Hi
I think/know you have the 6 disc cd changer that has DVD capability if you also had the video system. Here is a link to Mopar.com that describes the unit I think you have and talks about its capabilities if you were to add additional components:

Hope that helps. If you are interested in adding the video system, you can buy it from Chrysler and there are dealers who sell via the internet at a sizable discount. There also is Ebay which often has accessory items listed.
