General Stereo Question: MP3 CD Changer?

Ok this question isnt SVX specific I suppose, but since its for the stereo in my SVX, this is the appropriate place ....

I bought a JVC El Kameleon head unit last year for my SVX, as I was mesmerized by the cool graphics, and the nice fade-to-black face is pretty cool to show off. I'm not the adventurous type, so I had Best Buy install it, (which is a LONG story of its own), but they told me it was VERY hard to install a head unit in the SVX, blah blah, we need to take off the dash, blah blah, hardwire... OK so $100 in install fees and 3 months later I have a nice new head unit (same long story).

This was a few months before MP3 compatible head units became cheaper. I REALLY want MP3 capability, and I dont have the money/hassle to replace my unit, and its really nice anyway...and my unit is JVC changer compatible...so getting to the final question...

Is there such a product as a MP3 Capable cd CHANGER???? That can decode mp3s and play them through my non mp3 compatible head unit. Maybe I need JVC because of "J-Link"? Can anyone help me out? Thanks guys!
