Need some help -- cd changer

I have the 95-00 delco unit with the 7 band equilizer on it, but the cd player quit working, I want to put in a cd changer rather tahn get a new head unit. Are there any units out there that will work with the existing controls on my unit? if not, what have you guys done as far as adding on a cd changer?
I'd like to get a 6 disk so that i could possible mount it in my glove box?
any ideas? thanks for you help
