I didn’t have any issues with the nav/com. There was a little static with the old portable sigtronics intercom that was in the airplane when two headsets were plugged in. Nav/com operates perfectly.did you resolve the issues you had with it?
I was referring to
"The Narco Nav/com works okay, however the com isn't very clear and uses a ton of juice on transmission"
Im looking for a used nav/com with GS but I don't want to install one and have issues that could be costly to repair.
