The WX and traffic function fine in the configuration.
If I change the rs232 from garmin instrument data to aviation, then the HSI on the EFIS works correctly.
The trouble also extends to the autopilot soft keys on the EFIS. While the GDL is configured to work, the nav and apr mode soft keys are grey and not selectable.

Hello Jim,
It is very important that you know what is connected to each display RS-232 serial port and only select the correct format for that device. There isn't much value in just changing serial port configurations to see what happens.
You mention using "Garmin Instrument Data" above, but unless you are connecting a serial port to a GMC 305/307 or GSU 25, you will not be using this format.
Here is a partial list of devices and the RS-232 serial port format that is used for each:
GDL 39/39R: "Garmin Data Transfer"
GNS/GTN: "MapMX"
GMC 305/307: "Garmin Instrument Data"
GSU 25: "Garmin Instrument Data"
SL 30/GNC 255: "Garmin VHF Nav/Comm"
Vizion or GX Pilot Autopilot: "Integrated Autopilot"
Since you are using an RS-232 link to the GDL 39R, make sure and don't also use a Bluetooth link to the same display.
One more thing to check. If you are using a third party autopilot such as this, make sure that the LRU Configuration setup page indicates that you have NO servos since this page is referring to Garmin servos as indicated in the installation manual.
Let us know if you have additional questions.
Thanks,
Steve
