I just purchased a Garmin GPSMAP 66s and am in the process of figuring out how best to use it for geotagging landscape photos from my Canon DSLR. I formally used an Etrex 20x but needed a larger screen to view maps. I got a bit confused with the 66s with activities, tracks, etc as to which one to use for this. I think Tracks are probably the method to use because I want to end up with a .GPX file that I can ermbed onto my image file using external software like GPicSync because activities seem to be used for health and fitness uses. I guess I am asking how best to end up with geotagged photos with the 66s so I can tell exactly where the photo was taken. I haven't found much info on-line regarding this subject. any advice will be Jim L
