Rob,
Sorry, I did not intend that post to sound like I was attacking AFS. I think you have good products but I thought the comparison sheet was very marketing based, thus my suggestion for each prospective customer to create their own comparison.

I know a person that stalled a Mooney on approach and crashed it. After walking away he realized what that warning horn was?. He will tell you that if it had said ?Angle Angle Push? he would have had a different outcome. The less things that your brain has to process in an emergency the better. We used to also have the beeping and I too, thought it was great, until I started flying with voice alerts.
I've never even flown in a Mooney but if it is like the other planes I've flown, the buzzer means one of two things, you are about to stall or the gear is up and the power is way back.
I agree, "Angle, Angle, Push" would be nice but having flown a lot of airplanes w/o any type of electrical system, I have to ask, is it necessary? That was the point I was trying to get across. In the pattern, a buzzer of any kind will have me do one of two things, possibly both, lower the nose and add power. Even more so when a buzzer goes off and I?m watching the AS and see it down near the stall. I do hope the Mooney driver was watching his AS at some point during his approach.

The Dynon D-10A in my RV-4 takes over 24 minutes to backup and load new software (I have timed it multiple times), maybe it is broke? How long does yours take? The AFS unit will also backup all data to the SD card and it takes less than 3 minutes to load new software.
Please accurately time your unit and I will update the comparison.
You should see how fast it loads a map from the SD Card
I do not have a D-10A in my panel, thus I can't test it. I suspect you are correct on the time it takes to upgrade that unit.
However, the D100 w/ its faster processor takes just a few minutes to back up the software and perform the upgrade. I will not state a number as I didn't time my last upgrade but I'm sure it was much less than 24 minutes.
The AFS unit is nice, as is the Grand Rapids, and some of the others. The truth is, I would be equally happy with any of them and with all the changes and upgrades the manufactures are coming out with, it is hard to keep up.
The trick is to figure out which product best matches your mission, budget, and desires. Thus my initial recommendation.
