Support for the DJI 04 air unit/pro and Googles 3 with Ardupilot.

This is my attempt to put all the info that I read into one location.

Here are some links that are helpful with the setup…

This setting is not inside the googles 03 found at this and many other links so you can’t change this…

At this link I talk about having issues with the osd not covering the whole screen. The fix was clicking “HD layout” under the config tab then osd menu in MP, make sure you only drag the osd icons within the 50x18 screen size otherwise it will fall out of the googles screen.

So all in all it was a really easy setup, all icons work for me and it’s really clean inside of the googles.

I am using speedybee f405 v4 flight controller,
I haven’t tried this on a cube or my holybro just yet but that is coming.

These setting worked exactly as in the screen shot.
If after all this and it still doesn’t work make sure you are using the correct serial port . If the serial port is correct and it still doesn’t work, some of the reading says to change to a different serial because of conflicts. Try that.
