hey all, this is my first post, looked around at the other forums and this seems by far the most comprehensive one to join

..
anyway my problem is this.. for some reason the link to the tomtom software has disappeared off my today screen. i cant find a way to re-add it in settings of any sort on the today screen.
do i have to reinstall tomtom for it to reappear? and althou its off topic for this forum, do i have to re-enter any serial key for tomtom if i DO have to reinstall? ive lost the packaging.
thanks in advance,
chay
