Agreed. The only components with “availability limitations” are those Garmin chooses not to address. The only electronic components I’m familiar with that are in shorter supply or can’t be bought for less money than they were 25 years ago are vacuum tubes. Garmin started this kind of thing the minute they acquired UPSAT, the only difference between that time and now is that Garmin has graduated from shaking owners down for thousands of dollars and is now shaking owners down for tens of thousands of dollars.
