You might to do it here instead of the 360. Simply Copy and Paste into the Redeem box.
Ah that works even better. Had the old grinder AKA 360 turned on if codes got put up. (My 360 is fuck loud and sounds like it's eating grunts to fuel itself)
I hope they do put up some codes otherwise I'll be waiting a lot longer till I can get those maps.
