Most (but not all) who have upgraded to v2.120 report similarly favorable results. So there now appear to be fully two independent solutions to vanishing radio and nav settings.
Well, as they used to say in the South, "Hush my mouf'!" Today, after almost exactly three weeks, I got in, punched the driver 1/2 setting button as usual, and -- poof! -- presets gone.
So the EVIC approach with earlier firmware (ours v2.110) obviously helps a lot, but isn't bulletproof. From comments in JG, it appears something similar may apply to v2.120.
Maybe doing both tweaks will do the trick...
