Mophie Battery Pack - Music through Micro-USB
I have a Mini Cooper with integrated Ipod package. I currently use it often to play music and to use it for GPS voice instructions. I am looking to buy the Mophie Battery case (or a couple others) while using the Micro-USB to play music.
I have searched for female 30-pin connector to Micro-USB but come up short. Or micro-USB to split 3.5mm and USB, also, came up short.
The micro-USB is not only for charging, you do have data transfer, because it is able to sync that way.
Thus,Is it even possible to get some music output through the micro-USB?
