I have a 2018 MX.
I later purchased the FSD and was told that no other hardware upgrades were necessary.
I also purchased a 2020 M3, without FSD, for my son.
The MX shows nothing new on the screen, i.e no traffic lights, no speed signs etc
The M3, with no FSD, shows everything!!
What is the problem here? Shouldn't FSD cars have at least the vusualization that non-FSD cars have?
