cd changer?

Hey guys, My girlfriend drives a 98 sable and she wants a cd changer in it. Have any of you hooked one up to the stock radio? There isnt a cd player in it now but there is a button that says disc 1-6. I checked her trunk and theres no cd changer in it. So im kinda assuming that its set up for one to hook right up to the stock sterio. but just doesnt have one..If any of you have put a cd changer in your 98 sable i would really appreciate some feed back.. thanks alot.

Okay, the 98 sable has a front radio and a back radio unit. The back radio unit is located in the trunk, drivers side, mounted on the rear wheelwell. The factory cd changer connects to the rear unit by a small harness. The changer mounts in the trunk and is controlled by the front radio.

i hope this helps you in some kind of way.
