I tried to buy the 7.2 Canada-USA map for my TT ONE XL and couldn't because I have a 'Canadian account' and my credit card 'will not work' when making US purchases!! What a bunch of bunk!! This is really poor of TT...why sell the device in Canada and then tell people that updates are not available...and no solution to this problem in the near future!! Has anyone else had this problem? If so, how did you get a map update? Thanks.
