This is not exactly correct, your avionics guy was trying to use the DRX as the GPS data source for the EFIS and I told him that would not work. The DRX would have worked to get ADSB weather and traffic on the EFIS. The most reliable way to get ADSB data is to use our wired Dynon SV-ADSB-472 receiver. The AF-5000 has 5 RS-232 serial ports, same as a Dynon Skyview. Email me a list of your current EFIS serial port settings.
