I recently purchased a 2014 328d. The maps were about three years old. My local dealer wanted $200 plus an hour of time for the updates. Instead, I went to Bimmer America. For a total cost of $85 I received the 2016 maps on a flash drive as well as the release code. I plugged the flash drive into the console, entered the release number and 45 minutes later my maps were all updated. Since the cost was reasonable and updating was so easy, it looks like I'll keep my maps updated on a regular basis. Bimmer America mailed the update to me within two days of ordering. Thanks for this alternative to an expensive service from my local dealer.
