    AUX-GM3
This cable installs to the 12-pin socket at the rear of AM/FM radio in 2003-12 GM with remote CD changer, RSE (DVD) or hideaway XM module (U2K).

GM owners looking for ways to connect and play portable audio devices on car system will be pleased to find our AUX-GM3 AUX input jack cable. For this cable to work, your 2003-12 GM must have at least one external player (not built-into radio) such as XM module (U2K), remote changer* or RSE (DVD). (DVD, changer nor XM module are not built-into the AM/FM radio but installed in remote location). To install, simply remove AM/FM radio from dash, connect 12-pin plug to radio's 12-pin 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 a fully functioning factory option.
» Works in vehicles with Remote changer* or XM module (Subscribed or not subscribed) or RSE (DVD).
» Play audio devices including iPods, iPhones, Smartphones MP3 players and more
» Connect smart device and stream music from popular sites like Spotify, Pandora etc.
» Connect smart device and listen to GPS, satellite radio, audio box, apple music apps and more on car speakers
» Retain original look and feel of dashboard components and wiring integrity
» Plug-n-play to 12-pin socket on AM/FM/CD or Tape radio (radio removal required). If you prefer an aux cable that connects at the hideaway XM module; purchase our AUX-GM3X instead.
[To avoid costly returns, It is important to observe all requirements, warnings and install guide information prior to purchase.]

Paying for a faster delivery method (e.g. Express mail, Priority mail etc.) for products requiring "assembly" does not speed up assembly (build) time; however, it does speed up delivery time.
Delivery time for in stock products requiring assembly= Assembly time (2-4 working days) + transit time (your shipping method).

    First off I want to say thank you so much, I was about to install the device in my truck this morning in about 30 minutes. The thing that took the longest was getting the little washer on the end of the six cord after I drilled it, super easy setup. Also thank you for knowing the unit well enough to tell me I didn't have the wrong part just needed to install it in a different area. You guys replayed really quick and replied while I was on the night shift (never seen that before!). Thank you again and I will be a customer again.

    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
