haha okay - That makes a lot more sense. I'd still need to take it down to a GM dealership to have it unlocked or whatever, but I can deal with that as a last resort, though.
But, I'd really like to have a stereo with an AUX jack. I'm going to head to another car stereo/accessory place tomorrow and get a second opinion. I don't need it to look perfect right away. I can always buy the dashboard attachment thingy later.
