The diagram shows that:- Power is provided to the rear camera whenever there is power on ACC...which means all the time the radio is on:
- On the head unit side, the red wire is connected to G3, ACC, to send the 12V to the rear.
- On the rear camera side, the red wire is connected to the red wire from the rear camera so that the camera receives the 12V and is powered.
- The 12V signal to the rear camera is provided to the head unit when there is power on the backup lights:
- On the rear camera side, the yellow wire is connected to the backup lights. Whenever you put your car in reverse and the backup lights get power, the 12V from the lights go to the head unit on this yellow wire.
- On the head unit side, the yellow wire goes to G5 which signals the head unit to display the video from the rear camera
Does the above make sense? Note that the diagram shows that the rear camera will always have power. I've seen comments that it's not a good thing to always have your camera powered as it may reduce the life of the camera.
Did your car already have a rear camera or are you adding a camera where none previously existed? If none existed, then you pretty much have to use the wire provided. If your car already had a backup camera, then other issues come up. Also, your car probably already has wiring going from the rear to your old head unit and you could use that.
Remember, this is only advice and you should confirm any of the information given to you. You take full responsibility for anything that you do...
FYI, I don't have a CC3. I have an older SPro / CC2 but the wiring for the rear camera is the exact same.2
Well... to be fair, it should be mentioned that ANY camera using RCA will appear at a lower resolution. RCA only supports standard definition (if I remember correctly, that is a max of 720x480(?) )Disadvantage:
1) If OEM camera is low resolution, the image could appear bad on the larger screen.
Those cams which are advertising "1080P" and then show an rca connection in the pictures... well.... maybe the cam itself is a 1080p cam, but the head unit sure isn't seeing that.
For higher definitions, you need usb or hdmi2
Not necessarily.Don’t think you shall connect any power at the unit. Camera gets its power at the back of the car, from revers lights if I remember correctly.
If you want the cam to work all the time then you need to connect to a power source which is on all the time. With the cam powered by the reverse light you will only be able to use that cam in reverse and not as a monitor while forward driving (a great many headunits come with the ability to use the reverse cam as a monitor)1What year is your car? Does your car already have a rear view camera? If so, does your car have any wiring specifically going from the rear camera to the front / old head unit? Here's a portion of the schematic for my car. It shows specific wiring in the harness to the (old) head unit. I used this to connect to G5 to trigger the new head unit to know to display the video from the rear camera:
You should know the wiring schematics for your car. Information is sent through canbus. Different car makes and models provide different information through the canbus. Depending on your car, it may also send the reverse status for your car. My car is a 2012 and the reverse information does not go through canbus. I run my head unit without a canbus module. Not sure if you can override this and have your head unit ignore this information or if you need to.
I'd say to try without connecting that wire and if that doesn't work, then hook it up as needed...unless you know for sure the information that goes through the canbus.
NOTE: My original rear camera built-in rear camera runs at 6.5V so I also had to adjust the voltage to 8.6V or a little over that so that the head unit recognized it. I believe the Android head units need at least that to trigger displaying the video on the screen. Yours may be different so you should verify that. However, if you use a camera your purchased or that was provided by the vendor, it probably runs at 12V so you should not have to make any changes to voltage. Again, you should verify this. I did testing on the kitchen table before installing the head unit. I also did voltage measurements with a multi-meter on the old head unit wiring to verify voltages, etc.
As always, this is only advice and you are responsible for anything you do. If you're not comfortable doing this, have someone else install or wire up the head unit that knows how.1 - Power is provided to the rear camera whenever there is power on ACC...which means all the time the radio is on:
