I'm using Car Play, with the phone plugged into the usb on the dash -- which is the only way it will work. Shows me when a message comes in, and when I select it with a tap, Siri reads it to me. Excellent integration, IMHO
I have apple carplay in my 2015 subaru forester xt, every once in a while the iPhone wont connect and just requires a phone reset. Mine will read and send text messages all hands free without the need to connect the phone to the iphone cable.
