Unfortunately, the EAA STC for the EFIS-D10A only covers the EFIS-D10A itself. Some of the accessories, like autopilot, connectivity to other devices via the HS34, etc are not permitted under that STC. Our Dynon Certified STC for Dynon SkyView, which includes and EFIS-D10A as a backup, does allow for connection to devices like the 430W.
