That's never happened to me. I've had the audio connected (listening to
music) and I did have it on during a landing or two. Will try it out
some more.

Thanks, MD. I'd appreciate knowing what you find out. You get the "500" callout
at 500 AGL, right? After that, I get a cacaphony of "Terrain, terrain, pull up,
pull up!".


The prob I've had with the audio is a loud buzz unless I unplug the
power and run on battery.

I don't have that symptom. Sparkchasers put a molex connector right underneath
the yoke so I can connect to ship's power and tie into the audio panel. I'm not
trying to listen to music, though.


Of course, my unit has had problems - sent it in twice. Finally got a
new box.

Does anyone else have their Garmin 396 connected to the audio in their
airplane?

If so, do you get terrain warnings every time you approach an airport
to land?

I do, but Garmin doesn't seem to be very interested in helping. I've
exchanged several emails with their tech support. They don't
acknowledge that there is anything wrong.

They say they have "some algorithms" to prevent the audio terrain
alert when approaching an airport to land. They say they might not
work correctly for all airports. My experience is that they don't work
for any airport I have visited.

If anyone else is seeing this behavior, please contact Garmin so that
they will know I'm not the only one.

Thanks.
