the 04 and up does from the cavs
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
dont waste your time get an aftermarket.....and those cobalt radios are not gonna fit....You can get a aftermarket that plays mp3's for 100 bucks....why spend 150+ dollars on a factory radio when you can get a decent pioneer for that price that will do everything for you (aux in put, 3 preouts, i pod connection, play any cd, and give you better sound)
im not actually using the unit to power my stero i want it to be totally stealth and i feel that a stock looking head unit will complete the look, it will be powered by a fosgate 3sixty.1
