If you have a Pioneer 860MP headunit and your control/volume knob broke off. Use this Item# XXA7381. The knob cost $15 dollars plus s/h. I'm just making this thread for other users around the world who have the same problem. So I guess Pioneer does stock up on every little piece.
No problemo. I can already see that this thread has already made its way to google search. I tried searching for this before and found nothing! Now this is available to everyone around who searches.
