Considering that FDR's are designed to survive crashes and frequently don't,
I would be really surprised if any usable data could be extracted from the
avidyne after a flaming crash like this one. Doesn't matter what data it
records, there just isn't going to be any left. At least that would be my
guess.

If they can find the memory chips in the wreckage, they can download the
data. The chips themselves will survive fairly high temperatures and
incredibly high G forces. The G forces in an aviation wreck would be
unlikely to even damage the circuit boards. I don't know what kind of
memory the Avidyne system uses, flash memory will hold its data, but
battery backed static ram will probably not. Newer electronics are more
likely to use flash, but as you probably know, aviation gear is usually
five to ten years behind industry trends.
