Okay thanks, I don't race (yet?). I upgraded to Advance to get some better wind data. It does work but takes several circles to get it going, maybe the GPS signal quality varies allot, (with the banking) etc.
I may go with the Air Connect Wifi device to plug in my C302 data? That way I could move the bad elf pro gps out of my way. Also, I could mount an older 5S iphone where the PNA used to sit. The 6+ is awesome but, but last year I smashed a screen while while setting up my glider. No big deal, $150 and it's good as new.
