How to troubleshoot a unresponsive touchscreen in Kia Sportage?

I have noticed that my Kia Sportage's touchscreen has become unresponsive. What steps can I take to troubleshoot and resolve this issue?

First, try resetting the infotainment system by holding down the power button for 10 seconds. If that doesn't work, check for any loose connections or damaged wiring.

Another possible solution is to update the software on the infotainment system. You can do this by connecting your phone via Bluetooth and going to the settings menu.

If none of the above solutions work, it may be a hardware issue. In this case, I recommend bringing your Kia Sportage to a certified technician for further diagnosis and repair.
