ADS-B traffic not displaying

[boneflier]

Though the ADS-B Traffic display says "OK", and the CHECK>ABOUT>WX shows traffic message counts, they are not displaying on the map nor on my iPad with Foreflight that is connected via the AFS WiFi. It used to show this, so is there a setting somewhere that I might have inadvertently changed?

Traffic can be disabled using SET -> MAP -> TRAFFIC. This will also cause an alert to present. My best guess is that the EFIS -> ADS-B serial connection isn't working. This carries GPS position back to the receiver for it to actively filter the traffic by location.

How do I check to see if that is the case?
