Just updated my e70 maps via a torrent and ping this guy name Sergej via email and he provided me the FSC code and wala.. Updated maps.

I did my update via a USB drive. After downloading the torrent i copied the files to a 32GB USB disk, plugged it in, entered the FSC code and that was it.

The torrent name was this

BMW_CIC_NAVIGATION_NORTH_AMERICA_2013

I hope this helps others
