Can't speak for the '13 M3 or the new Nano. I keep a dedicated Nano (older gen) in the center console of my 2011 M3 and it stays charged through the white iPod cable plugged into the USB port.
What I am not sure of is the lightning/USB cable. I would think the Nano would charge just like mine does but I cannot confirm this...
Thanks for the reply! The dealership is now telling me the same thing, no additional equipment needed.
