"..Only the the connection on C0 is working.."

Do you mean that the first display works correctly (shows Nav1_Standby), but the second does not?
As all connections are as described every display connected to the 0-15 MUX output should work.

Try to connect only one (first) display to the output >0 )

Thanks - Knowing my config and pinout was correct help me eliminate those as an issue. I was able to isolate the issue to a bad wire harness. I suck at wire crimping!

My radio stack is coming along.... Thanks for the help!
