I have a Kenwood KDC-MP528 CD/mp3 player. The motorized face gear broke so the face isnt motorized anymore, but it still works. You can move the face manually to eject CDs. It comes with the headunit, sleeve, wiring harness, remote, and I think I still have the manual with it.
My wife was rear ended a couple of weeks ago and the accident cause the radio trim to pop out of the dash. The deck hit the gear shift and broke the gear.
If your interested I can get pic of it and also power it up on my bench to prove it works. Ill trade it for the Nano. Let me know.
