I've reading in a UK forum that some of the first cars have this feature. Is it available here in North America( Canada in my case)?
There is an option in the user-selectable menus to set an upper speed limit. (If that's what you're referring to)
Here is the original thread: https://www.speakev.com/threads/intelligent-speed-limit-warning-missing.136352/ It is supposed to read the real maximum speed and show it with the speed from the gps
