Do any of those displays have the software at DO-178B Level C or higher?
(btw - I do know a little about the avidyne display)

I am very apprehensive about Avidyne avionics. What can you say about
their products?

I don't have any in my 140, but then, I don't even have any GPS whatsoever.
This is more a reflection of not needing to upgrade a good 1995 panel than
a reflection on Avidyne.

I can say that Avidyne was the first company to get a windows-based product
certified to a 178B level that would ordinarily be level C. Note that the
windows portion of the software does NOT comply with Level C objectives.
But last I knew, Avidyne consider the technique(s) used to be proprietary.
(I don't what they are, but I have some educated guesses on possible methods).

I've seen some demos of their products, which look way cool, but they are
also way too expensive for me.

Not much help - I know...
