The only mod I have done is the RF set up for XM radio. I do want to change out my head unit, because like you, I can't stand not having MP3 playback.
Disregard, found the site with manuals and the supplement for the 2008 g6Do these stereos come with a manual as well, or would that be part of the 2008 G6 owners manual?
That's my understanding. I believe the 2009 or 2009.5 have the mp3 capable stereos, but the 07s and 08s didn't but had the multi disc changers and / or XM capabilities and of course the aux input on the frontso the 2008 stereo will not play mp3 cds?
