I have a nice stereo system that can dock and charge an iPod Nano 2nd generation.
I also have an iPod Touch 4 and a 6th gen Nano (or something).
The old docks charge using the firewire pin out and the new ones with the USB power pin out (if I understand correctly).
my google-fu is failing to find a dock adapter that will swap the pinout so I can dock my newere nano into the older dock and play and charge. (It plays now but won't charge)
Is anyone aware of such a product?
