I called my Garmin dealer and he didn't know anything about it. In
fact, he was putting in a 330 to read out on a 530.
I called Garmin and the man answering didn't know about it and would
"pass it up the line".
I called AOPA and they knew and said it was true. They are on it and
have no further info re how many or which ones. The will post info on
epilot.
I am writing AOPA, Garmin, and FAA. We have to stop this as it is one
of the best things for GA in a while. If you have seen and flown with
it, you will get it.
