How do I fix the touchscreen on my Audi A7?

I've been having trouble with the touchscreen on my Audi A7. It doesn't respond to touch input and has become completely unresponsive. What could be causing this issue and how can I fix it?

First, try restarting your car and see if that solves the issue. If not, it could be a hardware issue, in which case you may need to take it to a professional mechanic or dealership.

Another potential solution is to check for any software updates for your car's infotainment system. Sometimes updating the software can fix touchscreen issues.

If neither of those solutions work, it could be a hardware issue. In that case, I would recommend bringing it to a certified Audi dealership for further diagnosis and repair.
