Anyone from Seattle tried this?

I hit Sergej up with my info and he was quick in his response requesting my VIN.

I'm pretty sure I've read each posting on this thread, however, I just wanted to put it out there just in case I missed something.

I'm going to be trying to upgrade a 2009 M3 Sedan with the 2013 mapping software. Any got'chas that I should be aware of? As far as I can tell, I need to validate which firmware version my car's running which should then determine whether it'd be possible to perform the USB upgrade correct?
