Jeep Cherokee Forum - speed alert

Hello you guys
In my 2013 Grand Shiroki vehicle, there is a uconnect Rb2 system.
In recent days the system has suddenly started warning loudly, "You are over the speed limit".
I went through all the settings and did not find where to turn off this option, I must note that I do not have any option for a navigation system on any screen.
I even downloaded a software update on your site, and updated the software in the car, it also did not help.
Please help in finding a solution to the problem, it is very annoying.
Thanks in advance
