Question Teyes CC3 reverse camera help! - FYT Android Head Units
Hey guys
My first post on here so I’m hoping someone can help
Received the Teyes CC3 in the post today for my Astra GTC I’m not sure where to connect the power wire to the back of the radio for the reverse camera
There isn’t any loose wires on the loom for the power and the instructions just say to connect it to G3 ACC which I’ve attached a photo of but it isn’t clear of what to do
Any help would be appreciated
In 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
This is assuming you use the connection wire provided by TEyes that includes the extra yellow and red wires on both ends in addition to the yellow RCA jack that provides the video from the rear camera to the head unit.
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.
Hello, I appreciate your deatailed answer mastrv I also have a question with that topic. I attached diagram that shows connections on Teyes CC2 Plus.
There is a Note at top: "Connection on the yellow line will not be needed if you already have a canbus box and the reverse control line (G5 area) has been connected to the canbus box."
I have ordered a set for Chevrolet Cruze from AliExpress. I received a Raise canbus box (RZC as at the picture) in the set and according to the diagram and note, I do not have to connect the yellow wires.
Maybe it is about only the yellow wire on the head unit side but on the camera site I have to connect to Reverse Light Power Supply?
Please tell me how it should be.
What 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.
Thanks for your answer, my car is Chevrolet Cruze (year: 2009), it neved had build in camera or any camera. Unfortuantelly I don't have wiring schematics but I try to do things as on video tutorial created by Teyes:
I'm just not sure about the reversing mode.
So, 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.
You should try to get the schematics. Try looking around on through Google. Never know what you can find. The schematics can answer some of the above questions if you don't know.
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.
@gabol8000 I just had a quick look at the Cruze install link you posted. It did not use a canbus module and they connected the wire to the backup lights for G5.
Well I will use canbus box bacause I want my steering wheel buttons to work. So in that case you think I don't have to connect to 12V Reverse Light Power Supply?
If you are using a canbus module, the instructions say not to connect it...correct?
So, don't connect it and see what happens. Nothings going to break. At worst, there will be no image. At best, you'll be finished.
Then...if no image, it probably means your canbus doesn't have that info. Connect the wires and the image should appear.
I will do so I found a second video (newer) where the installation process is slightly different: there is no connection to reverse light and canbus box is used.
Here is full diagram of connections in my device:
https://cc2p.teyes.ru/en/map.html
The connection diagram is pretty much the same for the SPro, CC2 and the CC3 with maybe some minor variations. In any case, the question is what information does your canbus provide to the head unit.
Let us know what happens.
I have installed the device and everything works fine but with some minor issues with 1 or 2 applications but it is thing for another subject.
I did not connected the yellow wire on both sides there is no need to do it - the canbus is providing informations about reversing. Camera works great.
The only little problematic thing was that I had to strip the insulation from the G3 ACC wire so I could connect it with camera ACC wire.
Yeah, i dont really understand the difference between yellow cable + red cable and only red cable combos on camera video cable either.
When you have a video cable with both red and yellow additional cables, then camera gets the power from teyes device (red cable from camera power cable connects to red cable from video cable, and near teyes device, red cable from video cable connects to a loose power cable (number 3 on scheme) that comes from teyes power cable bundle), and yellow cable acts as rear gear detection switch - yellow cable near camera connects to rear driving lamp cable of a car, and the yellow cable near teyes device connects to a loose cable (number 5 on scheme) that comes from teyes power cable bundle. Then when you turn on rear gear, teyes gets signal from rear driving lamp, turns itself into special mode for camera only, and sends power to the camera. This method works, i have done it.
But when camera has a video cable with only red additional wires coming from it, then i dont get it - do you need to connect camera power cable to a car cable that always has power, or to a rear driving lamp power, and then connect red cable as a trigger wire ? Is there a difference of camera getting the power from car directly, or from teyes device ? Why there are 2 variants of rear camera video cables ?

The yellow cable is the TRIGGER signal from the reverse light to the head unit, which tells the head unit to change its input from what ever it is presently on, to it reverse input. The red cable is POWER (12 volts) going to the cam so it can power up. (If you have CAN BUS and a can bus adapter, then the yellow in most cases doesn't need to be connected. The can bus will deliver the reverse signal).
It doesn't really make a difference where your cam gets its power from (the red wire), just so long as you are feeding it 12 volts any time you wish to use the cam. It's just more convenient getting it from a dedicated connector on the head unit.

Ok, but how about all the cars that dont have CAN BUS - there are plenty of rear cameras for those cars that have video cable without yellow wire, only red one. Do you have to use red wire as trigger wire, and give camera power directly from the car (power from always on source, or from rear driving lamp) ?

I have a video cable with only a red cable... no yellow. I also have can bus so I didn't need the yellow, but if I didn't have can bus, I would have to run my own yellow wire.... either that or use the red one as the trigger wire and run another power wire from somewhere.
Just installed Teyes CC3 with video converter box in my Wrangler JL 2021, to use the factory reverse camera.
Had to try few ways to connect it, but when you take a moment, then realize it is simple to do.
If anyone has issues - let me know, I can share my experience.
P.S. I did confuse 2 factory connectors (rear cam and radio antenna - last one is the thicker one). Turned out the factory rear cam was the tiny one. Otherwise make sure to connect to separate yellow CAMER IN RCA plug, and do not cut pink wire on converter box.

Has anyone installed a 6V factory camera to the Teyes screen?

The camera voltage shouldn't matter to the head unit being used.... just don't connect the camera's power leads directly to the head unit or you may blow the cam. You will have to use DC to DC converter (or similar) to drop the voltage to power the cam.

Click to expand... Click to collapse If you want to take the case apart you could remove the power button and wire in a short throw solenoid that is activated by the car's internal 12 volt power. This would trigger the tablet's power button automatically when the car started. You'd need to root the device to install a power off button on the homescreen through so you could power it off via the touch screen.

Click to collapse thanks man, about root and install power off button i already done it, no problem, and i am working with "smart screen on" and "off ". about your suggestion, i am not sure if i am able to follow your idea with my poor knowledge. i will appreciate if you can give me a little step by step guide. eventually.... let's say that i dont want to remove the power button.......... if the device for some reasons will shut down (not just the screen, i mean total power off) is there a way via pc to power on again without use the power button? maybe adb command or other way? thanks again to all, i have almost finish all the work so that i am ready to assebly it on the car....... cheers
Well you can't use adb to power on the device. That deffinately doesn't work. What I was talking about was using a solenoid that runs on 12 volt power. Basicly a solenoid lets one electrical circuit influence another electrical circuit without the two circuits connecting. The car's DC power would activate the solenoid which is basicaly just an electromagnet. When it has power the electromagnet activates and a little piston inside it completes an electrical connection for the circuit you want to power. Learn more here Even easier to wire, you could also move the power button. Just take out the one that's in the tablet and run two wires from the existing leads to another power button that you remote mount somewhere else. This won't be automated to start when the car does, but it will let you use a remote mounted button that functions exactly like the existing power button. The only down side is the difficulting in installing those lead wires. The power button in the tablet is wired with a VERY TINY ribbon cable. It's basicly two copper lines embedded in a single flat plastic wire. It's very delicate work to cut those and soilder in new wires. It can be done, but it takes a delicate hand with surgical precision. If you do it right though, it will work like a bloody charm. And you can put a power button on your dashboard somewhere that's easily accessible. The 3rd option, that's the least high tech, is to fabricate something that lets you press the existing power button. Perhaps a hole in the dash bezzel that surrounds the tablet that lets you stick a finger in under it and hit the button. That's guarenteed to work. It just involves careful fabrication to make it look nice. Also, for the application you're trying to use the tablet for, read through this message board.... http://www.mp3car.com/vbulletin/ It's a message board dedicated to in car computers. I built a Windows 2000 based PC to run GPS and audio in my car and that forum was absolutely invaluable. If there's another sollution to remote mounting smartphone power buttons it will be there with how to guides. It's a great community for getting help doing the kind of project you are working on. They will probably have good software ideas for you too to get the best use out of the tablet for your purposes.

I have one in my dodge magnum. If your looking to have your tablet turn on with the ignition you can try a program called tasker. I have power supply attached to my ignition and when I turn on engine my tablet wakes up. I have a ton of things automatically start when it recieves power. Everything pauses when it doesnt recieve power. Or you could also try tablet talk and maybe those nfc sticker things. You have a lot of options of you dont want to open up the tab.

I second the Tasker solution. Also, since you're mounting in the car anyway, i would look at an app called Torque. A cheap bluetooth OBD2 interface can be used, and Torque can be set to put the device in standby when ignition is turned off or when tab isnt "plugged in" (because power to tab is switched by ignition). Using Tasker, you can wake the device when the ignition is on, then start the apps you use while driving (pandora, maps, nav, my tracks, etc). There's a bit of a learning curve with Tasker, but spend a bit of time with it, and you will start to see its potential!
Yes. Tasker is a great app. I use that in my og galaxy tab I have installed in my car. I wouldn't worry about powering the device on and off. If your trying to save power, you won't lose much even on really hot or cold days. Tasker has a lot of options that you can set to help save power.

[Q] Question! Permanent Car Dashboard Project.
Hello Gentelmen, I am rather new to android dev but seassoned in linux, i decided to convert my old phone (samsung admire) into an in dash computer. I am using two basic applications: * Torque OBD2 Connector: This connects to the car's OBD2 Port, reads the computer and displays information on screen (like HP, Torque, Manifold Pressure and temp, Boost ...... ) * Autoguard Blackbox: This app acts as a CCTV recorder taping my driving and saves it in case of accident so i can have video evidence. I have modified the andoid system to open both applications on boot and on external power and to kill them when external power has been disconected. Also when external power is disconected phone will wait 5 minutes then go to sleep. (yes i realize there are apps for that but i like shellscript) This means that when the key is turned and the car is on recording automatically begins and my gauges come up, when the car is off they close AND STOP RECORDING and go away without any kind of interaction on my part. The problem: Whenever the car turns back on, external power is connected and i would like to have the phone do a full boot so that my scripts kick in,however instead it goes into charge only mode where it boots in to some kind of "hybernation state" that only displays the battery charge in the middle of the screen. I would like to bypass this and have the phone do a full boot whenever the power is connected. I have searched for weeks and have found nothing but people withthe same problem and solutions that involve harware and wiring and soidering however this is not an option for me because the phoen is exposed (not actualy insidethe dashboard) I am not afraid to compile a custom rom and have it run on the phone ... the phoen is solely for the propose of having the dashboard display. (i dont use it for calling) Could you guys point me in the right direction? Thanks in advance.

"Sound enhancer not available over HDMI Connection"
So I bought a standard issue MHL cable for me One X and I hooked it up last night to an HDTV when I got home from work. Worked just fine, zero issues with it. Wake up this morning and I try the same thing, I just plug my phone is to the same connection set up I had going on last night and now my phone decides it doesn't want to output over MHL... You hook it up and red notification light comes on, so I know there's power coming through it at least, The screen goes landscape and for a split second I get an image on the HDTV and then message comes on the phone that says "Sound Enhancer not available over HDMI connection" and goes back to portrait. If I leave it plugged in, it will do this in a loop. I tried force closing and disabling Sound Enhancer app but no luck. Also tried different HDTV and no luck. I'd hate to think the cable's bad... Any other ideas? or anyone else with this issue? Running CleanROM 5.1
Problem Solved So After letting it go for a little bit, I decided to try hooking stuff up like I did the first time. Which was: plug HDMI MHL connector into TV, Mini-USB into phone, power-USB into TV. When I was doing this the second time around, I noticed that the image came on the screen from my phone no problem. I hadn't even plugged the power USB in yet. Simple fix, yes but it made me wonder because I had thought that the whole nature of the MHL HDMI connector was that it required an external power source (in this case the power-USB) in order to output the image. Though I guess through this little experiment, it seems its only optional if you want to charge your phone while outputting an image. After I got the image up on the screen, I tried to hook up the power-USB into it and as soon as I did that it started erroring out with the Sound Enhancer crap.
Some kernels now offer the ability to power it without needing an external power source.
TF101 does not display on screen (through hdmi output works fine)
Hi, my name is Josemari, from Spain. I have a TF101 with dock (and original rom from Asus) that does not display anything on screen since a soft fall from 10cm (daughter in a very very small chair). When i plug the charger, it works (and beeps -charge-). When i plug the dock, also beeps. When i connect through hdmi output to my tv, it also works. I can use the tablet perfectly with my fingers. What can i do? I disassembled the tablet and i checked all conectors, but i do not see anything wrong. Thanks.
I had the exact same problem. Even though it has fallen before without a problem, in my last 2 cases it was a loose connection for the video screen. I had to open up the tablet and simply push the video connection back on all the way. It's rather easy if you're familiar with taking things like this apart. Make sure you are careful when you re install the side trim that holds the buttons. It's easy to break the red tabs that press against the buttons. It may be helpful to you to look up a disassembly guide. I believe if you google the specific issue you will find pictures. Again it's been a long time. Hope this helps
I have the same issue since a few days. Difference here, when I boot up (holding power button until reboot) the screen is on (Asus logo and boot animation) The display goes balck / disappears (backlight off) when the lock screen comes up. Checked the inner display cable and connector with no success. Did a factory reset and it was working again, until I changed the brightness to a higher level. Then the screen was dark again. I managed to change brightness to a lower level using the working HDMI interface. After that I switched the tablet off and on and the screen was lit up again. Another effect: when power adapter is plugged in, I can go to a higher brightness level until the backlight turns itself off. It looks like a hardware defekt of the backlight electronic to me. Couldn't find any spare parts, such as backlight inverter, though. Can anybody confirm this or knows how to repair? I will use it at 30-50% brightness now and see if it gets worse over time.
PX5 Buttons illumination not working
Hi! Bought a car with PX 5 HU installed, but buttons illumination is not working. Tried updating MCU — didn’t helped (current version is MTCE KGL v3.10). Tried turning it on in factory settings, but illumination is not working even in “by power” mode (also tried RGB and single color — same result). Though screen brightness adjusts by head lights and is working perfectly. Any suggestions on fixing button illumination?
What voltage do you have on the illumination wire when the lights are on? What else have you checked apart from software?
marchnz said: What voltage do you have on the illumination wire when the lights are on? What else have you checked apart from software? Click to expand... Click to collapse 12 Volts. As I said screen brightness works, so HU understands when head lamps are turned on. An illumination doesn’t work even in “by power mode”, so I believe the problem is not in wiring. I also checked if diodes in buttons are not burned-out, but they are ok. So I reckon there are only two possible problems: software failure (may be previous owner updated MCU from another manufacturer — may be it was HA and he updated to KGL) or illumination is not wired on the motherboard.
Illumination doesn’t work even in Recovery Menu.
