Did mine via USB. Got my FSC code from *******, took about 45 minutes to reply to request, got my code < 5min after paypal completed. Half the price quoted by others. Also had a blank version screen until I completely shut off car and restarted. Nothing really different, just updated maps. Worth it to do it yourself, if you have to have the latest, a complete rip-off at the dealer.
