I recently purchased a 2017 Touring L Plus. The rear seat entertainment screens work using any type of video (blue ray and usb movies) and using the are we there yet app. Any other type of game app (checkers, solitaire) causes the screen to go black. It is not an issue of the brightness turned all the way down (already happened once and I fixed it - not sure why any programmer in their right mind would allow you to completely black out your screen rendering it useless, that's another story). I've downloaded the most recent uconnect update and installed it, still nothing. Any ideas? Or should I take it in to the service dept? Thanks!!
