The 340 installers manual talks about a signal line on the back of the unit
that disables auto mute. Did Garmin tell you that this didn't work for the
pilot ?


Garmin explained it to me as follows: The GMA340 has two aux inputs.
One input serves all intercom stations and one input serves just the
passengers' station. The auto-mute of the input when receiving a radio
transmission cannot be disabled for the input that serves all stations.
The auto-mute can be disabled for the second input.

Believe me. I *really* wanted this feature disabled when I first bought
the aircraft that was equipped with the GMA340 (last year) and had asked
everyone involved if this was possible. When I learned it wasn't, I
actually considered replacing the GMA340 with PS Engineering's
Garmin-compatible audio panel and selling the GMA340 on eBay.



Ah, I stand corrected. I assumed you had not read the installers manual.

I'm sad, I had been planning to do that as well. The problem is not just
having or not having the controller blanked out by music, but having *anyone*
in the friggin' cockpit turn it off by coughing.
