Install of Pioneer SPH-DA360DAB - Rear camera issue

Dear Prius owners, hello!

I own a Prius XW30 from 2009 since +10 years and I've decided to try to install a DAB+ and CarPlay device.

I knew the rear camera could be an issue, considering the blue connector, but I tried anyway.
I just installed this LVDS to CVBS adapter.



Patched the 3 cables to the wire harness of the Pioneer.
I concluded that the black cable is for ground, red for 12v and yellow for B+, permanent 12v.

Unfortunately on the Pioneer, when I open the camera menu, it shows "no video input"

Any idea how can I try to fix this ?

Here are the cables going to the original Toyota multimedia device.


Best regards
Ian
