I've tried all the different methods out there for trying to fix my 720. So when I turn it on i get the tomtom logo and then the green screen with the 720 on it and the blue 'disk spinning/working' icon in the corner. When I try to connect to my computer I get the same picture except there is the red X through the 720. The only way to turn it off is to reset. I have done the soft and hard reset and neither has helped. So I cant use home to restore and I cant go through windows explorer to manually delete files. Any one have any experience with this problem? Thanks for the help!
