Located in UK so temperatures not yet at freezing. Car built Early 2016. No Android auto or carplay connection, just via bluetooth.
It's literally only the touch function, the display isn't "frozen" and I can still control with the steering wheel. It even recognises when I move my hand close to the screen. Sometimes switching the infotainment system off and on fixes it, sometimes it needs the ignition to be switched off and on.
Photo of system attached.
I think I'll see if I can get an update for free during the next service. I bought the car in the mainland UK and I live in Northern Ireland so I can't take it back to where I got it!
