If your 2003-12 GM has an XM Tuner module in remote area, this easy peasy auxiliary jack is for you!

Did you know many 2003-12 GM Truck, cars and Suv's were factory equipped with XM and even though trial period or subscription may have expired, the XM tuner module remains which is great news if wanting to add an aux input jack to your ride. The XM tuner module is a metal box installed in a remote location, not built-into the AM/FM radio. How to i know if vehicle has required XM Tuner module? Easy: Press "BAND" button until XM is displayed; if only AM, FM is displayed, vehicle does NOT have required XM tuner and will require an auxiliary input adapter instead. With the AUX-GM3x installed, users can connect and play portable audio devices (e.g. smartphone, iPod, MP3 player and more). To install simply connect male plug to XM Tuner Module (usually behind glove box, hatch or trunk area), route and install 1/8" (3.5 mm) jack on or near dashboard and connect audio device. When in the mood for XM (if subscribed), unplug audio cable from jack-- its that simple--- no complicated setup or wiring. If you prefer wireless , the same can be accomplished with our A2D-GM3x.
» Vehicle must have XM radio Tuner (DRR Module) with or without subscription.
» Connect and play iPods, iPhones, MP3 Players, Tablet, Smartphones and more
» Use Smartphone or Tablet to stream music apps, turn-by turn navigation and more

    This is an awesome harness and easy to install harness on my 2007 Trailblazer LT. It gives you an aux input while keeping the factory head unit and not losing Sirius XM radio. The music is very clear with no static or interface. It also works great when you receive a phone call. Caller can hear very clearly and all sound comes through speakers.
