I have a 2010 and I ordered the map updates last year. When you order the DVD they ask you for the Application Number off of your Nav head unit and they send you an unlock code that is tied to that number. I had my head unit changed under warranty and it took a bit of doing to get a new unlock code so I could reinstall the maps. I don't think the DVD is specific to the vehicle, but without having the right unlock code generated for your head unit the discs won't do you any good.

From Navteq's website:
* The Application Number is a unique identification number from your navigation system that is used to generate the activation code. To obtain the Application Number, press the Information ("I") button located in your vehicle and then select "System Info".
