Just a little help with the LE mappack

So I own the LE Halo 4 (lucky I know) and I assume that we get the map pack for free right? but i have no idea how to get it.
I have used all the dlc codes i got on my account, except the 14 day trial.
So really my question is How do i get my maps?

Fire up the game, and at the main menu go to the bottom to xbox live marketplace, should then be prompted for the free download.
