it just stopped working. it blinked a few time here and there. so i went to have it fixed and they wanted like100$ to fix it but for that much i'll just get a new HU. then i started to poke around on the net and it seem that this is a common problem with this unit or any or the double faced fold out. well any way i down loaded a service book and i think i found out what part it is the ribbon cable (which is only 11.xx from pioneer) but im not sure .so if you have fixed this before can ya let me know if this is the problem please.or if you have heard anything about this that i my not know.
