From your description sounds more like the speed limit warning and not the speed detection. Speed detection is more of a square with the speed inside.
As noted above, Speed limit warning is a user set feature:
idrive - settings, speed, warning at, and enter what you wish or turn off.
If you have the speed limit detection feature it will be listed here:
idrive - settings, info display, speed limit information
And btw there is a top speed limiter. I think its 150mph but could vary based on model and packages. Go to bmwusa and look up your model to be sure.
