My car is on 250gps fiber wifi
Mark Zuckerberg? Is that you??
Anyway, I had my car at the SC last week, and they updated me to 14 and just Tuesday I updated to 14.2. No new maps as of yet, but the loaner I had DID have the new maps and it was on 2018.6, or something similar, if I recall correctly. Definitely a firmware before 10.4. But it had the new MCU, so that could also be a consideration.
