Here is one of Pioneer's 2012 head units. Pretty nice unit with USB,Bluetooth,HD Radio,CD of course,Aux, and the ability to stream music via bluetooth from Android headunits
....AND now stream Pandora from Android phones! And iPhones of course.
It's a long vid but worth the watch if your interested. Enjoy!
