Well I don't know how the code is sent. My guess is BMW is tired of people illegally generating FSC codes and selling them. Plus they are not selling CD's of the maps for $8 like they did last year as far as I can tell. My belief is they are trying to close that revenue loophole and get $245 from folks because people don't want to pay the outrageous prices they were charging-$400+ . If they are going to close the loophole they might imbed the code inside the map some way.
Not sure how they will do this for when I updated last year from a CD I bought from BMW for $14 I entered a code right at the beginning of the installation. We will see.
