That way the old map is replaced or overwritten. For instance, I think if I copy updated maps from Garmin Express, and I want to load them on my plotter, I should use "Replace from Card". Like I said, I'm still a little fuzzy on when to use what. "Replace from Card" is designed to overwrite or replace existing data. I'm still a little fuzzy on when to use which function, but I do know that one (Merge from Card) will allow duplication of data, while the other (Replace from Card) will not. "Merge from Card" and "Replace from Card". I think the answer to your problem may be in how you transfer the data from the card to the plotter. I don't know if your cards are compatible with Homeport, I believe you said they are Navionics cards, but it may be worth a try. With a little help from the internet I was finally able to get it saved and merged onto my chartplotter. It's not very intuitive, or maybe I'm just dumb, but I did struggle with trying to save the track I created to the card. I was able to create waypoints, tracks and routes. There was also a button for tidal information, but I didn't play with that. When I clicked on the file, HP picked it up and I could see nav buoys, channel markers, shoals, water depths and so forth. When HP booted up I could see the US Coastal Maps file in the menu. Then I plugged that copy into my computer and started Homeport. But this time I made a memory card copy of the US Coastal chart that was loaded on my chartplotter. In fact, the bayou wasn't even visible on the HP base map. I had attempted this once on Garmin Homeport but wasn't getting the map detail I needed. So I thought it would be nice to create a track on my computer and export it to my chartplotter so I could watch that track, rather than zooming in and out to "look ahead" while we're on the water. Those, along with the natural tributaries can make it hard to know if you are staying in the main bayou at times. The bayou runs through a marsh and years ago the oil companies cut hundreds of canals off the main bayou. I don't know if you ever resolved this issue but I remembered this thread and thought I would share a learning I had.Ī buddy and I are planning a trip to scout a 21 mile long bayou in southwest Louisiana. If you haven't ever messed with it, the settings in GE are under Tools/Options/3D view. I'm not a guru on the subject, but it could be that if you have your GPS set to one format and GE set to a different format, it may cause a conflict. One format reads in deg/min/sec and another reads in deg/decimal minutes, for instance. I know on Google Earth you can pick/change the format of your coordinates. But GE at least has the landmass features in fine enough detail for waypoint creation. The nautical data, like depth references, or landmass features, like points of land, are just not there or are not detailed enough for that. The default HomePort maps are not detailed enough, in my opinion, to create accurate waypoints. Now, about all I've done with it is copied Texas Parks and Wildlife Department fish structure coordinates (GPX files) from their website, dropped them into HomePort, renamed them in HomePort and then transferred them to my GPS. gpx files onto my GPS using a memory card without a hitch. Don't know if it will be any help with the nautical data, but I have dropped. But HomePort was a free download last time I looked. I do see where there is an "Import" function in one of the drop down menus that may allow you to import the nautical features from Navionics, don't know. So my map on HomePort doesn't have any nautical data. I use Garmin HomePort for transferring waypoints, but I haven't paired it with Navionics Gold.
