Hadn't gone back through this entire thread to check (and I can't get in to iCloud for the master list), but in case anyone wanted to allow the Nav-in-motion feature, I had luck with that using the code from pre-'19. It's in the APIM section with all the as-built data, under 7D0-02-01. The first four digits need to be x7xx (changing the second digit to 7), or I had noticed in some threads on the web that those first four should be 5753. Worked with mine, and after a quick spin, I found I could play with the nav. Honestly, I hadn't even used it yet, so if the lockout wasn't even there with the '20, I'm happy I can still plug in an address without having to pull over.
