I got a G2 vision card today (gift!) and it's just an SD card.
the manual has some warnings about the GPS "can" overwrite the data on the card
& not to use it to back up routes.

It goes on to say "you cannot put it in a pc to view or back it up"

I'm wondering how true that is? Does anyone know if I can make an image (sector
for sector) of the SD card to back it up "just in case" or if putting in a pc
will screw it up?
