Hi
Please help I have a AF3400 with a garmin 296 and a garmin 420 connected. ( I have a toggle switch so as to choose which GPS data is being sent to the EFIS)
The EFIS is getting all the GPS data (checked and both GPS units info is being sent to the EFIS when toggled) .
The issue is that all of a sudden the wind direction arrow has disappeared. I have checked in the settings and WIND is turned ON.

Not sure what else to check.

thanks in advance
