    AUX-GM3x
Any 2003-12 GM vehicle with XM module U2K) in remote area, can benefit from this easy-peasy auxiliary input jack!

Many 2003-12 GM truck, cars and SUV's were fitted with RPO U2K (XM package) and free 3 month trial which means your vehicle may still have the XM module which is great news if looking to connect and play an audio device. To verify vehicle has required XM module; Press "BAND" button on AM/FM radio to switch between FM1, FM2, AM, XM1 and XM2; if XM1/2 appears your vehicle supports our AUX-GM3x, but If only FM and AM bands are displayed; this module, sadly will not work.
Once installed; users may connect and play portable audio devices (e.g. Smartphone, iPod, MP3 player and others). To install; connect male 15-pin plug to XM module (usually behind glove box, hatch or trunk area), route and secure jack on or near dashboard (4mm or 5/32" shaft) and plug-in audio device. When in the mood for XM (if subscribed), unplug audio cable from jack-- its that simple--- no complicated setup or wiring. If a wireless Bluetooth connection is proffered; purchase our A2D-GM3x instead.
» Vehicle must have XM module with or without subscription.
» Connect and play iPods, iPhones, MP3 players, Tablet, Smartphones and more
» Smart devices are able to stream from popular music sites, turn-by turn navigation and more
» Retain original look and feel of dashboard components.

    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.
