In addition to the above, for HARDWARE, do you have the below for the extra running SOFTWARE?
Do the Dual XGPS170, XGPS170D, or XGPS190 ADS-B receivers work with ForeFlight Mobile?

Beginning with ForeFlight Mobile version 10.0 you can use a Dual XGPS170, XGPS170D, or XGPS190 with ForeFlight Mobile, provided you install and use the Dual ADS-B Status Tool app. The Status Tool app is available from the Apple App Store: DUAL Status Tool App
See these DUAL instructions for complete details about configuring the Status Tool app to allow the XGPS170, XGPX170D, or XGPS190 to work with ForeFlight Mobile.
Pair your iPad or iPhone with the XGPS (or connect, if previously paired)
Open the Status Tool app
Tap the "Setup" (gear) button
Turn the "Support ForeFlight" switch ON
Tap the "OK" button
Leave the Status Tool app running in the background, then switch to ForeFlight Mobile
