Would a map update help with FSD or free AP? I'm thinking speed limits, lane selection, and maybe even navigation route planning. It's my first map update. Thanks.
We get a full Navigation Data update about every 9 months and "invisible" small (probably local info) Delta updates all the time. The Navigation Data covers the entire North America (if that is your location) and covers changes made in North America in the last 9 months.
