Still no luck with Windows recognizing the device as anything, not a gps or a usb mass storage device. I did run check on it and now I have 2 gb of free space. I am still mystified where the other half gig went. THis happened the first time I tried to update my maps and I'll be damned if I can remember how I fixed it. For now I'm going to get the lower 49 state img and call it a day, as its five o clock and I'm wasting good beer drinking time.
