Sorry to hear about the problems with 781 compound release. I was going to book in to get the upgrade from 780 (we got upgraded previously in December), to gain some of the new features in 781 I played with at Sima, but think I'll hold out as it's running an AGI4 based receiver.
Looking at you screenshots of TRU the receiver is using GLONASS for positioning as they are on the left if that were not being used they would be on the right I am regarding second screenshot
