Thanks! I looked it up and it said not compatible with my 2014 Ltz. I called my local shop and they all said it's a different harness for the 13-14's and the dash and wiring out the door would be $375,I had the same issue with my old PAC. I would recommend using the iDatalink Maestro Module. Its easier to flash and you can retain 90+% of your factory options if you want.
I would rather do it myself, as far as the PAC's go, the OS-3 that was in my Yukon had those little glitches, but the one for my new truck they want to install is the RP5-Gm32. I can get that at crutchfield with the dash kit for $133.
