AUTOPILOT + GPS GARMIN 496 PROBLEM

[tecnomn]

Respectable Dynon, has done today some proofs flight of the autopilot as soon as installed EFIS D10A + AP + HS + 2 servos, I have programmed 4 points of rout on the GPS 496, distant among them around 10 miles, to 1000 feet I have inserted the autopilot in NAV mode; the airplane is one direct once reached then toward the first point, one is direct toward the second point.  
 
After rather than to direct the third point he has continued law for a rout stranger, I have verified the points of rout in the GPS and correctly arrivals to the second point the GPS has moved the arrow around third point, in the cartography was seen the run that owed behavior, but in practice after the second point it doesn't have more succession the in demand rout.  
 
Have not losses of communication been us of it and formality NAV has remained always inserted, do you have some suggestion??

I think you're saying that at some point the autopilot isn't continuing your GPS route sequence. Is that correct? If so, loss of communication from the GPS can cause it to revert to heading hold mode. Did you notice whether or not this happened?

The problem has been resolved, the parameters of communication were not correct between GPS and EFIS.
