I've read the manuals and searched as much as I could, and still have some questions about the Skyview system and how it relates to other avionics.

I plan to install the complete STC'd system (10" Skyview, D10A backup, autopilot, AOA, etc.) in my Cardinal when it becomes available and would like to be able to use the GPS or NAV output from my #1 radio (Avidyne IFD540), or the NAV from my #2 radio (Garmin GNC 255A) to feed data to the HSI, HITS, Flight Director bars, or any navigational display on either the 10" Skyview HDX or the D10A.  Example: I'd like to feed the #1's LPV approach into the Skyview DHX, and the #2's ILS approach into the D10A.  I'd also like to use either the #1 or #2 navigational outputs as the Dynon autopilot's source.

Are these things possible?

Yes
