hi all have a toyota chr 2017 uk
have and andorid unit qt10/ts10 - all wokring fine on canbus
except rear camera - want to use orignal
the seller has said that it will just work but i have seen that some cameras are 6v/12v
do you think the head dunit will output the right voltage- or the voltage is coming from elsewhere anyway and i dont need to worry?

also all that remains is that i connect the reverse (back) cable form canbus to black cable in harness (12v) i think?

thanks
getting desperate here

I have canbus hy-ss-04
OEM camera with 2 wires, black and red
I connected the red cable to g5 reverse detection
When I put it in reverse the camera works, but the problem is that it also works all the time
It's a great thing, the problem is that I don't think my camera will survive because it's always on,
How does the function that always shows the reverse work if the multimedia receives g5 reverse detdetection and not ACC G3 voltage...??
Does the camera only turn on when I turn on this mode? If I am on teyes vision, and there is no display, it does not turn on

hi all
i received a oem retention cable for camera
fitted and wires positive wire to "back"cable coming from canbus adaptor.

if i use the FCAM app and put it in reverse i can now see the camera!!!

but putting in reverse doesnt shift the head unit into reverse mode
any ideas please?

The back cable from Canbus goes to headunit, if you want to trigger the headunit you must connect the positive to the cable goes to headunit and not to canbus

Sorry positive of camera goes to head unit cable, but which?
I don’t know what your conn is right now. The headunit has 2 cams inputs one for front camera and one for the reverse camera. You must connect to the reverse camera input. Then if all is working ok (including the Canbus box) you should see the camera when you put the reverse. If not and you know the camera is working then the Canbus box is not working properly, in that situation you must connect the positive from the reverse light to the back cable of the headunit, usually the back cable from the headunit goes to Canbus box.

hi Leo06
hi - the back cable is FROM the canbus box and loose - so i attached that to the camera positive
and can get image like i said .

you are suggesting that the canbus isnt working correctly then - i will take another look

i know the "back" cable is around 12v so that why i used this - and only supplys 12v when car is in reverse

Did you connect the reverse camera rca cable to the correct input of the headunit? The fcam is for front camera not the reverase. The normal camera have 2 cables one for power and one for video signal (yellow rca) with the rca cable maybe there is one more red cable, that is for triggering the headunit to the reverse input. If the Canbus working properly you don’t need that red cable, the headunit must go to the reverse input through Canbus signal.

Yes connected to right cable, I used fcam and another connector just to test that it was working.
As this pic shows
Retention cable rca to back of head unit.
6v adaptor red to back cable
And loose black cable from 6v adaptor.
So like this I get nothing from camera, And it doesn't switch to app for camera

A 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

    What does seller suggest when contacted for support. What has been tried, adjusted. What does installer say
    They (local installer) said this issues has not been fix yet, other cars they installed to connecting the OEM reverse camera all had the same image interference effect (or even worse than my car) (?!)
    We also tried using some 12V power line noise reduction filters (sample as attached photo) but still didn't work.

    I need to help if anyone has an idea about this issues.
    You have set the camera type to CVBS in the options.

    Disadvantage:
    1) If OEM camera is low resolution, the image could appear bad on the larger screen.
    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 hdmi

    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.

    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:

    1627473906586.png


    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.

    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:
      • 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.
