I'll throw out this tidbit so it can help someone else. When I wired up my avionics, I had one serial output from the GNS-430W go to my autopilot and a separate serial output go to the EFIS. I thought that would give me the most flexibility. Turns out both the EFIS and autopilot want the same "aviation" format. The 430W can only output a particular format on one serial output. I'll have to do a little re-wiring.
