When I go to configure the 430W and the SV-GPS-2020, do I just connect the 430W to another Serial port and the 2020 to Serial port 5? How do I choose which antenna will be the default for navigation?
2020 to Port 5, 430W only to the Arinc Converter as per the install manual including the diagram - please read it as it’s very simply shown. BTW, you have downloaded the latest version ?
