My marine echomap unit can import .gpx files and .adm files from the SD card. I am currently using homeport to change names and icons, and I am wondering which format conveys the most information to the unit. Obviously the name/lat/lon are there either way, but are other details lost in the export process if using the "inferior" format (whichever that may be, I don't know...)
Do Garmin products have any sort of logic on displaying waypoints in a crowded screen? The waypoints I make offshore with short names and fish icons always seem to get hidden under the mass of existing waypoints... If there was a capitalization/numbering/special character or special icon that gets placed on top of other waypoints/labels when things start stacking up, I'd sure love to know about it! (I have already started using "symbol only" in homeport to de-clutter, but I don't think my echomap unit recognizes that feature)
Thanks!
