Not in detail, but generally, hit “page”, scroll to the right to the page that has “waypoints,…”, this used to be the “Utilities” page before Lowrance updated it, it may also say “files”, go to “files”, you will get a list of files in the sonar. Move cursor to “memory card”, highlight the file you want, I believe you hit “menu” on the keyboard and it will ask if you want to load the file. “Yes”, you do. The HDS units are not nearly as user-friendly as the others, you have to look in a lot of places and try things to find the function you want. There are user groups on the net that offer tips and I have done searches and found a lot of answers. I forget stuff as quickly as I learn it. The geeks that write code for Lowrance do not use the units, obviously.
