I have a dual screen g3x classic panel with tt gx pilot, gtn 650 and no GMC 305. After entering and activating an approach when can/should you enter ap appr mode? My system seems to be working but after loading and activating an approach I don't get the "ap appr" soft key when pressing the alt/pitch soft key.
