What program can I use that will make a raw backup of the GPS so that I can start over if something goes wrong? What had been happening is the unit would start to drag during a route after a month or so of use and the only way to free it up was to do a hard reset. I had to do this about every couple of months. The last time it did this was about 4 days ago. I tried to do a hard reset after I rebooted, but this time it would stick at the splash screen. It wouldn't go any further than this.
