Additional Options (RPOs)
ONLY with Infotainment System RPOs IO3, IO4, IO5, IO6 or UI2, UI4, UI5, UI6, UI7,
UI8 (UIX programs designated above with *)
Also equipped with SiriusXM Satellite Radio (RPO U2K)
Condition
Some customers may comment on the audio muting when listening to some SiriusXM
channels, but if they change channels they will find others that experience normal audio.
They may also comment that the concern appears to happen in some geographic
locations but not others. If they experience this concern, they should continue to listen to
the currently tuned channel and observe if the condition clears after approximately 1.6 km
(1 mile).
Cause
The cause of the condition may be the result of interference from transmitting sources
outside of SiriusXM’s frequency range.
Correction
If you encounter a vehicle with the above concern, check the vehicle for any codes and
repair them as necessary.
If no codes are present and the customer is experiencing muting at the dealer’s location,
perform the following Service Procedure steps.
Service Procedure
Labor Operation
Note: The following steps are intended to be
performed in an area where muting is or has been
experienced.
1.
2.
3.
4.
Tune to SXM Channel 1.
Note if muting is experienced or not experienced.
Tune to SXM Channel 2.
Note if muting is experienced or not experienced.
• If both channels experience muting, the SXM
filter is most likely not an appropriate correction
for the condition. It is unlikely that the
customer’s concern is a result of the
interference described above. The technician
should follow SI diagnostics and repair as
necessary.
• If channel 1 is not muting and channel 2 is
muting, there is most likely interference from
transmitting sources outside of SXM’s
frequency range. The SXM filter is most likely
an appropriate correction for the condition.
Install the SXM filter inline between the coaxial
antenna connection at the back of the radio (or
radio tuner) and coaxial cable connector.
Note: If adding SXM filter, follow the Radio
Replacement in SI to get to the coaxial.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
