My plane is in the avionics shop for some Garmin updates. Avionics guy says Garmin has firmware updates for the GTN750xi and the GTX345. Anyone know what these updates do? Are there any new features or are these just fixes?

If your GTX345 doesn't have 2.54 then I'd do it. Probably doesn't affect you but without that update it won't talk to a Flight Stream 210. Here are the notes on 2.54:
