Yes, I have the new firmware on it. I got it from the European Pioneer site. It said it was only for the F310bt, the European models. The txt file in the update folder said it was also for the U310bt, so i made the update. Though i must say i updated it not because i had some issues, but just because i had an opportunity. The device works after the update exactly as before, with just one difference: when using the detachable unit, it does not power off instantly when i switch it off but takes about 2-3 seconds to switch off. Once again, no issues either prior to update or after it.
