Have you found a resolution to this? Same thing happened to me out of nowhere yesterday. Stable install since this past summer, then boom, calibration is way off. And the whole "if you're having issues tapping your screen or with responsiveness to screen taps, tap the ok button below to continue with calibration" WTF?
So frustrated as to why isn't screen calibration the first thing that this device wants to do after a hard reset like EVERY OTHER WINCE DEVICE! so frustrated.
I've disconnected the HU and am hoping it's internal battery drains and it forces a reset in the morning, if n
