TomTom multisports cardio watch went crazy and cannot use it. As soon as I get it out of charging the screen starts changing from one place to another and won't allow me time to set anything. Cannot use it in any way, tried to reset using the instructions on the page and did not fix it. Any help pleasee, finally Im using it and really need it. Since it is changing screens all the time eats the battery really fast without using it at all. Nothing works???Helppp'.
