I understand that.
I dug around on GMPD for like an hour and FINALLY found it.. 08 us8 code radio.. I ordered one.. I'll check it out when it arrives and put it in.. then have it re-married to the car. Not a problem by me..
I wanted an 08+ deck because it has a factory aux in connector on the faceplate and my 07 does not.
Good to know the decks are not different though. I checked my glovebox build info prior to order, I do have a us8 code 07 deck so the us8 08 deck with aux in should work after reprogramming.
For anyone curious of the answer to my question however, when I get the radio I will post the part # for future reference.
Maybe I'm insane
but I imagine some other picky "stock look" people such as myself may be interested in doing this kind of thing to their 05-07s if for whatever reason.. they can't get an aftermarket aux in to work, or really dont want to fool with aftermarket components at all.
and thanks for the info!
