I just got the Edge 705 back in the fall. I've used it a half dozen times mostly tracking my ride data and then loading it to trainingpeaks. I know there is much more functionality to this unit and I have much to learn. The next thing I'd like to attempt, if possible, is to load a map of a trail system and use it to determine where I am if I get lost. Is this possible? I figure if I carry the paper map and then reference the Edge for my current location I should be able to find my way.
