Adding an AUX jack to a stock radio.

    Has anyone tried installing a 3.5mm audio input jack to use with your iPhone/iPod? I had one in an aftermarket radio on my first Z71, but I've since sold that truck and now I'm back with just a stock radio with a single CD player. I've seen a write up that someone on gmfullsize.com did, just wondering if anyone can clear up exactly which connections I need to tap into. I probably just need to crack into my unit and look around, but I'd like to have a good idea of what I'm doing before I screw something up. Here's the other thread just for reference... http://www.gmfullsize.com/forum/showthread.php?p=3315388

    Does it have a Aux button or CD Changer ? XM Button? Can you post a pic of the radio?

    I just completed this. I tied it into the XM wires on the black plug in back of radio. I don't have an XM subscription but it only disables it when then3.5mm plug is in the jack. Soldering the wires to the jack was a PITA but I just took my time. All other radio functions work normal. I soldered and used heat shrink tubing on the connections to the plug in back.

    If you look at the OP,the link to another forum, post #8 BY CHEVY MAN and scroll through his pics you can see the way he connected to the plug on the back of radio with details. That's what i followed but i mounted my jack in a different place. i will post a pic later showing that. The whole panel where I mounted the jack pops out. You just have to unplug the power port wires and you can take it with you to work on it.
