OK... I finally found some. Here's the GTN Map screen, with data fields in all four corners plus the transponder controls but NOT the remote audio panel controls:

Also, it's worth noting that those "Extra" four fields are present on any screen, while the four that are in the corners of the map are only on the Map screen. For example, here's the Weather screen:

And the traffic screen:

Now, here's a couple of fairly similar views of my yoke horn that I pulled from other shots - One shows the whole thing better, one is closer, sorry for the poor quality:

The darker red button on the closer face is the Push To Command (you can see the "PTC" label on the part facing the pilot). Electric trim is easily visible. The CWS (Control Wheel Steering) button for the autopilot is just behind the trim switch, and the big red button above that is autopilot disconnect.
What's more difficult to see is the PTT that's on the front of the horn (though it is just barely there, visible in silhouette if you look at the red master switch) and the Speed Brake switch is not visible at all on the left-hand side of the horn, though you can see the label for it underneath the CWS.
It's a lot of stuff on one horn, and the shop told me that they can't fit anything else in there, but the capability all at your fingertips there is pretty impressive IMO.
