Hi,its my first post on this site and it looks like i've found an awesome site.I have bought a second hand head unit Domain DM-DV5662NVU and when it first powers on a nice picture comes up then it goes straight to the calibration screen.I followed the instructions in which you hold the stylus for two seconds and follow it around the screen doing the same two second press on each stop,it then says if you would like to save these changes tap the screen.I tap the screen then this message appears "application error CE4E01.exe encountered a serious error and must shut down" and there is where it stays and is very very frustrating,any help is hugely appreciated..Evan.
