I am considering going to a Hummingbird Helix 7 with a Lakemaster chip from an older Hummingbird model with a Navionics chip. Is there any easier way to transfer all my waypoints other than entering them one by one into the new chip. Also, I haven't checked their website thoroughly, can I connect the Lakemaster chip to my computer and enter them there like I could with the Navionics software?
