and then a Garmin Colorado 400c handheld that lives in the Ditch Bag, also an older eTrex in the Bag as well. For the Garmin 440, I have it set up for quick connect / disconnect using an Edson mount that fastens to the top of my Pedestal Guard w/two allen screws, I fitted the power cord from the 440 to a 12V plug that we plug into a 12V receptacle just inside the companionway. The Garmin 440 is loaded with East Coast charts and Explorer Charts for the Bahamas. The Helm and NAV Plotters/GPS are older Raymarine Pathfinders. Cheers, John
