I don't have one for sale but I'll keep my eyes open. I know this unit is the same as the one in other Chevy's...not sure about the specifics though...anyone know of proper replacements from other vehicles?..wiring etc?
OK...I found one on eBay out of an '00 Coupe for ya. Dunno if you wanna go that route but here it is:
I located one from a company that was recommended by Bose. It's out of a Chevy truck. Same as the Corvette. I needed to add an accessory hot lead to number 9 pin in back of the factory harness clip or connectors. Sent me the cd am/fm radio and two extra wire pin clips. I'm now in business. Sounds great.
