Hi aruthenb!
Just some research,
Garmin Forum Not familiar but am looking at info. Other than an electronic compass how will it be used to navigate? Can waypoints be installed? I see it can track, but can it project a route? If it can accept a route input can it be done in the field? Does it require a computer/tablet/smartphone to add routes?
