Question Teyes CC3 reverse camera help!
- Thread starter Stephen2898

Hi, thank for you all.
My car is Mitsubishi Xpander, I did not know my car has Canbus or not.
But in my case, the head unit is Teyes CC3, and the rear camera was connected by Red wire to the G5 of the unit, and the Yellow wire did not connect anything. But my rear camera WORKS well when gearbox at reverse.
So my concern is:
- My car has Canbus or not?
- Why the Red wire connected to G5, and the camera works well?
- What is the function of Red wire in my case?
- In the unit has the Application CAR Recording, as I understand when we open that app, we can see the Reverse stage at anytime, Because the camera always powered, but it does not work. How can I use this app?

No that's not how it works. G5 is the reverse detection wire.
The camera should not always be powered. It should be connected to the reverse light and receives 12v only when you engage reverse.
It would not be possible to see the reverse camera at all times without connecting G5 to a permanent 12v supply. This will impact the reverse view showing when you engage reverse.
Some canbus boxes drop the voltage down to 6v for cameras that only require 6v.
12v might fry such a camera.
Thank you.
That is just my guess, I think it's wrong.
Anyway, Can I connect Yellow wire to G5 and Red wire to G3 as the instruction?
And in my case now, I curious why the camera can WORK when RED wire connect G5 and YELLOW was left alone.

By the way, is that masking tape what you are using? G5?
G5 ONLY activates when reverse is engaged, and G3 is a permanent 12v (maybe for the always showing the reverse CAM while driving). Is it right?
Hi, thank so much!
Yes, the masking tap is the connection between the Red wire and G5.
In the instruction, the Red wire must connect to G3 ACC; and the Yellow wire must connect to G5.
Compared with my case, the Red wire connected to G5, and the Yellow was left alone. With this, the camera is just shown when in gear reverse, and nothing when the car running and opening the App on the Unit.
1. What is the different between mine and the instruction?
2. And what should I do to see the image during the car running?
I just dont get it, why cant you just connect it the way it's in the diagram?
G3 ACC is for the image while the car is running.
Give it a try, (but dont forget to keep your G5 connected)

Hi!
It was done by the previous car owner, so I can not understand at all.
You mean now I should try Red wire to G5 and Yellow to G3, right?
How about in your case? Is it the same as the diagram?
Yes. my radio is a CC3, and that's how the diagram is intented to be set.
Try it and let us know.
Hey guys quick question.
Can you exit out of the reverse camera screen when in Reverse Gear and open an AUX camera screen? I'd like to put a rear camera on the caravan. But need to know that when I'm reversing I can switch to a different camera and not get stuck on the reverse camera on car.
Can anyone please confirm this for me?
Also just another quick one.. how many cameras can we connect to a CC3 2k?
Is it 4?
Reverse Camera
DVR (Dash Camera)
Aux 1
Aux 2
Cheers

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(?) )
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 hdmi1In summary, the rear camera needs power when you want to use it and the head unit needs a signal (i.e. 12V) to determine when to switch the display to the rear camera.
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.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.1So, you got the canbus module. Are you sure you need the canbus module? What do you need it for? Usually, the following are some of the functions that canbus can provide for the purposes of a head unit:
- dynamic parking lines when in rearview on the screen
- as you don't have a factory rear camera, you don't have dynamic rear parking guides
- reverse engaged status
- with no factory rear camera, this status is obtained from backup lamps as described in diagram/instructions
- I believe some even have video through canbus
- no factory rear camera so the video comes through the new wire you must install
- radar from rear sensors
- do you have these? If so, do you absolutely need them on the head unit?
- steering wheel control buttons
- do you have steering wheel control buttons?
- If you don't have these buttons, you can purchase a separate control with buttons and wiring and connect it directly to your new head unit such as this one:
- https://www.amazon.ca/Joying-Universal-Steering-Control-Android/dp/B08R6VK9PN
- there are several styles of these available but they all essentially provide several buttons available to you where the modules connect to key1 and key2
- If you do have these buttons, you'll need to find out where the wires for the buttons are or if the steering wheel control information comes through the canbus. If you can't find out about the canbus info but know where the wires are, you can try to connect the wires to the key1/key2 wires on the head unit. If you don't know where the wires are...you can always purchase a separate steering wheel control module as if you did not have any steering wheel controls
- controlling automatic climate control
- is yours automatic or manual?
- this does not normally matter. As long as you can set the climate controls without the need for the head unit, then you can live without having this info go through canbus.
- my car has an automatic climate control with it's own buttons and settings. it did not go through a screen for any of its settings.
As your car did not have a factory rear view camera, it most likely means you have to put in the wire from the new rear camera you install to the head unit. If you don't need the canbus, you'll have to wire the yellow wire as described in the instructions. If you need the canbus, then you don't wire the yellow wire as also indicated in the diagram/instructions.1A nice easy way to connect the reverse camera is to use splicing connectors like this FOCCTS 12Pcs Wire Connectors 2 Pin Low Voltage Electrical T Tap Quick Splice Wire Connectors Solderless Without Stripping Suitable for 20-22 AWG Electrical Wire Connection https://amzn.eu/d/9g7hX6r - Power is provided to the rear camera whenever there is power on ACC...which means all the time the radio is on:
