Waypoint backup

I have Hummingbird (one on console and one up front--seperate tranducers) both have Navionics card plus blank card

Can I back up cards so I don't lose waypoints---I have put both in my PC--can't see or save anything-----HELP

Yes, just put an SD card in the second slot and you can back everything up. I can't recall the exact settings you go under but it's pretty easy to find in the menu.

Have you downloaded humminbird pc from the hummingbird web site. If so just export to an sd card and put in humminbird pc. There you can save them manage group map ect.

Which Humminbird, it makes a difference in the procedure?

Does Lowrance have a similar software?

yes you can down load on to a SD card
