I had big issues as well, but I note that the person who bought my Pelagic installed the software updates and apparently has been using the unit just fine for almost two years.
Whatever the case, while I grumped about my issues here on the forum a bit, I recognized that the way to solve them was to talk to the guy who designed them, and that going on about it here on the forum probably wasn't a good way to get help or get the pilots to work as designed.
