A real-world account of a G3X Touch to AXIS conversion: the configuration you rebuild by hand, the GMA 245R wire nobody mentions, a FADEC device that isn’t a checkbox, a database sync error Garmin support couldn’t crack, and…

Oshkosh dorm bookings open early and go fast, and if you wait until you’re sure you’re going, you’re not going. So…

A failure mode analysis of dual GSU 25 vs. GSU 25 + G5 in the Garmin G3X ecosystem — including what happens to the autopilot, and what the brand-new AXIS launch tells us about how Garmin itself architects redundancy.
