Gm Factory cd players with aux input?
With your 02 you will be able to use the GM9-AUX for auxiliary input and still retain the factory CD changer if you have one. 01 and 02 models were capable of controlling more than one external device (99-00 models didn't have that feature). The GM9-AUX has a changer pass-thru port so you can leave the change connected and still add an auxiliary source like satellite radio or an MP3 player.
