I just charged my tomtom runner 3. It was at first only showing the time (but incorrect time) and when I charged it wouldn't do anything else and wouldn't sync with my phone. I just tried it syncing with my laptop and now it's completely died - nothing is showing on the screen of the watch at all, so it seems to have completely died and I can't try any of the reset suggestions from the website. What can I do? There seems to be no way of contacting Tomtom directly.
