1. You will want to use the provided *.usr file for your Lowrance.
2. Any SD card will work, but for some units a card 8GB or less is suggested as some units cannot use the bigger cards. However, my Lowrance Elite 7 works fine with a 16GB card.
3. If you want to edit spots, I suggest you load the KML file in Google Earth and make changes as necessary, and then convert the file back to .USR file for your Lowrance using GPSBabel.
