Pontiac 2004 Grand Prix - Manual (Page 236)

Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Be 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 try to clear frost or other material
from the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid and affect your radio’s ability
to pick up stations clearly. The repairs wouldn’t
be covered by your warranty.
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.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose to add a cellular telephone to your
vehicle, and the antenna needs to be attached to the
glass, be 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
Do not apply aftermarket glass tinting to the back glass.
The metallic film in some tinting materials will interfere
with or distort the incoming radio reception. Care must be
taken when cleaning the rear window because it breaks
in the resistive material heating element and will
adversely affect radio and defogger performance.
See your dealer for details.
