ol' cd player thoughts

So I may be the only one left witht the original cd player, but hey, it worked, finally quit though.(typical symptoms posted around here) I searched around, just a new head unit and wiring harness to use the factory speakers, seems easy enough (I use that in a very loose sense). So. is there a special tool I'll need to get the factory decks out, I'm guessing those holes on the sides of the face have something to do with removal. Or is there a fix for the factory cd player, maybe some way to clean it, or is it dead? thanks for any help, Later
