All the CD and Cassette players have the connection on the back for it, but most of the CD players do not have the ability to control the CD Changer.
If you look at the Cassette player here:
You will see the Tape/Play button at the top. When the CD Changer is connected, that'* how you switch between the two. Technically, it should say Tape/CD.
On the CD Players, I believe it has the ability to control a remove cassette, as some of the minivan'* had that option.
*As an FYI, I have both the 2 and 7 band CD and Cassette players, and a 12 disc CD and a single disc CD remote unit, and have tested various combinations and manufacture year (94 through 99) and have researched it online as i've wanted the 12 disc changer with the single CD up front for a while.
Edit: This is one of the ones that should* work with the CD Changer.
I say should because from what I read, the 99+ Monsoon ones had the option, but I will not guarentee it as I have not tried one myself.
