Making the GNS 750 Work with A2A Civilian P-51 Mustang

Hi,

I'm able to get the A2A P-51 Civilian version to follow the "magenta line," however, I'm not able to get the auto-pilot to follow the GPS generated glideslope when executing an LPV approach.

I did set the following variable below = 1 in the aircraft.cfg file to enable the glideslope symbols in the HSI, otherwise there was a green NAV flag showing it disabled:

flight_director_available=1

Any suggestions on how to make this work?
