Head unit B9012 Wiring Diagram --> Looking for Camera wires

[Rwin]

Hi,

I own a 2010 Avensis. It came with a B9012 and rear view camera. I recently replaced the unit with aftermarket Android 8 (PX5 Chipset) head unit. Everything worked instantly but... i like to use the camera already in the car. Problem: i can't find the wires. I guess they should be in the 20 pin connector at position 1, 2, 11 and 12:

Unfortunately, i can't get it to work. When i put the car in reverse the new head unit switches to video input but no video signal 😞

Questions:
Does someone have the pinout for the 20 pin connector used with the B9012?
The Toyota camera, is this a 6V or 12V camera?
Something i'm missing?

Thought i had the solution but:

https://www.qualitymobilevideo.com/ax-toycam2.html (24PIN)

https://incartec.co.uk/category-listing/Reverse-camera-retention-adapters (16PIN)

Nothing in the middle 😞 

And found http://carsounds.nl/producten/camera-interface-toyota/acv-camera-adapter-toyota-diverse-modellen-2/

But with this one i will loose the other steering wheel controls (and ground)

Someone any idea?

Hi Erwin,

Did you manage to solve this issue? I'm facing the same problem. The unit switches to video but no signal. 

Thanks in advance
