Play portable audio devices in any 2003-07 CTS and SRX with XM Tuner module.

Does your 2003-07 Cadillac CTS or SRX include XM radio (U2K package) but no connection for Smartphone, iPod, MP3 Player or Tablet? The AUX-CTS cable affords these vehicle owners the opportunity to connect and play portable audio devices without compromising XM subscription or wiring integrity. Simply remove radio, connect cable, route and install 1/8" jack on or near dashboard, connect audio device to jack and enjoy the best possible sound on car speakers. When in the mood for XM radio (if subscribed), unplug 3.5mm cable from jack. -- its that simple --- no complicated setup, wire cutting or splicing. Remember the AUX-CTS only works in vehicles with XM Tuner Module (with or without subscription).

    If you have a older Cadillac CTS that don't have a aux jack , this is the product for you. The installation was very easy, the harness fit right in with no problem. Its worth the money to buy this harness if you want to kept all of your factory radio settings and all the things it can do without buying a new radio. I am very pleased with the purchase

    I received this product and installed it in no time, and as soon as I installed I tested it and noticed something strange. The sound on the driver side was great quality, but on the passenger side it was not good at all. I removed my radio prior to ordering to make sure that I ordered the correct one for my vehicle. Hoping to get this issue resolved and have a product like I was hoping for.

    Hello: This is due to a slight wiring change made by GM in the 2005 production. The change affects CTS models between 2004-05 making it possible for early production year 2005 to have 2004 (old) wiring and late 2004 production to have 2005 (new) wiring. If you own a late 2004 or early 2005 production CTS, click installation instructions for details. Any customer in this situation are able to return cable for a quick fix or contact us for a DIY.
