I have a 2018 with about 23k miles and still discovering things and not. My question is when i plug my phone into either usb port the apple car play automatically comes on and in carplay i'm not able to press the talk button on the steering wheel to ask to change radio channels or text etc. When unplugged i can do these things thru sync. I actually only like carplay for the waze screen to come on the console, other than that much prefer sync. is there a way to be plugged in and be able to do this? really wish they had put a source button on the wheel instead of having to navigate thru the screen. thanks.
