I am waiting for Nushield to make one for the infotainment unit with the knob.
This seems to be a constant debate. There are benefits to installing a screen protector. The screen can get fine scratches from fingernails, towels, paper towels, dirt on hands, etc. They are very fine and most of the time you won't notice them, but they will exist.
One person dropped their keys and they slid down the screen and caused a major scratch. The material used for the screen is not as tough as the gorilla glass or other material used on cellphones.
I always purchase a screen protector.
