I have a datafield which makes a direct connection to an ANT foot pod. Garmin never auto-migrated this to the VA3 so I recently added this product manually but according to user feedback it doesn't work. The same user says it does work on an Edge device he also has so I am fairly confident he is setting it up right.
Is there anything different in the way the VA3 handles ANT+ comms compared to other Garmin devices? There is nothing I can see in the documentation but I am starting to think there is a reason why Garmin never auto-migrated my datafield for this device.
