No wireless charging?Apple is releasing the new ios 7 in the fall. They announced a new feature called ios in the car. It links the iphone to the car's infotainment system and let's you manipulate navigation, messaging, among other functions. Mercedes is one of 14 automakers involved so far.

If they didn't, it would be great if they did. I can see a big demand for that as it's much easier to rest your phone on a pad than mess around with a cable in your car that can at times get in the way of things like the shifter.
