I agree about the S80- Nice unit! I've been using it with the stick controller, and I highly recommend it over the panel buttons and knobs. Setup is also key, as there are more features than I need. I have complained about the manual to LXNAV, and apparently, they finally did something about it. Just downloaded Version 6.01 (October 2017), but haven't looked at it yet. The previous version (5.46) was unchanged from the time I bought the S80 until this latest edition, even though the software went through several upgrades. I guess documentation in the software industry hasn't changed much over the years since I got out of it. It still lags way behind the product and is written by people who developed the software. They know it intimately, but can't communicate it to users very well.
