Although I haven't tried it, I wouldn't attempt to back it up. Garmin is
very clear that they will not replace cards that were damaged in this
manner. They are expensive. Your unit will warn you if you attempt to write
anything to the data card... just say no. g

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?
