I want to know if when using Garmin Glo with the IPAD, once the bluetooth connection is established, the IPAD uses automatically the information from the GLO. Apparently there is no way to know it. I will test it flying over the sea, with the barometric altimeter calibrated (my airfield is at sea level) and test if I get differences.
