To do a soft reboot of Your touch screen in Your 2018 Jeep Grand Cherokee You'll need to hold down the enter and volume buttons for 15 to 25 seconds. After this time has passed the screen will flash and then it should come back on and work like normal. If the last method did not work for You then You'll need to try disconnecting the battery from the vehicle for 15 minutes. Doing this will have it return to it's factory settings and will unfreeze the screen if it got stuck on something.

My screen was out , but oddly the backup camera worked. It just went black as soon as I took it out of reverse. The soft reboot did nothing, but disconnecting the battery worked. THANK YOU!
