Hi.
I have a Kunfine Android head unit, running Android 10.
I had a reverse camera NTSC, which I plugged into the CVBS-IN-1 input on the HU.
I used the designated reverse camera RCA input, but for me, it was more convenient to use the CVBS input, so I could just open the AUX app in the HU anytime, without having to put the car into reverse. (camera wired to ACC, so it works only if the HU is running as well)
Sadly, I broke the camera, so I decided to buy an AHD 1080p one.
When i plug it into the CVBS, Iget a fuzzy picture, and no signal. I know that the reverse camera can be changed to AHD 720p, 1080p, NTSC and PAL, but how could I change the CVBS input to AHD?
I guess it's default format is NTSC. I couldn't find any setting in the HU regarding my problem. Tried plugging the camera in the Front Cam input, but there isn't even an app for it on my HU.
I tried contacting the buyer and the manufacturer, but so far no one gave me a helpful answer.

I have installed a chinese Pumpkin Android head unit in my Toyota Previa van and after adding an external 3G router and connecting it via an ethernet adapter and an car roof antenna I am now extremely pleased. I get close to perfect streaming video on the road!
I would love to supplement the small Pumpkin display with a roof mounted flip down monitor so the back passengers can watch youtube on a decent size screen. There are many of those on the market, so that should be easy.
However, it turns out that the video output connector of the Pumpkin head unit is only connected to signal of the DVD player! And I stubbornly refuse to go back to juggling with silver disks.
I assume these Android head units coming from China are all very similar. Has anyone ever tried isolating the signal of the head unit's LCD screen and connecting it to an external monitor? If so, please let me know so I can install a monitor that just mirrors the head unit's display.
Regards,
Tinkerspy
I would also love to do this. My factory system output to the headrest screens for back passengers. Since I installed the Android head unit, everything works fine but only outputs to the rear screens if a DVD is inserted - I would love to just be able to duplicate whatever is on the screen so I can play YouTube, Netflix etc. on the rear screens.

Hi, Did you solve the problem?
thanks
I just haven't had time to look at it - been too busy. However, I didn't mention above that my yellow video RCA cables on the back of the unit were mis-labeled and my backup camera ended-up working with a different plug - so I will hopefully get some time to try out what the other RCA video plugs actually do next week when I free up a bit.
Any news about it?

I'd be really interested to hear if it was possible to output video from a source other than DVD to external monitors [emoji106]
Sent from my HTC One M9 using Tapatalk
I've found that some of these Android head-units output ALL video to external monitors and some only output DVD and/or Aux-In to external monitors.
For example, I purchased two GM-specific units - an Eonon GA9180A (MTCE-WWW) and a Hizpo (MTCE-XRC). The Eonon sends ALL video to the video-out jacks (OS launcher, DVD, navi, all apps, etc), but the Hizpo only sends DVD and Aux-in to the video-out jacks.
I know this doesn't help you since you already have the unit (unless you can still exchange/return it), but it may help others that are still in the "research" phase...
dragging this up again..
Does anyone know/think it's possible to pipe video to external monitors from sources other than DVD on these units???
Cheers

Hi Guys
I hope some clever guys can help me out. I bought this head unit.
Android Toyota Hilux Navigation - A9 Dual Core, 3G, WiFi, GPS, DVD, Bluetooth, Radio, DSP, OBD from stop shop running android 4.4
Everything is working perfectly and I am happy with the unit, put I struggle to get the DVR function to work properly. It has a head unit specific DVR app installed that does not even pick up the DVR usb camera that came with the unit. I tried different apps such as Road Voyager that displays the camera, put the moment I press record a green disturbance is displayed and recorded. It does take pictures fine.
The camera view code is H.264 with resolution 640*480, even if I select the video settings to match I cannot record anything than the green disturbance.
I tried this on all three usb ports with the same results.
I am not sure what to do, if it is a camera issue or a setting. I cannot find any setting on the head unit itself to set the camera.
Can someone much cleverer than me maybe help. I cant seem to find any similar information on the web.
thanks
" It does take pictures fine "
What resolution are the pictures?, check this out and use the same resolution for video recording.
Some cheap cameras only support single resolution.

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.

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.

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!!!

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.

Hey guys,
Ive got an Joying JY-UQ135N4G headunit with android 10.
As I have no signal cable for the reverse gear detection, I connected my rear camera to AV IN. When connecting the camera to AV IN there is luckily no need to connect the orange signal cable for reverse gear detection.
Unfortunately the screen does not show any parking lines when using the default "aux" app. (The rear camera app can't be used as the camera is connected to AV IN)
Is there any alternative app that I can use to get the parking lines?
Many thanks & Best regards!
there is definitely an application. Buy another camera anyway because static lines are embedded in the camera chip. I had a DVD reversing camera attached at home and there were static reversing lines in the picture. I have dynamic lines on the radio directly in the radio (application and dynamic rotation of the line is controlled by CANBUS in the car). And I have statics on the camera. I can add pictures. Some manufacturers also offer reversing cameras with the option to cancel static lines or rotate the mirror image (you can cut a thin cable). You can find such cameras on Aliexpress. Or do you want a link?
Hi, the camera doesn't have lines integrated, otherwise they would show up, when the camera is connected to Aux/AV IN. My headunit does have the reserving lines integrated, but only when the camera is connected to the rear camera input, which can't be used as I don't have the necessary signal cable available at the headunit.
When I connect the camera to Aux/AV IN input I can't use the "rear camera application" as the camera isn't connected to that input. I must use the Aux application, but that doesn't have the reversing lines integrated.
Does the radio have no reversing camera signal connectors? If so, you can connect + 12v from the reversing light. This is the signal to start the reversing app. It's for a car that doesn't have a canbus. If you can't find the app with guide lines, you have to buy another camera that already has integrated lines on the chip. If you buy such a camera, the reversing lines will show you both AUX / AV IN and any device
Sorry, but did you even read the whole text ? I thought I described clear enough what I already tested and what the exact problem is.
hi. I understand what you tried. Good luck looking for an app. If you can't find it, the only option is to buy a camera with guide lines to display them on AUX / AV IN. Stay healthy ...
