Satellite Radio
SiriusXM Radio Service
If equipped, vehicles with a valid SiriusXM
radio 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, see
www.siriusxm.ca or call 1-877-438-9677.
When SiriusXM is active, the channel name,
number, song title, and artist appear on the
display.
SiriusXM with 360L
SiriusXM with 360L interface has enhanced
in-vehicle listening experience for
subscribers. The experience now offers more
categories and system learned
recommendations toward discovering more
personalized content.
To use the full SiriusXM 360L program,
including streaming content and listening
recommendations, OnStar Connected Access
is required. Connected vehicle services varyby model and require a complete working
electrical system, cell reception, and GPS
signal. An active connected plan is required.
Reference the SiriusXM user guide for use
and subscription information.
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.
SiriusXM Satellite Radio Service
If equipped, SiriusXM Satellite Radio Service
provides digital radio reception. 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 SiriusXM
signal for a period of time. Some cellular
services may interfere with SXM reception
causing loss of signal.
Mobile Device Usage
Mobile device usage, such as making or
receiving calls, charging, or just having the
mobile device on may cause static
interference in the radio. Unplug the mobile
device or turn it off if this happens.
Multi-Band Antenna
The roof antenna is for AM, FM, SXM,
OnStar, and GPS (Global Positioning System).
Keep clear of obstructions for clear
reception. If the vehicle has a sunroof, and it
is open, reception can also be affected.
