Speed Limit Warning

I recently bought a 2021 GLC63 SUV, and it has a speed limit warning in the speedometer housing that flashes if you go above or below the limit. I tried to look this up in the owner's manual. but can't find anything. Is there any way to turn off this warning?

2020 GLC300 & 2009 SL550 (previously had 1999 CLK / 2006 E500 / 2011 GL450)
Go to SETTINGS in the MBUX system.
Under ASSISTANCE, look for the Traffic Sign Assist item, and click it

In that menu, if you select "OFF" in the Warrnings section, I think that will eliminate the annoying flashing. Unfortunately, you can't set the warning for any more than 5 MPH above the limit, which is kind of silly. I wish it could be set at 15 MPH over, since you'll get run off the road doing 5-over the speed limit on most highways!

If I remember correctly, you probably don't want to turn off the bottom "Show in Center Display" option, unless you don't want the speed limit showing on the Navigation screens (it doesn't flash there, it just displays as a small thumbnail"

I just took the time to try out your fix and it works as advertised. Thanks again.
