The garmin homeport is very easy to use. Just drop a pin anywhere on the map and then clic on it to change coordinates and put in things like depth and such. Even has a place to put remarks. Then once you have put all the point/routes in you want just put in the sd card and it will kind of look like windows folders on the left side of the screen. Just drag and copy library to sd card. Then load into garmin and go into the menu and find where it says to import/export and load the way points.
