As I do not use MyTomTom and this board is really for HOME users I am beginning to struggle however You may want to follow the advice for getting your PC to recognise the device at this link http://http//uk.support.tomtom.com/app/answers/detail/a_id/7375/c/2356 as it should be the same as far as I am aware. If not can I suggest you try the GO1000 live board as the users there will be more familiar with your device and the MyTomTom application. Sorry I can not help you further.
