Radio Reception; Multi-Band Antenna - Buick Enclave 2008 Owner's Manual

Radio Reception

Frequency interference and static can occur during
normal radio reception if items such as cell 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.
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 your radio.
FM Stereo
FM stereo gives the best sound, but FM signals only
reach about 10 to 40 miles (16 to 65 km). Tall buildings
or hills can interfere with FM signals, causing the
sound to fade in and out.
3-120
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 through tunnels could cause loss
of the XM™ signal for a period of time. The radio
may display NO XM SIGNAL to indicate interference.

Multi-Band Antenna

The multi-band antenna is located on the roof of your
vehicle. This type of antenna is used with the AM/FM
®
radio, as well as OnStar
Service System, if your vehicle has these features. Keep
this antenna clear of snow and ice build up for clear radio
reception. If your vehicle has a sunroof, the performance
of the radio system may be affected if the sunroof is
open. Loading items onto the roof of your vehicle can
interfere with the performance of the radio system and,
if your vehicle has this feature, OnStar
multi-band antenna is not obstructed.
