Hello All. I am a rookie at this forum but I need HELP. My TomTom stopped working yesterday. After a 5 mile run it just stopped working. Screen went blank and did not respond to anything. It had been on the charger all night so it was ready to go. I tried the DOWN button with a hard reset without any luck. Is it officially dead? I am in training with 6 weeks to go for my half marathon.....can't imagine not training with my watch. Any advice is welcome!!
