I'm having exactly the same problem.  Any solutions yet from Pioneer short of a new unit?  I customized my dash to accept the 7600 NEX so prefer to stay with that model head unit vs. switching to different brand. 

I'm curious if this issue was ever resolved.  I'm having exactly the same issues.  Attempted a "factory restore" that made a maddening situation worse.  Unit now sticks in a boot up loop.  Splash screen for about 5-7 seconds, then black screen for about 7 seconds, then splash screen, etc.  Will do that all day long until I pull main power fuse.
