Last year I replaced the tape deck in my 1999 Durango with a pioneer
DEH-P47DH. Now I am looking for a 6+ Disc MP3 Changer that will be
compatible with the pioneer unit.

Originally I was looking at the SSI America NeoChanger MP3, but their
support team says that the do not have a connector for the DEH-P47DEH.

I do not want one that uses the FM Modulation to connect to the CD
Player, I would prefer somethign hard-wired.

Does anyone have an suggestions as to what Changer I should look for?

Another option is to replace the Pioneer with another in-dash CD/MP3
player that will accept multiple disks.
