If you're a fan of in-car entertainment systems like the Ford Sync, then you will love, and I mean love Mini Connected. Mini Connected is Mini's iPod/iPhone integration system that promises such things as a streaming RSS feed and a customizable playlist to match your current driving style.
Mini Connected will be able to connect to your Apple device and stream music off it to fit your current driving style. Facebook and Twitter will also be supported, although I don't know how safe an "I'm driving!" tweet would be to send.
