Cadillac 2007 XLR - Manual (Page 230)

Care of the CD Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.
Diversity Antenna System
The AM-FM antennas are located under the
decklid surface in the trunk compartment. The
antennas are hidden from view and are not
accessible.
If adding an aftermarket cellular telephone to your
vehicle, do not attach the antenna to the rear
glass. This would interfere with the convertible top
retraction operation and could cause damage to
the finished/painted surfaces.
XM™ Satellite Radio Antenna
System
Your vehicle may have the XM™ Satellite Radio
antennas that are located in the outside rear
view mirrors. These antennas are hidden from
view and are not accessible.
