Moved my original Helix 10 to the bow and Trying to load my waypoints from that unit to my new Mega unit mounted at the console via SD card and it is reading “not enough memory for all nav data”. I only have about 750 waypoints in the unit that I’m trying to transfer from. I checked the card on humminbird pc and they are downloaded, but can’t understand why they won’t upload from the card to the new unit. Even went and bought a new card in case the one I had was bad.
Any ideas?
