Matrixion

ive been reading around, im gonna give this a try as it seems to be on the money: http://www.avic411.com/forum/viewtopic.php?f=33&t=25465

+1 on this one, i have reason to believe my backup is shot.

im gonna put it down to either of the two things i was doing at the time: I loaded a corrupt backup as av.exe just crashes, or more likely, im using the wrong windows CE images. might try find some other images and give thema whirl. ive go tthe unit connected to a breadboard and power supply, so i dont have to race out to the car to try things.

Having the same issue as you mate, ive resolved to removing the unit from my car until i can fix it, ive tried restoring my 2.00900 backup, but still get stuck on pioneer boot logo, press menu brings up an utterly useless menu, ive tried all sorts of things so far but nothing, ill keep you posted if i find anything that works.
