I recently purchased a Garmin Echomap plus 93SV and I love it so far but Im wondering if I could transfer my waypoints from my humminbird to the GArmin unit? I have them all on my Humminbird PC and could put them in a spreadsheet to copy and paste if needed but I dont know if Garmin has a way to save waypoints on an SD card using a PC oir if they can be transferred through Active Captain. Any help would be appreciated.
