just got a garmin etrex vista cx. I am a complete novice I am having trouble getting started the manual doesn't realy show what to do as far as doing things such as parking your truck going in the woods and finding your way back. I understand how to start a waypoint at the beginning by pushing in the thumbstick and pushing it in at your destination or other points of interest, But I don't understand what to do to go find it. Do I use the compass page?? I understand if I hit go to it just shows a straight line to the waypoint flag. Ther is a video from garmin on this unit Does anyone know if this is anygood?? If someone could show me step by step on how to start I could probably get the other things going Thanx
