You can set a max speed "WARNING" through idrive, as in, if you go faster than a certain speed, the car will warn you. That does not require driver assist, as I can set my max speed warning (and have it set at something like 90 and have never heard it).
What the OP is talking about is driver assist/ driver assist plus, which is being able to see the speed limit info in the HUD.
I have not seen anyone post about successfully retrofit a fully working version of either driver assist or assist plus. If it could be done, it would be pretty darn expensive as the car would also have to be re coded to accept the retrofitted parts. I suppose anything is possible if you throw enough money at it, but a good rule of thumb with BMWs seems to be to "order it up front if you think you might want it", because there is not much support through bmw for officially retrofitting much of anything.... even things which should be easy like bmw apps for example.
