would not be covered by your
warranty. Do not clear the inside of the rear
side windows with sharp objects.
3-126
Notice: Do not apply aftermarket glass tinting with
metallic film. The metallic film in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
antenna due to metallic tinting materials will not
be covered by your warranty.
Because this antenna is built into the rear side windows,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose to add an aftermarket cellular telephone
to your vehicle, and the antenna needs to be attached to
the glass, make sure you do not damage the grid
lines for the AM-FM antennas or place the cellular
telephone antenna over the grid lines.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
Loading items onto the roof of your vehicle can interfere
with the performance of the XM™ system. Make sure
that the XM™ satellite antenna is not obstructed.
