Neat add on for a cool radio.
Crutchfield Customer Review (What's this?)
Turns your car radio into at detachable multimedia tablet. You can play music or movies stored on an attached sd card or usb stick. It has a usable speaker also. It comes with ac and dc power cables, ear buds, and a neat usb and 3.5mm audio combo cable.
Pros: You can use your car radio in another car or in your home.
Cons: Wish it was battery operated too.
