Hey guys i need some help with a little problem i am having. i am wanting to install my software updates for my humminbird 798ci hd. I was getting ready to download the software from humminbirds website when it told me i needed to save all my waypoints on to a card or my computer because when i up i upload the software on to the fishfinder i will loose all my waypoints. Now i know how to export all my way points on to a card but i am wondering once i export them to a scandisk card and take the card out of the unit will my way points still be on the unit? also i am wondering once i export them out how do i get them back onto the unit once the software up date is loaded.......i need help please.
