I had the same problem and found out that I didn't have the weather turned on. Across the bottom one of the buttons (weather) allows you to select which weather you have and turn it on or off IIRC. The set button may have to be pushed to display the correct menu across the bottom. I am not at the hanger or I would walk you through it. This of course assuming that you have the serial port set up for the ADSB correctly. Something to look at anyway? Larry
