Adding Pop Out Garmin 430 to Premium 172 Panel

[SteveOcean]

I'm flying the Airfoillabs 172SP and I would like to add the Garmin 430 to the panel. How do i make the black background transparent just behind the where the 430 is supposed to go? When I drag the Pop Out to the panel, it disappears behind the black background of the panel.

You have to put a transparent section in the background image. It’s all explained here.
