PX6 in VW Transporter T5.1

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...
Cheers

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.

Front Camera (RCA) app needed for Topway TS9 android head unit

Hi, all. New to the forum.
I have a KUNFINE head-unit which appears to be based on the Topway TS9. It has multiple RCA video inputs, one of which is labeled front camera, but I do not appear to have an app installed that can make use of it.
Ideally, I'd like to install an AHD cam in the front and use that with a DVR software. Searches only turn up USB cam apps, but the vendor advised me that it is possible to use the F-Cam input for that. I just don't know where to get the right app.

I have a KUNFINE head-unit, I think it's a Topway too. I just looked though my settings and do not see that option. I had planned on adding a front camera but had not looked for it yet, since I have been dealing with other issues. What system version does your head-unit have?

HELP REAR CAMERA OWNICE K7

Hello its possibile help for visualization rear camera video with ownice k7 . I have installed in renault kadjar with ISO cable and canbus but rear camera dont start when i insert rear gear thanks

This is also the case with me! Today I installed the Ownice K7 radio. It is a big disappointment that there is no picture of the reversing camera. Are we doing something wrong?

Toyota C-HR hybrid is my car, if that's interesting.

no in my opinion the 32pin iso cable where the original rear camera cable passes is not well wired because I saw that there is no power to the rear camera. we have to find the problem and solve it. if you succeed let me know how you solved.

I haven't had any results yet. Maybe you should try pairing the canbus first. It installs an extra app with car setup options.
But I have tried in vain so far, there are too many choices. Although I found my car on one of the models, I didn't get the picture of the reversing camera.
The seller's response today is:
"Did you connect the Cam in port on our power cable to the Rear camera input port on RCA cable."
Of course there is no RCA, there is a canbus.

Maybe that's the solution?

I did it, but nothing happened ...
There are two CAM IN RCA connectors on the POWER harness. I tried both, although nothing from the factory radio is connected to one of its pin connectors.

Hi, is your hu with 360? If so, then k7 will use the 360 cam instead of your existing cam. The reverse cam will only work if 360 app is not running. Try restarting the hu while in reverse. Then as the hu boots the reverse cam will show at for a few seconds.
If hu did not come with 360, then check the reverse cam type.
The rca connector is in B harness not power. It is brown color. Then if you have canbus, it should be automatic. Make sure your reverse cam is terminated properly ie. Power and ground.

i have TEST YOUR SOLUTION, i don't have 360 camera , i have CANBUS WITH BROWN CABLE but i when insert rerar gear not appear. if i open app for vision cam the message is NOT SIGNAL.
i have test at connecting at aftermarket cam and i see image in app. where is the problem of my original cam??

No, there is no 360. But only part of the problem is that there is no reversing camera image!
Unfortunately, nothing works about CANBUS, only the left side of the steering control.
The seller also sent a picture of the camera connection. I repackaged the radio, checked it, everything is as pictured! It also sent about CANBUS type selection, but it is.
No door opening, no radar, no air conditioning, nothing ... Who doesn't have a reversing camera, do the other things work?

I have write to winlink ownice and the result is the camera original not work and seller send me a camera sony! When arrive i test

The problem for me is in the canbus decoder not support rear camera original. Because the original camera is 6v but radio send 12v

Considered installing a voltage regulator and using the factory camera, like for Toyota models?
The knockoff won't be a Sony...

For me, Toyota C-HR hybrid is my car. Unfortunately, nothing works about the CAN BUS, not just the factory reversing camera. But I think the Toyota camera is 12V. Now I’m there for the seller to contact the engineer to see if the smooth and hybrid CHR require the same CAN BUS. (There is a different type of hybrid in the Factory menu.)

Today i have test some solution but not work. I have connect rca cable cam at other rca radio connector VIDEO OUT and the video of rear camera when I open apk AUX is work!!! But if I connect to rear camera rca and positive on pin 4 radio back the cam enter in rear vision but not see image. Repeat i connect rca cable cam to AUX VIDEO and red wire Cam ON positive and image work good but I connect rear cam rca at RCA CAM INPUT OF RADIO and red wire at pin. N4 of radio the display on the rear camera but not image!!!! Help for me

Has the promised camera arrived? Now they promised me one too. I hope this already works, although I would have preferred the original to work!

Funny mixture of topics here.
You need +12 V on the reverse cable of your head unit as soon as you in reverse gear. This is just to tell the hu that you're in reverse. You can grab the reverse signal from can bus box or from the wiring harness of your car. Use a multimeter to verify if you get the 12 V. Search for the pin description of the original OEM radio.

I doesn´t make sense to just guess... If we know the unit, we could find something.

This Head Unit not a Topway platform, so password be not 7890, It's look like FYT platform, maybe take some system info can easier to judge

I thought something like that as I saw your desktop with the buttons on top.
We are talking about a Klyde derivative, with some different things inside.
Now it´s clear, this is a RL9Ac, so my expectation was correct.
There are only 2 PINS available in this unit:
7890 is the first one to enter the system information
8861 for deeper settings menue
There is nothing else.

possible that it is so lacking in options? when the px6 is also too full of options to set

This unit is so different from the ones you seem to use...
All options are available with these 2 Pins. There is no need for any other settings page.
Edit:
The RL9Ac are the pendants to the rotatable screen used in Klyde KD-1280, which are delivered with the RL7Ac MCU. The main setup menu is the complete same in both.
There are already some threads in this forum. Just some guys don´t understand this unit and the features with it.
It´s completely different from all other currently available unit.

this radio has two RCA connectors with written VIDEO IN and S. CAM IN in yellow color ..... I wanted to connect a front camera with RCA connector .... but then how do I select it on the screen?

Well... If you want that the front cam act like a dash cam... no, that doesn´t work.
If you want to have the front cam acting as a parking cam, you can activate that in the settings and it would be activated for some sec. after you leave the reverse gear.

no for the dash cam I have already ordered a dash cam to be connected to usb .... I also bought a simple camera to be inserted in the front grill but it is rca .... I do not have the icon on the screen to activate it .... that's the problem

the radio being specific for the captiva is all plug & play .... but there are some scattered wires that the Chinese say should not be connected .... I am attaching photos .... I had number 5 translated and it is "camera power" but I don't know if it refers to a possible front camera to be powered .... the camera behind the machine works without problems and without using any rca connector.

For front camera i have buy this.... I not want that use like dvr or dash camera..... Only parking camera

My car have front and rear parking sensor

Questions Joyx autoradio Android 12 cameras 360

Hello,
I got this unit from Amazon:
JOYX - [6G+128G] - Android 12 IPS Car Radio Suitable for Ford Tourneo Transit Custom (2013-2021) - Wireless CarPlay / Android Car / DSP - LED Camera & MIC - 9 Inch 2 Din - DAB SWC WiFi Fast-B oot 360-Camera​And this accessory:
4-part AHD cameras must be purchased separately, ASIN:B095HQSV15
1) When I connect 1 of the 360 camera, the front one, it shows as if it's two video feed in one. Let's say it's not showing 1 image properly, but lines and what seems to be noise.
What am I supposed to see when connecting 1 camera only, a proper video feed for the front camera?
2) It says AHD camera, on the autoradio there are various "camera settings" about which format is it (NTSC, PAL, and 2 different AHD with different resolutions). I tried we get an ugly signal from all but one AHD (signal not found for the latest). I am supposed to change or it should connect straight of the box?
3) We tried to have the rear camera provided from the head unit box (not the 360 ones), we also did not get signal despite a cabling that works (let's say the power was tested in each cables and it should have been done properly). The camera works on another vehicle. When engaging the rear on the gearbox, we do see the lines but no video signal.
Any idea?
Thanks for any help,

The vendor sent me a video showing one need to click on settings/video/ and change a setting to AVM.

The vendor activated using the QR Code. I had to sync the options, it's now activated.
Problem is, the application for 360 crashes every few seconds.
