Thought I'd give the new canard zone a try...

Geez - please just use canard-aviators and/or the COZY mailing list, or the canardzone via the forum interface. How many places do we have to monitor to discuss canards? It's already ridiculous...

Here's my question:  The Xponder wiring diagram also shows an optional GPS data input to the Xponder that I've not wired yet.  Does the Dynon Xponder 261 get it's GPS information from the HDX (which most definitely has the GPS wired to it) over the HDX<->Xponder serial port, or do I have to wire this external GPS input in addition to the HDX serial lines to get the full benefit of GPS over the ADSB-OUT functionality of the Xponder?

The SV-XPNDR-261/262 chapter, page 11-11 of the Skyview Installation Manual clearly addresses this question. You don't have to wire the external GPS input if you have the GPS-2020 installed.
