I am just curious, please don't take my question the wrong way, but why would you need a screen protector for Sensus?
My 2 previous cars, Toyota Camry and then Sienna, had also touch screens and built in navigation, now I have the XC90, but never really thought about the need of touchscreen protector in the car. I always buy screen protector for my iPhones because I refuse to keep them in a case, but that is different story, you are not going to accidentally drop the car navigation on the floor and there is no car key to scratch it
