Hoping someone can point me in the right direction on how to retrofit the factory installed OEM rear camera into an aftermarket Android apple carplay head unit?
The aftermarket head unit can take in a composite video signal. 2018 F55 Mini.

In looking at the factory main head unit connector it seems that pins 21, 23, and 24 are FBAS signal from the rear camera? Is the FBAS signal on the pins composite video?

I did try tapping into these pins and used a monitor but was unable to view any camera video.

Thanks for any help!
