I won't be installing this for probably a couple years... but for planning purposes... I have a Microair m760. It is an older version. REV N. How are the built in intercoms on these? Would you use it or buy a stand alone intercom?

If I recall, I believe that Tony Spicer had one in his Sonex and in his video he mentioned that the radio itself is great but the intercom is not voice activated. You need to have a switch for it, and when you want it on flip the switch, and then off flip it again. I put a FlightLine radio in my plane and even though it too has a built in intercom I chose to install a FlightCom 403LSA intercom because I thought the $194 would be worth it, plus I really wanted to be able to hook up a music input into the intercom.

Thanks for the reply. I also want the music input. REV N does not have the input muting on com receive so that is another issue. Actually the input pin is not even used and the music input is wired in parallel with the headsets.

I thought about trying to make my own input muting circuit as a side electronics project. Could be a good learning experience. But at $194 the flightcom is probably the way to go.
