Backglass Antenna - Pontiac Grand Prix 2007 Owner's Manual

Backglass Antenna

The AM-FM antenna is integrated with the rear
window defogger, located in the rear window. Make
sure that the inside surface of the rear window is
not scratched and that the lines on the glass are not
damaged. If the inside surface is damaged, it could
interfere with radio reception. Also, for proper radio
reception, the antenna connector at the top-center
of the rear window needs to be properly attached to
the post on the glass.
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 backglass antenna due
to metallic tinting materials will not be
covered by your warranty.

Notice: Using a razor blade or sharp object
to clear the inside rear window may damage
the rear window antenna and/or the rear
window defogger. Repairs would not be
covered by your warranty. Do not clear the
inside rear window with sharp objects.
Because this antenna is built into the rear window,
there is a reduced risk of damage caused by
car washes and vandals.
If static is heard on the radio, when the rear
window defogger is turned on, it could mean
that a defogger grid line has been damaged and
the grid line must be repaired.
If adding a cellular telephone to your vehicle, and
the antenna needs to be attached to the glass,
make sure that you do not damage the grid lines
for the AM-FM antenna. There is enough space
between the lines to attach a cellular telephone
antenna without interfering with radio reception.
