Radio Reception
Frequency interference and
static can occur during normal
radio reception if items such as
cellular phone chargers, vehicle
convenience accessories, and
external electronic devices are
plugged into the accessory power
outlet. If there is interference or
static, unplug the item from the
accessory power outlet.
FM
FM signals only reach about
16 to 65 km (10 to 40 mi). Although
the radio has a built-in electronic
circuit that automatically works to
reduce interference, some static
can occur, especially around tall
buildings or hills, causing the
sound to fade in and out.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on the radio.
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 tunnels may
cause loss of the XM signal for a
period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's radio.
This interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on.
This interference can cause an
increased level of static while
listening to the radio. If static is
received while listening to the
radio, unplug the cellular phone
and turn it off.
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. For proper radio
reception, the antenna connector
needs to be properly attached to
the post on the glass.

Black plate (20,1)Buick LaCrosse Owner Manual - 2011
7-20 Infotainment System
If a cellular telephone antenna
needs to be attached to the glass,
make sure that the grid lines for the
AM-FM antenna are not damaged.
There is enough space between
the grid lines to attach a cellular
telephone antenna without
interfering with radio reception.
Notice:Using a razor blade or
sharp object to clear the inside
rear window can damage the rear
window antenna and/or the rear
window defogger. Repairs would
not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects. 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 the vehicle
warranty.
Satellite Radio Antenna
For vehicles with XM satellite radio
service, the antenna is located on
the roof of the vehicle. Keep the
antenna clear of obstructions for
clear radio reception.
Audio Players
CD Player
The CD player can play audio CDs
and MP3 CDs.
The CD player will not play
8 cm (3 in) CDs.
Care of CDs
Sound quality can be reduced due
to disc quality, recording method,
quality of the music recorded, and
how the disc has been handled.
Handle discs carefully and store
them in their original cases or other
protective cases away from direct
sunlight and dust. If the bottom
surface of a disc is damaged, the
disc may not play properly or at all.
