" speed limit exceeded warning "

[X5-M power]

I got this message when I reach 120 k/m and above, so I contact my dealer if they can remove this warning or adjust it to 160 km, but they told me they can not do it !! the manual speed limiter is adjusted.... but this one is a standard and cannot be removed.
The reasone that I want to remove or adjust this warning, because Im driving a lot on the highways and the speed limit here is 140km - 160km when i got this speed message it won't go off till I reduce my speed under 120/km.

btw: I got red circle on center of the dashboard information says (LIMIT) and I can't use BC button

ANY HELP PLEASE ....
