I read the Mooney Acclaim Ultra flight trial article in the October 2018 Aviation Consumer with interest, and have a couple of comments tangentially related to the airplane.

I have never explicitly seen it written anywhere that when one buys a glass panel airplane like the Garmin G1000-equipped Mooney Acclaim, the aircraft OEM owns the software for the avionics. This has been a problem with Mooney through its various bankruptcies and production hiatus. I don't know if it has been a problem with other OEMs, and I understand only Mooney Service Centers (which seem to be few and far between) can do the G1000 software upgrades.
