Selling my boat tomorrow and need to transfer all my waypoints to my desktop (or whatever is easiest) from a Humminbird 898. I also have a Lowrance Elite 7 that I need to transfer. I have a Navionics Hotspot SD card in the 898 that I removed. The Lowrance has a port for an SD card, but I never put one in it. Does it have all the waypoints in it or are they actually in the unit itself. Want to sell the boat...not all my spots! LOL. Techno dummy reaching out! HELP ! ! !
