dual ADAHRS and compass cal

[S5_aero]

i have just got the plane after it has got second SV-touch installed and also second ADAHRS.
I loaded my .dfg file as the layout of engine widget was different and after that i got the message SINGLE ADAHRS on PFD and caution button shows NEED COMPASS CAL. the .dfg was from previus version of SV so it showed up i believe 6 items in error, also the file is from single display system and now i have two displays.
I calibrated the compass on groung saved it and the message didn't go away so i went flying and made in flight cal. this didn't help. so on ground i did the calibration again two more times and it didn't go away i did one more in flight calibration and the same.
what should i do?

So it sounds like one of your displays has been in the aircraft and the other is new. In this case, the best way to add a display is the following. Your mileage may vary since you might be in an odd / inconsistent state right now.

-First, before you do anything, perform a settings backup from the original screen.
-On the new screen, set the tail number to DYNON. This tells the system that the screen is new, and when the other (old but correctly configured) display configures the network, it will adopt the new screen with its settings. Don't do anything else on this screen.
-With everything powered up and connected, from the original (old) screen, perform a SkyView Network configuration. This will take all of the good settings, including engine layouts and everything, from the original display and push them to the "new" screen. If this is successful, you should see the new display on the old display's SkyView Network configuration page. You should also be able to exit system setup on the old display, enter it on the new one, and see that the tail number of the aircraft now matches the old display.

After you have the network configured correctly, try doing the compass calibration process again. Because you have a new ADAHRS, you'll need to perform the compass calibration for it. Same for AOA if you have our AOA/pitot probe.

How would you perform a compass calibration for just one new ADAHRS? I have two screens and one of my two ADAHRS went bad so I will have to replace it.

It worked.
Thank you Dynon.

Bob - Whenever you perform a calibration, all compasses are calibrated simultaneously. So basically, just do the calibration - the new compass will get it's first ever calibration, and the existing one will come along for the ride and get re-calibrated at the same time.
