Hi I have a problem with my GTN750 version 2.16
I cant put a frecuency in com1 stanby because it changes in less than one second to 128.250
if I use the default radio in any FSX airplane, I can put the correct frecuency in com1 as stanby or as an active
but If I use the GTN750 the frecuency changes immediately to 128.250
my gtn750 is the complete version , this is happening with the version 2.16, version 2.15 was perfect.
