You should be able to get one through the dealer, but it will cost you an arm and a leg. I know some people are selling DVDs on ebay. I also have a 2012 and was thinking of trying one of the ebay discs. I've been trying to find info to confirm a DVD is the correct way to update, but haven't been able to find anything yet. I know we don't have the micro SD slot. Those are on the '14+ model years.
