I've been using TomTom 720 for a few weeks. Usually when I plug into computer, I can contol TomTom by computer. This morning it told me to update home. Since I updated, I can no longer control TomTom by computer.I updated to 2.2.2.83. Anyone know how to get back what I had, or, why this "new" home won't let computer control TomTom?
