I have recently purchased an OEM Android Auto unit from China for my ML 350 W166 2013. On connecting it everything works well except the reverse camera video. I have the original MB camera still connected. It powers up and shows the reverse guide lines but there is no pic when i engage reverse. The vendor says i must buy a camera from him to have that function but i think there's one more step to make the reverse camera work since it's already powered without changing or drilling holes to add an OEM camera. Just need the video signal to show.


Any help or suggested wiring to complete the setup


Hey mate


Was the unit you purchased from China branded or with some kind of warranty? I've had a couple of my friends go through similar experiences.


I think, the vendor is correct in this case to be honest. They are up selling but that is the way they make money. You might not get a video signal since there is no output at all.


My recommendation is to not play around with your current unit and buy the camera from the vendor. It should work.

I bought the unit in China. I guess i have to order the camera from the vendor. Thought i could find a solution on here

I would check under setting to see if there anything that will allow you to configure the video input.

Also did the unit you installed have a seprate input for video? Check the owners manual it should something something.

The other isssue here may be the head unit is not turning on the camera because it is not realizing the car is in Reverse gear.

Let us know what else you find out.
