TT7 is only available to the UK Users for now. They have released TT7 though, and you can download the US & Canada map instead of getting the Europe map and paying for it. It's a nice handy tool. I have a tomtom one xl that i'm getting ready to sell. It's of no use and no way am i paying for a new map, especially since the update intervals are crap-pee.
