Rear view camera Citroen C4 Grand Picasso 2015

[GORAX]

Hello everyone,

After I have completely repaired my vehicle (Nox and Adblue problems) I would like to upgrade my car a bit.

I would like to install a rear view camera. I find various universal cameras on eBay and Aliexpress. Do I just have to connect it to the display with the video cable? I installed an Android Car module in my car because Android wasn't included as standard.

Does anyone have experience or perhaps instructions for me?
