System components: D-1000T dual screens, aads-b 2020, GTR200. GNC355,GMA245, ARINC429,dual ADAHARS,
Questions:
1.can Skyview push radio freqs to GTR200 and GNC355.
2. Can the GMA245 be used as switching device for active radio display on skyview screen?
3. When using gnc355 as nav source is the skyview CDI and vertical position indicator displayed for GNC 355
Thanks in advance for any guidance you can provide!
 
Following as well. I believe it can push the freqs to the non dynon radios. Not sure about the other 2.

1) Yes to the GTR200, no to the GNC355
2) No - the GMA switches the audio signals, the serial signals are not nominally switched at all
3) Yes, you can switch the HSI source between any connected nav/gps source, or SkyView's own navigation flight planning, with the touch of a button.
 
How does the Skyview HDX push Radio freq to the GTR200? You can provide a wiring diagram?
 
Via serial port. See the Dynon Installation guide. The GTR200 is very similar to the SL40 in this regard.

So the GNC355 will feed full GPSS capabilities to the autopilot similar to the GNS430W? I'm intrigued to see that in the Q&A section of the Aircraft Spruce web site's GNC355 page it mentions this:
Q: Can the Garmin GNC 355 be connected to the Dynon Skyview Classics CDI?
Per the manufacturer, no they will not work together.
Would the answer be different with the HDX?
 
So the full answer is more nuanced.

The GPS side of the GNC 355 works just like other Garmin GPS navigators, and can be connected via ARINC-429.

The COM side doesn't work the same, from a technical interface perspective, as the stand-alone COMs.
