This cable connects to the AM/FM radio in 2003-12 GM with remote CD changer, RSE (DVD) or XM module (U2K) to provide an AUX input solution.

GM owners looking for ways to connect and play portable audio devices on the car system will be pleased to find our AUX-GM3 aux input cable. For the AUX-GM3 to work, your vehicle must be equipped with either an XM module (U2K), remote CD changer* or RSE (DVD). (Vehicle must have at least 1 of 3 factory options). To install this cable simply remove the AM/FM radio from dash, connect 12-pin plug to 12-pin radio socket, route and secure 1/8" (headphone) jack on or near the dashboard. When in the mood for tunes in remote changer or XM (if subscribed) or RSE, simply unplug audio cable from jack-- its that simple--- no complicated setup or wiring. With the AUX-GM3, GM owners are able to connect and play portable audio devices on the car stereo system while retaining fully functioning remote CD changer, XM subscription or RSE (DVD).
» Works in vehicles with Remote CD changer* or XM module (Subscribed or not subscribed) or RSE (DVD).
» Play many audio devices including iPods, iPhones, Smartphones MP3 players and more
» Stream music from popular sites like Spotify, Pandora etc.
» Use Smartphone to listen to apps (e.g. navigation etc.) on car speakers
» Retain original look and feel of dashboard components and wiring integrity
» This cable connects to 12-pin socket behind dash mounted AM/FM radio (radio removal required). As an alternate, purchase our AUX-GM3x which connects to 16-pin socket on XM module (U2K).

    Discount Car Stereo not only provided exactly what I needed for my vehicle, the level of customer service was beyond expectations. I reached out via email, concerned that I had purchased the wrong part by mistake. Within a couple of minutes I had gotten an email response back assuring me that I had made the right purchase. Not only did I get an instant response, the email included a link to the directions I needed for the installation. Professional, quick, and thorough. I don’t know what else you could ask for
