I've got a Garmin speed sensor that every once in a while seems to get confused and reports weird speeds. In the past I've seen it when the battery was low, this time it was when I swapped wheelsets on the bike.
Is there any way to show a data field on the Edge that shows speed from the GPS even when a speed sensor is connected? Just so I can have a diagnostic page to flip to and see how the two compare? As far as I can tell, when a speed sensor is connected the Edge doesn't care what the GPS calculated speed is anymore.
