Hello everyone, I have an audi a4 b6 from 2001. I bought a Chinese radio with addroid model D02022HA16_AHD_00012_V009_HIFz from XY AUTO for the car.
searches for this model on the Internet but there is no mention of such a radio anywhere. The problem is that I bought a rear view camera for it, connected it according to the instructions. I connected an additional can bus filter on the camera power supply to eliminate the interference.
After engaging the reverse gear, the camera turns on, but only the snowy image with stripes appears on the screen. Can anyone help me how to solve this problem. I'm sending pictures in attachment.
Regards.
Marcin.

Reverse camera no image.
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...

Hello guys,
I have a huge deal trying to implement the front camera on Joying JY-UL135.
I have allready the rear RCA camera installed, and it works great with the reverse gear.
I've connected the front camera on the AV-IN, and it works when I use SRC button on AV-IN, but I want it to work as a front camera, so I've activated it in "Factory Settings Menu", but it shows me a yellow ! sign, and no way to make it work.
I've asked Joying, but no good answer. :crying:
Is it possible to make it work somehow? Maybe by flashing with a compatible MCU? which will handle it as Front Camera and not AV-IN?
Thank you,
Cheers,
Front Cam
Did you power the front camera beside's using the RCA.
Damit17, not yet.. this is what i was thinking about... but from 4pda forum, it seems that F-CAM RCA and AV-IN are differnt.
Is it same input? did you tried it?

Thanks marchnz.
My problem is, Joying does not support officially front cam. The unit has only AV-IN.
Would this be because Joying expect the front camera to be a USB camera/DVR as listed in the wiring diagram? The AV input wasnt intended for front camera operation; this is for DVD players, DVB-T TV tuners etc.
Unless there is a way to assign the AV input via [Factory Settings Menu]?

Hi, maybe something like this may help - Car Parking Camera Video 2 Channel Converter Auto Switch Front /Side/Rearview Rear View Camera Video Control Box with Manual
I have no experience with this unit but tempted to look into a solution like this.
did you ever get this to work?
F-CAM app does not work for me either for rear cam... It shows yellow ! sign... I have a Seicane PX3 android head unit.

My mtcd unit has a front camera RCA input and an F-CAM power connector. F-CAM app and front camera work out of box with this unit.
If you don't have these connectors and are interested in getting F-CAM to work, follow this thread:

Okay so Im trying to get my Eonon Andoid head unit for my E46 BMW to switch to Reverse Camera when I put it in reverse. I have wired the camera up for power from my reverse lights and ran RCA to the front and connected it to the head unit. This worked fine when my car had an Auto transmission but after I swapped my car to a manual transmission the camera will not auto launch on reverse. It does work as I downloaded an app to open camera and when I put it in reverse the camera shows whats behind me. But if I'm not manually opening the camera app the head unit does not switch. Any ideas?
Eonon may have mislabel the RCA lead, did you try the other video in leads? It should have come on when the camera got power from the reverse positive lead. May also be a firmware issue. Contact Eonon on Facebook and describe it to them. They may send you a firmware update.
I'd like to hear from anyone who has got a PX6 in their Transporter T5.1.
I bought an "SWC" / "Erisin" PX6 4GB/32GB Android 9 HU to replace my PX5. Fitted it and discovered it was not MTCD/MTCE.
I could not get my reversing camera to work with it*. All I got was a flashing "No video signal" message. I sent the HU back for a refund.
Would still like to get a PX6 but need the reversing camera to work. Would prefer MTCD/MTCE. Anybody on the forum done this?
My van is a 2014 BlueMotion 84kW TDI model. I believe 2014 models are a bit "special" electrically. I'm just trying to gather information about PX6 HUs that might work in my van.
(*Longer version: Tried triggering the HU Reversing function with: just CANBUS; with direct connection to reverse light +ve; with connection to +12v via a relay; and connection to battery +ve. (These last 3 by cutting into the wiring bundle as suggested by Chinese technician) but nothing worked. The (rear facing) camera worked perfectly when plugged into the HU's RCA DVR connector and camera now still works with my re-fitted PX5)
Hi there,
Did you make it work eventually?
Here is my experience with a PX6 on my T5 (2009) - will copy paste a post which I already wrote in another thread:
I recently noticed my PX6 unit doesn't see any of the front / rear cameras. With all wires connected the f-cam app shows the orange triangle (no signal) for both front and back cameras. The same happens if I give a 12v signal to the reverse (pink) wire.
I never got to install the backup camera in my car but I did bench tests with a power source and had the cameras working when I first got the unit. Now, a few months later, the cameras simply don't work
I tested with 2 different cameras and also with a DVD player and none worked.
I even opened the unit and checked the motherboard to see if there is a fried circuit or IC...and saw nothing. The video inputs lead to a IC labeled "FMS6502" and the signal gets to it through a 75ohm resistor and a capacitor which both look okay.
What can it be?
So these being said, I am afraid these units have some hardware issue with the front/rear camera inputs.
PS: on my Opel Combo car I have a PX3 unit with working rear camera !

My reversing camera worked if plugged into the f-cam input, but of course this is useless as you need it to be triggered by going into reverse and f-cam input is not. Atleast it meant I could be sure nothing was wrong with my camera.

I think my PX6 was expecting something special in the trigger signal. 12v DC from the reverse light did not work. Nor did 12v DC straight from the battery via a relay. The PX6 wiring loom lets you choose between CANBUS and non-CANBUS configuration. Neither of these worked. I even hacked the wiring on instructions from Erisin in China with no success (They clearly misunderstood their own wiring diagram though, so I never expected the hacking to work).
So these being said, I am afraid these units have some hardware issue with the front/rear camera inputs.

I think you are right. There is a hardware issue. I have a PX5 which works fine with the reversing camera input but the trigger signal has to be 12v DC direct from the battery via a relay triggered by the reversing light.
It was a shame because the PX6 was faster than my PX5 and the screen was brighter. But not having a reversing camera was a showstopper.
Thanks for you reply!
Regarding activation of the reverse screen, I managed to make good use of the canbus decoder box which they sent me from China (first one didnt work, them they sent me another one which recognizes the CAN messages correctly).
So the problem is that the unit doesn't receive the video signal from the camera, although it gets into reverse mode.
Moreover, the unit doesn't show the camera image by using F-Cam app either...hence I believe it is the video controller (FMS6502) that is faulty. I have to check it with a multimeter based on the specs of it...
These units are atractive but they have serious flaws in their mechanical (cheap plastics, buttons, etc) and electronic design.
Sending the unit to warranty in China is a lost cause too...

Yes, it sounds like you have a hardware fault. For me it was some sort of incompatibility in the camera signal/reverse trigger.

My Erisin branded PX6 was very poor quality compared to my Xtrons branded PX5. The connectors and the buttons on the PX6 were very fragile.
I was lucky: the UK importer refunded my money, but only after I told them I would raise a dispute on EBay.
Hi Everyone
Thanks in advance for any help you can offer.
I have the following head unit
YT9213A_00009_V001_20191203
Android OS:9.1 (8.1 go) XY Auto:3.1 (8227L)
Can Pro: 3.0 (8227L)
DDR: 1G Flash: 16G
CPU: A7 1.3 Ghz x4
Display : 1024 x 600
MCU:3.1 (8227L)
A few issues since install :
1. No fader controls - major drag
2. Rear view camera does not display and loops until the car is taken out of reverse. Seems the head unit cannot take anymore.
This is one of those cameras that has a combined power / signal connector (polzoe connector - I think)
I have also added a DAB+ Aerial on USB - works great (thanks Zoulou is it).
I did not complete the installation of the rear view camera as it would have meant butchering my rear
bumper for something that possibly does not work.
I have run the cable and would really like it to work. Not sure whether this is a head unit limitation or if is should pursue with the suppliers of the camera.
I'm leaning towards the headunit..
Hello I have the same cartablet as you and I have the same problem with the rear view camera .... I found a small solution .... I set the stereo that restarts at every switch on, that is when the nissan logo and the Android one come out, by magic rear camera works, but only and exclusively while loading the settings, once entered on Android the rear camera no longer works !!! Anyway, it's a ****ty tablet ....
I've searched for my particular scenario and I haven't exactly found it. I have a 10.1" android headunit sold by Rongji listed here:

I've wired my reverse camera into the back of the headunit for power and the AV cable is plugged in accordingly. When my vehicle is running and I go into Reverse, nothing happens.
However I can click on the F-Cam app and choose reverse camera and the image shows while in Reverse.
Is there any way to make this happen automatically?
I've not understand the comments I've read through where some say the reversing action is managed by the headunit software not by F-Cam. If anyone can explain that would be greatly appreciated.
Thanks for help, links, info.
F-cam has nothing to do with the back-up cam. It's just a separate app which allows manual control of the cam. You don't need F-cam at all for the reversing cam feature to work.
If you don't have a can bus box then you need to connect the reverse trigger wire to the reverse lights (the orange wire from the head unit).

If car has canbus, it can be solved by adding relay. Activated by reverse light power, relay is suposed to switch some stable voltage to suply camera. For example cigarette lighter voltage can power camera. Here:
