I don't understand why this is so difficult? CarPlay/Android Auto make the most sense, but if not those... why not make the Lexus screen capable of mirroring a user's cell phone screen and add Lexus input functionality to select icons/type/play/pause etc? Bonus: the cell phone and Lexus input system could govern the cell phone (and by default the mirrored screen) which would increase ease of use and might be fun for everyone in the car (particularly for someone in the back seat who gets a shot at controlling the music playlist, finding a restaurant, using Apple/Google maps that will never be outdated, etc). OK - we need a code to prohibit playing movies unless the car is stopped but you get the picture. I bought Apple TV years ago for under $100 and can turn any screen in my house (including a dinosaur TV) into something great by mirroring my iPhone/iPad. We already have the technology, why not use it and skip apps like the Scout GPS link (which seems to have been developed before the turn of the century).
