I ended up buying 3 magazines before I finally got the correct one for my SHOwagon. (Thanks to eBay, I was actually able to re-sell them and make a few bucks.) I don't know for sure it will work with your player but it's worth a shot. The wrong ones I bought actually were the exact external dimensions but grooves on the bottom of the magazine were different.
Another idea is to ditch the CD player altogether and hook up one of those interface devices that allow you to run an Mp3 player through the factory stereo. That's what I did. Now I have access to thousands of songs without ever going to the back of the vehicle!
