Not sure I know what you are talking about ..... but you can view the waypoints in Google Earth. If you have HB PC open, the icon at the top right allows you to select a single waypoint or group of waypoints and view them in Google Earth.
There's a bit of a glitch on my computer that I get an error message when doing this unless I open Google Earth before trying to view the waypoints in Google Earth. I never have tried to figure out why .....just open Google Earth first.
If you select ...Edit...Preferences ....you can modify the position format to give you the latitude and longitude to fit the format you want.
If you click on the help tab in Humminbird PC, there is a user guide embedded in the software.
