The Android Headunit will have a yellow RCA Phono socket marked CAM_VIN, CAMERA IN, REV_CAM or CAM_IN

But what are these yellow connectors for and how do you wire them up?
Will the android head unit still work if CAMERA connector is not installed?
How do I connect the camera to CAM_VIN?

CAMERA_IN is the reversing camera input on a universal fitting android headunit. The CAM_VIN socket is a yellow connector that takes a male RCA type phono plug. These carry analogue video signals.
The CAM_VIN socket is used to carry the reversing (backup) camera signal to the android headunit screen.

Pink wire

CAMERA IN and the PINK wire are used together in an android headunit installation. You don’t use one, without the other. PINK wire switches the CAMERA input on and off. CAMERA carries the pictures from the reversing camera. By using the PINK wire and the CAMERA input your android headunit can show the backup camera when it is needed.

Omitting CAM_IN and PINK wire

Not installing the CAMERA_IN connection with its PINK wire counterpart is a loss of one of the main features of an android headunit. The reverse camera feature plays a major part in the justification in installing an android head unit. The headunit will still boot up and do everything it should. It just won’t display the backup camera when it was expected.

How to connect the CAMERA_IN cable?

CAM_IN is for the reversing camera, but not in isolation. The use of the PINK REV wire is also required for a successful CAM_IN feature. The Connecting a reversing camera to an Android Headunit article is here. It covers the installation of CAMERA IN and PINK REV wire for a working backup camera feature of your android head unit.

Yellow Socket

With the yellow socket being very popular on an android headunit wiring loom, it can be difficult to know which yellow socket is which. Sometimes the labels are missing, other times they are wrong. They are nearly always in Chinese. If you have one of the very popular 8227L based android headunits then your CAM IN connector is on the lead with the two short blue aerials.

If you don’t have this short lead with CAM VIN label, your CAMERA input may be on the rear panel or on a more populated loom. It won’t do any harm to the camera or to the android headunit if you need to trial and error the yellow RCA phono connectors. Try each of the yellow sockets with the camera plug until you find the right one, then label it for future reference.

Back Video In

You may also find the ‘CAM_V_IN’ – backup camera video input labelled ‘Back Video In’. This is a shortening of the name ‘Backup camera Video Input’. You connect the RCA plug from the reversing camera to the BACK VIDEO IN connector on your head unit.

Don’t forget

To attach the (probably oink) REVERSE wire on the android headunit to the reversing light circuit of the vehicle to enable the Video Input of the camera. This way the headunit can automatically switch to the backup camera when the reverse gear is selected. If you don’t connect the REVERSE wire to the correct circuit the camera can either be shown all the time or never.
