Radio Reception; Backglass Antenna - Buick LaCrosse 2011 Owner's Manual

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.
