Just a warning about how to update. USE A BLANK MEMORY STICK. I used one I had used from a prior year and got some rather odd results (due to a mix of old and new files). Did the update again with a blank stick and all was well. Lesson learned.

No need for new stick. Just delete the old updater files.

Hank,

When I opened the updater zip file it contained several folders and an unknown number of files.

I dragged this group of new folders+files on my old non-blank pre-used memory stick assuming (!) that this would overwrite the correct collection of old "stuff". Based on my outcome this was a bad assumption on my part. I have to confess that I wouldn't have known which were the "updater files" and which I would need to delete.

PS - The CNII updater installation instructions clearly states, "Copy and paste the contents to a BLANK USB STICK." (emphasis added). Not that I typically read instructions because, gall-darn-it, I *KNOW* how to update glider avionics! Yet another bad assumption on my part ... ding-blast-it.

YMMV, John OHM Ω
