Introduction
Thousands of GM Cars, Trucks and SUV’s have either a remote/external CD
changer, XM tuner module OR RSE but lack aux input jacks for Smartphone, iPod,
MP3 player etc. Auxiliary input adapters are available, but most require
disconnecting XM, remote CD changer*, DVD or all three; however, the AUX-GM3
auxiliary input jack, requires and retains these factory options to provides a
3.5mm input jack which can be used to connect and play all kinds of audio
devices including Smartphones, MP3 Players, iPods etc. Keep in mind for the
AUX-GM3 to work, the vehicle MUST have XM Tuner module or
Remote/External CD changer or DVD Player.
Warning: The AM/FM/6-Disc changer radio (changer built-into radio) is not
considered separate cd changer.
See Frequently Asked question at the end of this guide for additional details.

Frequent ask questions & troubleshooting
1. Does the AUX-GM3 work in vehicles with a 6-CD changer radio (the
changer is built-into radio)
YES; BUT an External (remote) device (e.g., CD changer or XM tuner)
required otherwise the AUX-GM3 will not work.
2. My GM radio has the option for a remote changer (CD/AUX button).
Does it have to be installed in vehicle before buying this cable?
YES; a working external CD changer or XM tuner must be installed in order
to use this product
3. My GM radio is XM ready (Band button); will the AUX-GM3 work?
NO;XM ready means the XM tuner module is not yet installed. Your vehicle
MUST have an XM Tuner module, remote CD changer or RSE for the AUX-
GM3 to work.
4. What is an XM Tuner module? Is that built-into the AM/FM radio?
NO; XM module is not built-into the AM/FM radio, but a metal box installed in
a remote area of the vehicle and is required for the AUX-GM3 to work.
5. Will I be able to use Speakerphone option on my smartphone?
Yes! When in a call enter speakerphone mode on smartphone at which point
you will hear the caller’s voice on car speakers.
6. My XM subscription has expired, will the AUX-GM3 still work?
YES; The AUX-GM3 will work because vehicle has required XM tuner Module.
7. I’m not the original owner and don’t know if vehicle has XM Tuner. How
can I find out without ripping the car apart?
Turn radio “ON”, press the “BAND” button repeatedly as the radio cycle
through AM/FM/XM1/XM2. If only AM/FM is displayed, your vehicle does not
have an XM tuner module.
8. I have all three (remote changer, XM and DVD) options; do I need to
disconnect anything for the AUX-GM3 to work
NO; the AUX-GM3 requires at least one factory option. The option could be
XM Tuner, DVD, remote CD changer or all three.
To retain use of RSE, XM or separate CD changer you must purchase
the “ACTIVE” version of this cable.
9. What is the difference between the AUX-GM3 and AUX-GM3X?
The only difference is where they connect to vehicle. The AUX-GM3 connects
to the radio in the dash, and the AUX-GM3X connects to the XM Tuner
module in remote area of the vehicle. (See plugs below)
** External or remote CD changers are installed in lower dash, center armrest, hatch, trunk etc.
