You can also move the cursor to the same coordinates and use the MARK button to save a waypoint, but manually entering in the waypoints either on the unit or through HumminbirdPC are the only ways to do this. If you have more than just a few waypoints you may want to consider importing them in HumminbirdPC and uploading them to an SD memory card and installing them that way. How many do you have and are these in an electronic format like from Google Earth, off a web page or maybe in a document or spreadsheet that you have saved on your computer?
