Intermittent OAT
I had a GSU25 issue where the OAT was intermittent. It would show up some days and other days it would have a big red X through it. Seemed highly unlikely to be a problem with the system so I checked my wiring numerous times. I measured the proper resistance values across the pins every time. I consulted with Garmin and although they were also skeptical at first (I don't blame them, I'm sure 95% of the time it IS a builder / wiring issue) they eventually sent me a replacement through Steinair and the issue went away. OAT comes up every time I switch on the system now! I was very happy with Team X help to troubleshoot the issue and the resolution of sending out a new GSU25 which solved the problem.
