I have had the Harman/Kardon Drive+Play installed in my car for all my iPod products. People told me that it wouldn't work with the iPhone, but it actually worked fine with my old iPhone. It played my music, with minimal interference, and it charged the phone. To my surprise, it does everything but charge the new iPhone 3G. Does anyone know of some cool Transmitter/charging systems that will work with the new iPhone. I'm pretty sure someone has. I can't install any OEM interfaces like the iSimple because my car has the in-dash disc changer.
