I have a Magellan GC and cannot get it to work with Windows 8. The Staples "geek", after spending 2 hrs trying to upload my GPS, got the GPS upload caches for about a day, but the GPS kept crashing. I needed to remove it from the USB port and plugging it into the UPB port. Now it doesnt work at all! I am so frustrated, I want to wipe the Windows 8 off the computer and replace it with Windows 7. I called Magellan last night. They said that sometimes the GC works on Windows 8 and other times it does not. They said that it is all GPS specific, and not sure why some work and others don't. I LOVE my Magellan GC's paperless system. Help!
