Good luck with this as almost all of them develop an issue with the volume control knob.
I am wanting to buy the double din Pioneer unit that came in the M-editions. Looking for one in mint condition in good working order. Let me know what you have!
EDIT: MPSS radio

Yep... I have one out of a 96M that looks great, but has the volume control issue. I am sure that it must be possible to take it apart and replace the pot, but I have not heard of anyone doing it.
