Post some pictures, they are really not that hard to remove but it would help to see what you have. I did mine in the '03 CCD in 30 minutes.
BTW - Lots of car stereo dealers will replace the stereo at no charge if you buy a model of a certain price range - Circuit City wants you to buy one of $100 or more. Had them do my wifes Toyota several weeks back - it was more for the dash replacement kt but your AS will not need that. The pigtail in the box will work - all AS does is use crimp connectors. My wires were labeled, you may need to do some looking in your owners manual first.
