You can click on SHOP above and see the ADS-B devices Adventure Pilot sells. As far as functionality with iFly GPS, they are all the same. You connect via WIFI to the device and receive NEXRAD, Metars, TAF's, TFR's, wind, pilot reports, and some traffic. With ADS-B out, you will see all the traffic and with only ADS-B in, you will only see some of the traffic.
There is really no reason for AP to add another section to the forum. If you have questions as they relate to ADS-B and iFly GPS, ask them here. If they are specific to the ADS-B device, you probably should go to their forums. For instance Don has a forum for his SkyGuardTWX.
