My advice would be to just take the entire stock deck out and go get a cd player from pioneer or alpine or something like that.

ebay has a lot of them. they are pretty inexpensive and i would advise going with a new one. you can hook a 6 disc cd changer to that tape deck also. you can buy a factory one, but they are VERY expensive or you can get an alpine one for much less. all you need is the cable and the changer. but you can not hook both a cd player and changer to it. if you want to keep the stock look, this is the way to go. good luck
