I have a dual G3X Touch with dual ADAHRS about 18mo since install. I just started get this message (at all times, on ground, in air, etc). There isn't a lot in the Garmin manuals that I have found other than it seems to be missing an input.
If I got all 3 comparator warnings then I would think a bus was bad. But just Alt No Comp seems to indicate that Altitude is not making it across the bus and airspeed . attitude are okay. Just pulling a breaker gets me all 3 no compares and a fail.
I don't know how to debug this. Anyone seen this before or have an idea how to troubleshoot?
Thanks,
