Nomad110 Posted May 8, 2013 Report Share Posted May 8, 2013 Hey guys, I'm hoping someone here may have run into this problem. I am looking to install a GMA35 with my GTN 750 in the EC-130. Garmin's site clearly explains that the GMA35 is capable of "Six/Seven position intercom: pilot, copilot, four or five passengers." But what I don't understand is the unit only shows 6 possible physical headset hookups. I don't want to run a mic in parallel for obvious reasons so what is the right way to get that 7th connection Garmin refers to. Has anyone dealt with this? Thanks Quote Link to comment Share on other sites More sharing options...

Nomad110 Posted May 11, 2013 Author Report Share Posted May 11, 2013 I figured it out.... Not that anyone seems to really need this information considering it's kind of esoteric but here it goes... In order to make this work Garmin wants you to parallel the 5th headset and wire the mic into the module 5 on the GMA 35. Then a special software file is sent to you from Garmin that enables the module 5 to act as an audio receiver and configures the GTN 750 to know what to do with it. I'll let you know if it works.
