Is there a separate wearable Garmin GPS unit that would sync with a fenix 5?, like a tempe does for temperature?
This would be very desirable for when following running trails or running "track-back" on a trail, or hiking when there's
not much daylight - when a wrong move could send you over the edge of a cliff, or down the wrong trail for a distance.
