If you got lucky and the car sees the USB stick, then buy an FSC code from Sergej and you're good to go.
I have a 2011 328i CV. I worked with Sergej and got the FSC code and downloaded the 2013 Map update from Torret. I am puzzled and need more ideas. The USB is not recognized so it does not get to the part where it asks for a FSC code. It is interesting that I can see the file structure on the USB from the Media CD/DVD view (Like I am going to select a tune to play from an aux device). It appears to have the larger Premuim Screen. Any other ideas?
