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.

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


Folks on Cessna Plots forum have had good luck with this:

and also a similar device available from RatShack

Radio Shacks is cheaper but requires adapters:
http://www.radioshack.com/product/in...entPage=family
Ground Loop Isolator $16.99 Model: 270-054

You'll need 2 (depends what you're adapting to) - RCA Female to Mini
Stereo Male adapters Catalog #: 274-883 $5.99 ea.
http://www.radioshack.com/product/in...entPage=family

Cheaper here ($2.38 each):
http://www.valcoelectronics.com/Merc..._Code =18-008

ES-034 The ES-034 isolates multiple components to prevent ground loops.
It may be used as a trouble-shooting installation tool, to break grounds
without removing grounding parts. The ES-034 is designed to interface
with line-level outputs and is equipped with two male and female RCA
jacks, for interconnection with cable adapters/components. $14.00
http://www.buyreliant.com/caudio/noise.htm
http://www.valcoelectronics.com/Merc...t_Code =ES034

So you'll need one of these (Stereo mini to dual RCA male $3.58):

replying to myself

From Garmin's web site today:

Changes made from version 2.70 to 2.80:

* Improved behavior of audible terrain alerts when operating near airports.

....

Thanks, Garmin!
