How to troubleshoot a malfunctioning touchscreen on Vauxhall Crossland?

My Vauxhall Crossland's touchscreen suddenly stopped responding. How can I fix this issue?

First, try restarting the car's computer by disconnecting the battery for a few minutes. If that doesn't work, check for any software updates for the touchscreen. If all else fails, you may need to take it to a certified Vauxhall technician for further assistance.

Make sure the screen is free from any dirt or debris that could be interfering with the touchscreen. You can also try cleaning the screen with a soft, lint-free cloth. If the issue persists, it could be a hardware problem and you should bring it to a Vauxhall dealership for a professional diagnosis.

Have you recently made any changes to the car's electrical system? It's possible that there could be a faulty connection or wiring issue. Check the car's manual for any fuse or wiring diagrams and make sure everything is properly connected.
