Will the iFly 720 and 740 pair with a Stratux device?  Here's a descriptive paragraph from a recent EAA write-up found at this link: www.eaa.org/en/eaa/aviation-communiti...
"Stratux works over  Wi-Fi using the “GDL90 Protocol,” a standard data format for ADS-B in  used by many receivers and most apps. For our iPad running ForeFlight,  it was as simple as logging onto the Wi-Fi network broadcast by the  unit, and ForeFlight automatically began using its data. Most apps other  than Garmin Pilot, which exclusively uses a proprietary Garmin device,  have been reported to be compatible with Stratux."
