Hi please, I need help to fix my andriod HU camera. I followed seller guidance to install and wire the device but it does not automatically switch on when I shift to reverse gear. And I had to install an andriod camera from playstore as I could not find any installed camera. When I manually open the camera in reverse, it work but the image starts from my left side instead of the center. The trajectory line appear from left to right. Can someone help? See pictures.

You need to connect pin G5 on the head units power connector to your reverse light power supply. This triggers the reverse camera to automatically display.
You should uninstall the Android camera app you have downloaded as it isn't needed.
These head units are vertical/portrait by default but have been modified to rotate everything by 90° to operate in horizontal/landscape mode. That's probably why your 3rd party camera app is sideways.
You should be able to view the reverse camera in 1 of the preinstalled apps. Try the app called "AV" or something similar.
Thank you for your response. I apprciate this. But I think I have connected the wires already as you advised. I had one PINK wire labelled BACK and one BROWN wire extending from the power. I connected these two wires to a RED wire extending from the Camera input. So, when I put gear on Reverse and manually open camera, it works but the image is inverted. I have uninstalled the playstore camera but the reverse gear does not trigger the (invisible) in-built camera.
The only pre-installed APP I have that could use a camera is TV. Also I do not have a canbus hency why I joined all wires together. I have also tried using just one wire, the same result. Is there a way I can rotate the camera orientation? I have been frustrated with setting this up. I have tried updating the MCU but no luck with the camera.

Is unit an FYT type? Post Android system information including MCU version
If you have a multimeter check that the wire you connected to pin 5 has 12v when you engage reverse. If it doesn't then it is wired incorrectly.
Yes it does have 12V. I'm thinking it has something to do with the software. Maybe there is no preinstalled camera that is programmed to appear when in reverse and also to remain vertically orientated. I think youbare right that these HUs are setup to open every single apps in horizontal mode and that includes third party camera. Question: Do headunits come with their own camera app? Mine did not come with a default camera software.

Hi all
Bought an RCA front camera as I was hoping I could use the f-cam app to get front and rear camera views and to get the front camera on for 10 seconds after reverse as per the option for the front camera in the factory settings.
So had a pig of an afternoon running the cables and what not but the only way I get the front cam view on display is by the AVIn app which isn’t ideal as it kills the radio and also seems to stall and affect the head unit.
Selecting front in the fcam app shows a warning of missing input and if you set it to activate after reverse the same occurs.
It’s strange for the unit that have the option of this function without actually doing it via the video in feed, Do I need another harness for this specifically for cam input??.
Here is the back of my unit. Can’t do the soldering to the board mod, but hoping there’s an easier way considering it’s part of the operating system.

Hi, only for dvr, I have that and it’s working well. But it doesn’t work with F-cam
Also noticed today that the rear f cam app is reversed ie left is right, but when reversing the view is correct. Can’t find any settings for the f-cam app.

Did you connected power to the RCA front camera? I do have a switch on my car to give/cut power to front camera itself.
If I don't power it up I get warning sign as well.
Hello! did you solve this problem? Im having the same issue
I have been spending the last week or two reading nearly everything in these android head unit forums. I have but one suggestion I cannot seem to find anyone who has tried it. I will be testing this method out shortly my self. But have you considered a 4 way video splitter. I have no experience with fcam app btw. Also I would mention that I have spent most of my time trying to find threads or posts of people who have used factory front/rear , 360 cameras for parking assistance. So far most seem to only use back up cameras or front camera for DVR(dashcam). American market brands of these types of splitters are 100-300$ usd aliexpress chinacom versions are 20-50$ I will be buying a china version when I get ready to order parts.
Was a solution ever found to this problem?
I am in same situation.
I have "fcam" app but it only shows reverse picture, can't workout which pins are for front camera so running front camera through AVin ....like above this is not ideal
Did you ever figure this out? Currently dealing with the same scenario.
I sorted it by buying a different head unit.. I now have a brosmartek 8227L and front camera works as it has its own input connection. It holds front camera image for 3, 5 or 8 seconds after forward gear is engaged after reverse
Hi to all,
I have the same problem and I found the solution..
So I found this diagram into the forum (https://forum.xda-developers.com/android-auto/android-head-units/vw-head-unit-android-10-t4132083)
As you can see there is an input for f-cam (No9) but if you see the plug (radio cable) the specific pin have no cable.
You must connect a cable for video with a new cable connected to pin No9 and you must also take the cround from another connection (I took it from No40) and with this two new cables you can creat a new female RCA for the F-Cam..
I hope my solution to help you...

hello, i am now attempting to do the same , what plug did you use on 9 ? and the one for 40 ground you just took it from slot 40 but where does it go on 9?
I just chatted with Eonon and they told me that none of their units show the backup camera while it's booting... That's a blow considering all of my vehicles have android headunits and this seems to be the only brand that doesn't have this as an option. I don't have my MCU and ROM info handy but, has there been any discussion about ways to show a backup camera during boot on units that don't have it working out of the box? Unfortunately there are no other sellers who have the "flat face" head unit for my Range Rover, so I'm at the mercy of the unit I have installed.
Thanks.
EDIT: It's an Eonon GA8201A if that makes a difference.
What's wrong with it showing the reverse camera upon reverse? While booting seems odd, especially when the OS is having to load.
Nothing else works while its booting so i wouldnt expect the camera to be any different, what model range rover do you have ?
I just fitted an Eonon GA2175 to my D3/LR3 but yet to route the camera cabling.

I has nothing to do with the OS loading and so on. It is normally activated by the reverse gear. Than it gets an electrical signal and the camera video is simply going over everything else. No OS interference at all.
So it could display on start if you have the gear in reverse.
If you do not have the gear in reverse it will not show. I don't know any unit that does this when not in reverse: OS loaded or not. Because it is not controlled by the OS, but by the electrical signal when in reverse.
This is from a central electrical signal: If it would function it would also mean that upon starting, whith the car not in reverse, also the reverse backlights would be on. That would be confusing and thereby dangerous.
Does your webcam work while the PC booting ? , no because the os still has to load before any peripherals will work which is no different to the head unit regardless if you select reverse or not.
My head unit displays the reversing signal through the OS. The Android firmware automatically switches depending on the reverse line. The only way I could see this working the way you say is by using the output of the head unit to the display + the reverse camera and then using a relay to switch between them. Completely separating the OS from the camera feed.
Its wrong design from eonon if this is the case.
The rear signal in all other px5 or a3 or a8 units is controlled by the mcu so when you switch the key and you put reverse no matter what the addon android card does it switches to rear camera.
I dont believe they had done that and you must wait the android to boot ...
Hi,
I have a Dicola Unit, and I have to disable the reverse camera warning, because I haven't installed the reverse camera.
Everytime in Reverse, it shows warning and I want to disable it.
Thanks
cut/disconnect the backup wire until you hook up a camera. Maybe your unit has an option to not use backup switch, but if not then your probably cutting wires.
In android 9, there was an option "Prohibit Reverse", something like that. In android 10, can't see that option.
Could you post a image of that option and the wire I need to cut?
Thanks for attention so
Sorry no idea what you wiring looks like
Hi All
I bought a Kunfine head Unit and a aftermarket reverse camera. I hooked up the reverse camera to the reverse light and ran the cable to my Kunfine android 10 head-unit. My Head-unit does not have a dedicated reverse camera Socket for my RCA cable coming from the reverse camera. So I plugged it in to the CCVB and i got an Image, but i have to select AUX on my head unit to see the image from my reverse camera. The unit also dont have a dedicated wire to fit to the reverse trigger wire. Can anyone tell me what i must do in order for the reverse image to come up on my android unit as soon as i put my car into reverse. There are no "back" or "reverse" wires on my head-unit canbus... Please help. I will really appreciate it.
Thanks

Hi There,
I have installed a generic android 10.1 - 2GB (RAM)+32GB (ROM) unit and have an issue with the reverse camera.
When in reverse, screen blanks out but no image.
I have had the unit and the camera replaced and have had 2 experienced installers look at the problem but no fix.
Does anyone have any suggestions to fix the problem?
Also, do you think a 12V DC Kit Power Relay Filter Rectifiers Capacitor may help?
Thanks in advance

The radio shows the blank black screen because the radio gets no video signal.
This can be related to 2 different things:
Missing 12V power at the camera.
Measure the cam connection for ground and +12V if your reverse gear is activated.
If there is missing something, you need to follow the cable and check the connections.
The fact that the black screen is shown, tells us that the radio itself is connected correctly.
Wrong CAM-In port used.
Check if you really used the CAM-In and not the Video-In connector
The capacitor is normally not helpful if you don´t get a video signal.
You don´t tell us in your posting how the power is provided to the cam. So that may help for further investigation.

The power to the cam is provided by connecting the positives from the camera to the reverse light positive input and the negative earthed. This is then connected to the android head unit, video input and the reverse cable.

Did you check that the Cam is connected to the CAM-IN connector at the unit?
...and did you measure the voltage delivered to the cam?
Which car are you driving? Does it have LED back lights?
Does the cam deliver a picture if you connect it directly to +12V instead of using the back light?
Without measuring, there is no need to answer from your side. This is mandatory to step forward.
i have the same issue. reverse camera show during installation but after few hours no image. only can see the lines. i connect the rca to my tv.it show reverse image .
I already wrote it in another topic. You need to use search instead of a new topic.. I don't know which car and which head unit. I had a VW Golf 6 powered by the reversing light and there was interference, stripes across the image. There are suppressors for powering from the reversing light, also on AliExpress. But the better option is mine. I found a pin on my main unit directly for powering the backup camera, which has 12v when I put it in reverse. It works perfectly, without interference or problems. I have a Can-Bus system. I'll put the pin-out of my unit here. Maybe it will help you.
And what about the black image after putting it in reverse, either there is no 12v power supply for the camera, or the input for the camera is incorrect.. use the cinch Reverse Cam input, do not plug into the cinch Cam-in this it is used for the front camera. Another option is to set the main unit for the backup camera, maybe the system is NTSC and it is set to PAL, or vice versa, depending on where you come from. Another option is to set the input of the backup camera type AHD, and the camera is normal, SD, I I tried the AHD type (better quality) and the picture was black. Inform us.
I got some issued on my android car head unit. No video input, on reserse.
Usinf canbus cable pink for electricity.
