Tried on a flight home from Houston this past week .... as well as here at the house this morning.  I first selected the auto-find function on my iFly 720 ... no luck.  When I go to manual, the Dual does not appear on the list of devices that can be connected.  No luck searching the options in the two set-up menus.
No problem receiving traffic and weather on my iFly 720 with my older stratux.  I just pruchased the Dual XGPS 170D because the iFly was listed by them as a compatible efb.
Possibly because the Dual is blue tooth, rather than the wifi thingy?
Thanks in advance for your help,
