I've a Mk4 Monte Carlo with the 9.2 inch infotainment screen. On a few occasions now, I've started up only to find it won't respond to touch until rebooted (by holding down the power button for 10 seconds).

On closer investigation, I discovered that the screen was detecting the touches, but actually registering them at a point half way between the top-left corner of the screen and where my finger was.

This is all very weird and I've not yet figured out exactly what provokes this, but it started around the time I added my partner's iPhone to it (via AirPlay). I usually use Android Auto.

I'm currently thinking software bug. Why consistently half way like that? It's like some UI scale factor is being set that's not properly reset.

Hmm... well it's happened again, even now the iPhone's been deleted. I did have my phone both plugged in and connected by Wi-Fi, though. So I'm still not ruling out some confusion induced by Android Auto.

I’ve just put a post on about the trouble we’ve had today, is that similar to your problem?

Maybe. When you get the mis-taps, is there a consistent pattern to where the screen thinks you've tapped?

I've not seen the problem on mine after disabling Wi-Fi and using Android Auto connected by USB-C.
