I don't believe the code is tied to the year, only to the VIN of the vehicle. But it is a use once code. I believe you could buy a code this year (2012) but not use it this year. Then next year (2013) you could buy those maps and then use the code. So it doesn't matter what year you use the code on, but you can only use it for one year.
