I've bought a GeoNav 3 GPS with Navionics maps and charts of Europe. (secial offer for 249 Euro with Land and Sea charts)

http://www.geonav.it/english/Chartplotters/geonav3.html

http://www.navionics.com/Charts_LandSea....tCode=05LS

The notice on the Navionics SD card said "data on the card will be destroyed if copied with a card reader or a computer"

Is it not possible to backup the SD card? Or have a copy as backup?

Regards
