Can I use ForeFlight with a Garmin GTX-335?

The GTX-335 ADS-B Out transponder does not have Bluetooth connectivity so it can not directly connect and send data to ForeFlight Mobile. The GTX-335 will work well in combination with a dual-band ADS-B receiver such as a Sentry or Scout portable ADS-B receiver. The GTX-335 provides ADS-B Out, while the Sentry or Scout will let you view ADS-B In data (weather and traffic) in ForeFlight Mobile.
