How do you unlock the F1 Racer on Burnout Paradise?

I know that you need to have a burnout license to get the F1 car but when i type 'walmart' into the code thing it says none found. I also think that you need a PAL version and i am not sure if i have got that, i am from england.|||being from england means u got a PAL version of the game, walmart only works on NTSC, alternatively we have a gamestop car B179 8M20 XA09 80FF


and a pre-order car "Z891 4K88 IN25 79AA"|||l-Mart F1 Racer





Enter "walmart" as a case-sensitive code in the North American version of the game to unlock the Wal-Mart F1 Racer. But you must have a Burnout Paradise license to use this car.
