Today I called Garmin Support… twice… about the pitch oscillations. On the first call, the gent told me this was a known issue with Bonanzas and SW ver 3.10 was released in Jan 2022 to fix that. He said I could check my GFC SW version on the G3X: “Menu-Menu, LRU, look for Autopilot.” I went over to the plane and tried. Nope. And of course I had hung up by then.
Being a glutton for punishment, I called back, and got a different guy. “It’s a known issue. There’s a fix and your installer will know what to do.” He did not know what the fix was; he muttered something about “configuration.” Hmmm. I asked about accessing SW version, and he said that info was not pilot-accessible. Great.
There are too many reports to assign the issues to manufacture, airframe, friction, iPads on the yolk, etc. Like I said, my Century2000 was 45 yo tech and it held ALT perfectly. Bonanza drivers saw it, they complained and out comes a new SW version. MSers need to do the same thing. It is the GFC500!
