subscription can receive
SiriusXM programming.
SiriusXM radio has a wide
variety of programming and
commercial-free music, coast
to coast, in digital-quality
sound. In the U.S., see
www.siriusxm.com or call
1-888-601-6296. In Canada,

content.
To use the full SiriusXM 360L
program, including streaming
content and listening
recommendations, OnStar
Connected Access is required.
Connected vehicle services
vary by model and require a
complete working electrical
system, cell reception, and
GPS signal. An active

Radio Reception
Unplug electronic devices
from the accessory power
outlets if there is interference
or static in the radio.
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. 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.
