Weirdest thing. I have a garmin 650 running GPS info to my GRT Horizon EX. I have a switch so I can pic which item guides the autopolit, the efis or the gps. A few flights ago my GRT stopped giving GPSS steering commands to my trutrak vz385. If I switch it to the GPS I can get GPSS steering. But for some reason it went away when commanding it from the efis. Any ideas why this setup, which has worked perfectly for the last 10 months all of the sudden go TU? Is it possible my ARINC module went bad? I'm also afraid that once it happened I started messing with settings to get it to work and now might not have them how I had it configured. Here is a couple of screen shots of my settings. Any help you could give me would be greatly appreciated!
