It would seem there was a hub update to 125.0 and the first thing I noticed was the g600txi was removed from the menu. My guess is they are going back under the hood to correct some of the bugs? I know I was unable to get the charts to work correctly. It seemed like they were getting closer to having a stable G600Txi option but I think it was the smart thing to do to pull it back for now. The other options on their Tnxi G1000 panel work flawlessly, gauges, G1000, TDS GTN750 etc.
