D10A Wind indication

[Orf]

I have a D10A, AvMap EKPiv Pro and an AP74 autopilot all correctly wired together and working correctly. I want to display the wind info on the D10 but I cannot work out why it won't work.
I do not have auto OAT, instead I put the temperature in manually. The input temp, TAS and pressure ALT are all displayed correctly on the D10.
I dug down in the settings on the D10 and found a WIND N setting. I changed this setting to WIND Y but it did not make the wind display on the screen.
Is there another setting that I need to change? What communications setting do I need on the AvMap to make the wind display on the D10?
In replying and you are familiar with these instruments I would appreciate the actions that I have to perform to get to alter/input settings. It would save me fiddling around using trial and error.

OAT is required for winds. The wind calculation is so sensitive to all the measurements that we won't display the winds unless we can get the OAT automatically.

Thanks for the reply. Apparently my D10 needs the external mag facility to connect an auto OAT and I do not have one fitted.
Apart from going down that line is there any other way of getting the OAT automatically?
Is there any way to get the AvMap to display a wind? It does have a wind feature, or should I ask this question on a AvMay forum?

You will need the EDC-D10A remote magnetometer in order to get OAT on your EFIS-D10A.

And on the EKP IV, you can only calculate the winds and get 2 numbers. You will not be able to get it displayed on the moving map.

Having an EDC and an OAT will allow you to get the winds nicely displayed on the D10A.

I have a similar setup with an EKP IV and it works pretty well.

I can see that I need the EDC. The wiring loom is there for it but I do not want to pull the aircraft apart to fit it at this stage.
Can I place the remote magnetometer, say behind the seat, but not turn it on? I could then mount the OAT sensor and have that part work.
Later I would then mount the magnetometer in its rightful place and have it take over the direction duty.
Sods Law says no - what do the experts say.

Thanks Jacques. Do you have a PCAS on the BUS?

I don't have a PCAS but when I read the documentation of the Zaon XRX that I found on internet, you will need to connect:
- the output of your PCAS (TD) to the EKP (RXA) to receive PCAS information on the EKP
- the output of your EKP (TXA) to the input of the Dynon (Serial 1 RX) to receive NMEA information on the Dynon
- all the devices on a common ground

I know that it can be connected and, in fact, I have it connected. I tried  to get it to work when I first installed the PCAS. I followed all the instructions and the result after some experimentation was that it stopped the auto pilot working because it put corrupt data on the BUS (according to a Dynon Tech who looked at the BUS data). I turned off the PCAS output and have had no trouble since.
I thought if you had one and had it working I could try your settings.
I guess that this subject should be discussed on the PCAS forum if there is one.
