Seems there's a USB input somewhere on my 2011 S4 as in the menu options there is the ability to update via USB. I'd love to be able to charge my BB via USB, so was curious where this input was on the car? Can't seem to find it in the manual or by looking around!

 

No USB, to the best of my knowledge unless you buy a USB adapter and plug into your ipod hook up in the glove (if they sell a USB adapter, I've never seen one)
