retrofit cd changer in 04 DeVille

Hi there-
 
I have an 04 DeVille standard with a single CD player.  Could a install a Caddy 6 CD changer in the glovebox and use it without putting in a new stereo?  What wires would I need and would it be worth it for the ammount of work required?
 
THANKS, Brad

You need to follow instruction with deck. If looking to purchace make sure it is compatable with car. Do your homework prior to purchase.

Well, I was going to get a used one, thus no instructions.  I agree research is very important.  That's why I am asking you experts.

LOL. Responce it still correct, even with used get make and model no. contact mfr tech support if possible for intructions and compatibility. You could also post your choices and maybe someone may have experience with deck you're planning to use.
