I have downloaded Mazda toolbox and installed Tom Tom but when I put the SD card into the computer it says its not recognised. I have called Tom Tom whose reception isn't open and they tell people to contact the website. I have done this but cant find any help. I want to upgrade the map and I know I have to pay for it. Does anybody have any suggestions?
