Peter,
If the Camera menu is NOT already on screen:
1.)Go to "flight settings" at the bottom of the screen.
2.) Open "Camera Select"
3.) Choose "C-GO3-Pro"
WHEN the drone/camera are bound, select the "gear" icon near the LOWER RIGHT of the main screen. That will give you options such as resolution.
You should not need to change any settings for the new SD card if you are happy with the current settings. You only need to change the settings if you want to use a higher resolution, different "image Style", etc.
