Connect and play portable audio devices in 1st generation CTS and SRX with XM module (U2K) code.

If your 2003-07 Cadillac CTS and 2004-06 SRX include XM module (U2K package) but no connection for smartphone, iPod, MP3 player, Tablet etc., the AUX-CTS is for you! The AUX-CTS cable affords these vehicle owners the opportunity to connect and play portable audio devices without compromising XM subscription or wiring integrity. To determine if vehicle has required XM module; press the radio "BAND" button to switch between FM1, FM2, AM, XM1 and XM2; if XM1/2 appears your vehicle will support our AUX-CTS, but if only FM, AM bands are displayed; this cable, sadly will not work. To install simply remove radio, connect cable, route and secure 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 (if subscribed), unplug audio cable from jack. -- its that simple --- no complicated setup, wire cutting or splicing. For the AUX-CTS to work, vehicle must have an XM module which is a metal box under rear deck (CTS) or rear side panel (SRX).
» Works in vehicles with XM module (U2K) with or without subscription
» Connect and play Smartphone, iPod, iPhone, Tablet, MP3 player and more
» Internet connected smart devices are able to stream Spotify, Pandora, Apple music, SiriusXM and more.
» Listen to apps (e.g. navigation etc.) on car speakers
» Retain original look and feel of dashboard and wiring integrity (no cutting or splicing)
» Connects at the back of the AM/FM radio.
» Plug-n-play without splicing factory wiring.

    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.

    I ordered an auxiliary adapter kit for my 2007 Cadillac CTS. I put it in this weekend over the course of 45 minutes. Thank you for the quality product and downloadable instructions. I will certainly keep you guys in mind for future projects.
