Wow, i did not see this coming for several years. I have been holding off buying a new NEX unit trying to figure out how to get a very clean look with all the cables required for car play, app radio, usb, aux etc.. At least this will eliminate one of the extra cables. What can you say it is technology and it keeps getting better. This might be all the hold up with some of the auto manufacturers knowing that the wireless mode is coming and they held off putting it into the new cars.
I figured the lightning cable approach was due to battery drain and a seamless experience.
