Have a 12 disk Delco CD changer from my old car. I want to sell it. How do I know what cars it can go with?

I have a 12 disk Delco CD changer I took out of my 1996 Saturn SL2. I want to sell it on ebay but I'd like to know what other cars the unit is compatible with first. I went to Delco and Delphi sites to look up by the part number but that didn't work. I want to dump this thing before everyone has an mp3 player in their car and cd changers are obsolete.
