Pontiac 2004 Bonneville - Manual (Page 229)

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.
If, when you turn on your rear window defogger, you
hear static on your radio station, it could mean that
a defogger grid line has been damaged. If this is true,
the grid line must be repaired.
If you choose to add an aftermarket 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 antennas or place the cellular
telephone antenna over the grid lines.

System
Your XM™ Satellite Radio antenna is located on the

snow and ice build up for clear radio reception.
