I decided to do a search to see if there were updates for my Garmin GNC 355 as I usually hear about it somewhere. It looks like in true Garmin form an update came out, was pulled, and now 3.21 is out with an April 2023 release date. I can't find the service bulletin which describes the release. For a moment I was praising Garmin about keeping the G3X manual up to date and now here we are showing poor form in not being able to find the technical document that describes a firmware update. So I'll give it a try, soon...FYI to anyone else with a GNC 355.
