Seriously,though,the manual does do a good job of explaining it.It's just a shame that they don't send the whole manual hard copies (that means in book form for all you young 'uns).The pdf manual is good especially the one that was redone but it would be easier to access in print form.Good luck with your waypoints.
Oh,yeah.Before someone tells you I might as well.There is a search bar at the bottom of the page.Use it before you ask any questions so you don't get flamed.And 99% of the time you will find what you are looking for.
