XM Tuner module
Introduction
Thousands of GM Cars, Trucks and SUVs are fitted with an XM Tuner module but
lack an input jack for Smartphone, iPod, MP3 player etc. but here is good news.
See, GM installed an XM tuner module in many vehicles and even though the free
introductory offer may have already expired, the XM tuner remains installed and
this is great news for anyone looking to add an AUX input. The AUX-GM3x cable
uses the XM port to provide a 3.5mm audio input for all kinds of audio devices
including Smartphones, MP3 Players, iPods etc. while also retaining XM playback
(if subscribed). Be mindful that your vehicle MUST have an XM Tuner module
(with or without subscription). XM Tuner module is a small electronic box (See
Fig. 2) installed in a remote area of vehicle.
Warning: XM tuner module is not part of, or built-into the AM/FM
radio. See table at the end of this guide for XM tuner location.
See Frequently Asked question at the end of this guide for more details.

Frequent ask questions & troubleshooting
1. Does the AUX-GM3x work in all GM Class-II vehicles?
YES; so long vehicle has an XM Tuner module with or without subscription.
2. Will I be able to use smartphone speakerphone feature?
Use smartphone speakerphone mode to hear callers voice on car speaker.
This feature is limited by smartphone not this cable.
3. My vehicle does not have an XM Tuner, how can I connect/play my
portable device?
At present we have no offering for vehicle without XM Tuner module
4. Which cable length should I select from options?
Measure distance between XM module and location where you intend to
place 1/8” audio jack and select from available options.
5. What’s the difference between Expired and Active and which to I select?
Expired subscription and NO intentions to renew, purchase “Expired”
Expired subscription and intent on renewing at future time, purchase
“Active”
Important: Expired version will not allow XM playback at any time,
therefore to retain XM playback (now or in the future), purchase “Active”
version.
6. I don’t know if vehicle has XM Tuner. How can I find out without ripping
car apart?
Turn radio “ON”, press “BAND” button repeatedly as radio cycles through
AM/FM/XM1/XM2. If only AM/FM is displayed, vehicle does not have
required XM tuner.
7. My factory radio has a “BAND” button but no XM tuner. Will this work?
NO; For the AUX-GM3x to work, vehicle must have an XM tuner module.
8. Do you offer a music streaming option for my GM with XM Tuner?
YES, See our A2D-GM3x
9. After connecting everything, playback is noisy/humming. Any ideas?
Ensure audio device volume is set to 80% or more. When listening to XM (if
subscribed) ensure audio jack is empty.
