I have a 2018 Acura TLX which is the first year they offered CarPlay. For those familiar with Acuras, they use a somewhat goofy two screen design. The lower screen is touch, but only controls the HVAC and “infotainment” system. The upper screen in not a touch screen and displays other information such as trip computer, Bluetooth audio, etc. it is on this upper screen that Acura chooses to put CarPlay.
So I have no touch control for CarPlay. It is a matter of rotating a knob and pressing it to select. With what I hear of some people having double with finicky touchscreens, I really don’t mind this input method. I don’t need to concentrate on the screen nearly as much as if I had to tap a button.
That said, my car only allows CarPlay through the USB connection. A friend with a BMW says she can use CarPlay over Bluetooth. It would be convenient to not have to plug in the phone every time.
