XM TUNER MODULE (U2K) WITH OR WITHOUT SUBSCRIPTION
Introduction
Many 2003-12 GM Class II vehicles were factory equipped with an XM tuner
module and 1-year free subscription. Many renewed their subscription while
others let it expire turning the XM tuner into an ornament. Thanks to the A2D-
GM3x Bluetooth module, the XM tuner can be used to provide a wireless music
streaming solution for smartphone, tablet and works whether subscription is
active or expired. A Bluetooth connection means no wires, clutter or complicated
setup. Simply connect the A2D-GM3x to XM tuner module in remote area of
vehicle (trunk, hatch, below glovebox etc.) pair audio device, and enjoy. For the
A2D-GM3x to work, vehicle must have XM tuner module (with or without
subscription). If subscribed, service remains uninterrupted (no longer will users
have to forfeit XM). Simply select subscribed or not subscribed from options on
product page.
See Frequently Asked question at the end of this guide for details.

Frequent ask questions and troubleshooting
1. My vehicle has a 6-CD changer radio (changer built-into radio), will
this work?
Irrespective of AM/FM radio; vehicle must have an XM Tuner module
for the A2D-GM3x to work. XM tuner is a metal box in remote location and
is not built-into the AM/FM radio.
2. My XM subscription has expired, will the A2D-GM3x work?
YES;so long vehicle has an XM Tuner module. See Question 4.
3. I’m not the original owner and don’t know if vehicle has XM Tuner
module. How can I find out without ripping the car apart?
Turn radio “ON”, press “BAND” or “XM” button repeatedly to cycle through
AM/FM/XM. If only AM/FM is displayed, vehicle does not have the
required XM Tuner module. See Question 5.
4. My XM subscription is currently expired, but plan to renew at a later
date. Which version of the adapter should I purchase?
Select “Subscribed”, otherwise XM will not play upon activation.
5. My radio has a “BAND” button but vehicle does not have an XM tuner;
will the A2D-GM3x work?
NO; Vehicle must have XM tuner module for A2D-GM3x to work.
Purchase our BLU-GM3 instead.
6. Can I place hands free calls?
NO; the A2D-GM3x does NOT support Hands-Fee calls.
7. Why do I have to locate a +12V accessory wire?
There is no 12V accessory supply at the XM Tuner, therefore one is required
for the A2D-GM3x to work as described.
8. What’s the difference between “Subscribed” and “Not Subscribed”?
Not subscribed means you no longer have a service plan and do not intend
to activate in the future. Subscribed means you have an account or plans to
activating at a future date.
9. What is the difference between the A2D-GM3x and A2D-GM3?
The A2D-GM3 connects to the radio and the A2D-GM3x connect to the XM
