Setup: Garmin GTN 625, SL-30 + Trig TT-22 with control head + GRT Horizon 10.1
Problem 1: I get a "VNAV Unavailable: Barometric Altitude Lost" error message on startup.
Curiosity 1: I also was not getting LAT/LON to the Trig for a while until I changed the output format from ADSB +1 BACK to just ADSB on the GTN 625 (feeding the Trig TT-22). Does anyone know why???
Soo ...
Does anyone know what settings work with the combination above?
[I **KNOW** that it works with the GTN 650 + Trig TT-30 + GRT HXr (Legacy)]
I have gone through Garmin/GRT/Trig documentation and for some reason, I must be missing something.
I have called Garmin and I have a call into GRT as well.
FADC 1? Fuel Air Data "Z" (what I have used in the past) format or "S" (which had barometric altitude) or maybe even "D"??
THANKS ... I have already scratched all of my hair off my head.
