View Full Version : Updated GTN software, now AFS4500 says no GPS

I just updated my GTN software because it was not working with my updated GTX330ES software. Now I get NO GPS is on the AFS 4500. Is there a compatibility issue with GTN 650 Software Version 6.41? The 4500 has Software Version S8.8.35-MV16. Do I need to update it?

On the 650 when you setup ADS-B+ on Serial 2 to the 330ES did you leave the Aviation Output 1 on Serial 1?

I’m not sure which setting I changed that fixed this problem as I was working another issue, but I’m happy to say both problems are fixed. Thanks for reaching out to me.
