My V70 has a "Sensus Connected Touch" display, where most functions (radio, climate, settings menu, etc.) are displayed; some of these are operated via a menu dial and/or other, physical, buttons on the dash, but a few offer touch controls -- namely, the GPS and "Connected Touch" functionality (in reality, a ridiculously handicapped Android thing they call "Asterisk").
I don't use the GPS very often (my phone is better), and even the apps (esp. TuneIn) I prefer to operate with the physical buttons. So I don't exactly know when this problem started; I only discovered it the other day when I tried to search for a new web radio station within TuneIn. It's not just that app, though, the problem is present in all apps --- I can no longer operate touch apps, such as on-screen and the virtual keyboard. This makes the GPS completely unusable, and limits other apps to what's already coded in and accessible via the physical buttons.
Now, question time: Is there a "hack" or quick way to fix this, or am I looking at a (possibly expensive) repair job? I've been googling, but haven't turned up any sense that this is a commonly seen or well-known occurrence.
It's been cold recently, I don't know if that's related. I am unhopeful that this problem will "thaw itself away" any time soon.
