Newbie question for anyone/everyone here. A group of 3 of us are doing the TAT mid Aug through Sept. We have both Sam's and Kevin's maps. Here's my question...On Kevin's SD card, the trail shows on my Garmin as an embedded line on the map. Does the rider "icon" advance on the gps as if you're following a "track" or do you have to keep manually advancing the map to see where you are? Secondly, are the waypoints for gas, food and other stops "trackable". Meaning can you see how far to next POI? Can't really test it out until we're actually on the trail. Thanks in advance!
