Hi All, Just Wonder If Anybody Can Help Me With This. I Have A Tomtom 510 About 3 Years Old No Warranty. Was Working Fine. But Suddenly It Stop Working. If You Press The Power Button On The Device It Doesn't Power On. When You Put The Main Charger On It Only Shows One Green Light On On The Device. Can Any Body Advise Whats Wrong & How To Sort This Out. Any Reply Will Be Highly Appreciated. Many Thanks
