Ok if I understood correctly the infotainment system freezes up and practically your locked out of everything.
So what I do while driving, there is touch power button on infotainment.
You basically hold it or I say keep it pressed for a good few seconds, screen will flicker or go blank but keep it pressed, then I think at some point you would see beats logo, during that you will see all sort of messages errors this is not working that is not working etc. But it comes back .
Maybe next time try that.
I have not encountered it from a long time now.
Few days back I got the last update of software which people have been discussing here don't remember the version.
So not sure how that would behave.
But all in all you can come around by holding that button potentially a reboot of infotainment I guess.
Thats all while you are driving.
Cheers.
