CD player CD Changer question

Guys , i'm posting this message on here hoping on of you have experienced a similar situation .
I just bought this Lincoln Mark VIII 1998 and on the CD display i can see the CD buttom but not CD slot and no CD changer anhywhere in the car not in the trunk and not under the seat .
When i press the CD button it says NO DJ , i looked this message up and basicly what it said is that no CD changer connected .

can i just buy the CD changer and hook it up ?
is there alot of wireing need to be done ?>
is it a remote control CD changer ?

any inputs is appreciated

I have exactly the same situation. I too just bought a '98 Mk VIII with no remote CD changer although it has the installed JBL radio for one, and would apprecite an advice as to installing the changer.

one of two things have happened.

either the original radio was replaced with another one somewhere along the lines, and the car never came with a CD changer

or

the trunk mounted CD changer has been removed. If the car came with a CD changer, you need to check the driver's side rear corner of the trunk. Lift up the carpet and look for the harness.

The ON/OFF buttons on these radios are a commonly failing part(they wont turn off the radio when depressed) so many past owners replaced them since all 1995-1998 stereos are a direct plug and play. However, if your car never came with a CD changer in the trunk, then the CD option on your head unit is useless.
