An update. I needed to update through two revisions of the firmware. Now everything ticks over like a Swiss watch.

I'll write up mini review when I get the S80 into the cockpit. Bench testing, I couldn't be more pleased with what I'm seeing. Very easy to manage different modes of data display and presentation. Not that I have a wide range of experience to make comparisons - my only other electric was a Cambridge. But I like what I'm seeing.
