I am trying to be able to switch from the GPS COM1 to COM2 radios just below the GPS. I can change frequencies ok …but cant isolate a COM2 when needed…I have the latest update for the 206…
I have already answered you on our Discord channel where you asked the same question but didn’t wait for a reply. I mean I answered in 5 minutes. What else can we do! 
Audio panel functionality is coming in a later update after the floats update. You can tune Com2 and Nav 2 independently now.
