I updated to v16 software, and that may or may not be related to my AOA no longer functioning (i.e., the red "X" over the graphical display - and, not surprisingly, I no longer get tones or audio warnings). Also, when I recently installed a new 5500 touchscreen (to replace a non-touch), my avionics tech configured all 3 screens to receive ADS-B traffic and weather. Maybe one of these changes impacted the AOA indicator? An ethernet configuration change? See below for my current settings. Any suggestions? Thanks!
