Hey Jeremy:
You have a Map76, right? I usually just use the map screen, which shows your position as a triangle in the center of the screen and your waypoints around you that are within the distance you have on the screen. Once you get in the area you are going to fish, zoom out until the waypoint you want shows up on the screen and then move the boat towards the waypoint and zoom in until you're back to 20 or 30-feet on the screen and when the triangle is over the waypoint on the screen you should be over your waypoint and see the cover you're looking for on your graph.
If you want to select a certain waypoint hit "Menu" twice and then scroll down to Points and hit OK. Then scroll to "Waypoints" and hit OK. Then select either "List All" or "Nearest" and hit OK. Then scroll down to the waypoint you want and hit OK. Then toggle over to "Go To" and hit OK and you should have some type of a line to follow from your positoin to the waypoint depending on whether you have your unit set up for "Bearing" or "Course".
