I will give you a call tomorrow Terry.
I just installed a Garmin GTX-335 replacing my 330ES. My 430 is not a W so the 335 supplied the GPS solution. So now I am looking for a more permanent solution for ADS-b IN to replace my Stratus portable. The Pathfinder seems to fit that bill by putting data on the Horizon WS and WiFi to Foreflight on my iPad.
