You no longer can upgrade your older gt fore games to the complete version..ITNET is no longer...for many...many years actually..you will have to buy the board and HD inorder to get the complete. I know a guy that has 40+ complete board sets of the green board..he sells them on ebay for $430 bucks...but i think you might be able to haggle down that price. If you want his ebay username, pm me and i can get it for you.
