I have been watching some videos on YouTube and Vimeo showing the Garmin 750/650 navigators in flight. I started noticing that some of these videos contained full cockpit audio and I started hearing annunications concerning terrain and other things like traffic. Even when I am playing around with the GTN trainer, I am getting annunications (see the pictures below).
For those of you with the GTN series, are there annunications coming out of your units and being fed either into the audio panel or the overhead speaker? If so, what are you hearing?
