How to troubleshoot a malfunctioning touchscreen in a Vauxhall Insignia?

I recently purchased a Vauxhall Insignia and have been having troubles with the touchscreen. It seems to freeze and not respond to my touch at times. How can I troubleshoot this issue?

First, try resetting the touchscreen by holding down the power button for 10 seconds. If that doesn't work, check for any software updates or try resetting the car's infotainment system by disconnecting the battery. If the issue persists, it may be a hardware problem and you should take it to a certified mechanic.

I had a similar issue with my Vauxhall Insignia's touchscreen. I found that removing the SD card with the navigation maps and then reinserting it seemed to fix the problem. Give it a try and see if it works for you.

I've noticed that the touchscreen freezes when the car is too cold. Try warming up the car before using the touchscreen and see if that makes a difference.
