- Hi guys,
I just bought a Junsun V1 Pro Android head unit from Aliexpress and of course it has some issues. The unit came with a CAMBUS decoder for my car but it seems it does not detect the reverse mode, meaning the back-up camera / reverse camera cannot be activated. In this video I will show you how I managed to bypass the canbus and trigger the reverse camera mode. - Věda a technologie
This has just saved me hours. In my case my Android 13 head-unit booted straight to reverse camera function on switching on the ignition of my 2013 Corsa VXR. I Removed the orange wire from the can bus box and it worked! Thank you
i have the same issue did you take out the brown cable as he sayd in the video?
@@10aviran I just cut the "orange" wire thats goes to the canbus box and taped up each end! I didn't want the camera function.
Very helpful video, I was able to use the info you shared to install a similar unit on a Hyundai Santa Fe, the video was the last part that wasn't working, and now it's all fixed 😁🙏
Glad it helped.
A lot of reading and watching then it lead me to your video. Problem solved. Thank you for sharing!
Thanks for this trick! Been searching for hours what could have been wrong! Awesome solution thanks ^^
Thank you, thank you. I'd been trying for weeks to get my system to work and couldn't understand why not.
I have a corsa 2016,and camera constanly saying no video imput? Do you know why this is? Also keeps flashing up heating picture on the android stereo,which is annoying,but cant stop it. Any ideas please?
I have issue with mine too. I have mitsubishi lancer gt which comes with Rockford sound system. After selecting my car model in canbus protocols “Car settings” app appeared in apps which have all audio option which were on my factory headunit. After setting sound equalizer,surround ect..on car setting app it resets automatically doesn’t save settings. All settings on android headunit and its own Equalizer settings are saved and not resetting except canbus “Car settings” app. Can you help me with that?
Thank you so much ! i spend hours on this problem and now everything is working fine thanks to you !
Thank you very much! I had the same issue with my 2015 Kia Sportage today and your video helped me. The brown cable coming out the canbus adapter was dead so i used another wire which has the reverse signal.
Hello, could you tell me what cable did you use?
@@TenteSanzTente_Sanz there was a wire labeled with "reverse" so i used this instead
@@AnonymousT7 Thanks, but the problem is that my cable does not have one labeled with reverse, so if anyone knows how to tell me how else I can look for the correct cable, I would appreciate it. My Kia Sportage is from 2019, I installed a radio with Android 13 from Aliexpress, everything works fine except the reverse camera.
hey there 😊 could you maby give me some advice, i have also installed android radio, by my ac is stuck at cold, so i dont have heating in my car, everything is ok with heating system because it works on original radio. do you maby know what could be the problem
Hi Adrian, thanks for this post. I had te same problem with my Davilion Head Unit in our 2012 Mazda CX-5 and altough not original configured for Canbus connection, I ordered a set on E-bay with the cableset and de Canbus convertor. Almost everything, also the central knob works on the screen. The reverse camera wasn't working and with your trick, I got the reverse camera working.
Problem was after leaving the reverse gear, that the screen went black and the Android Auto screen didn't came back for a couple of minutes. Then I remembered that I've added a "noise" filter to the rearview camera power wire.
The camera trigger-signal dropped to about 5 volts and then slowly dropped further (probably caused by a capacitor in the filter). At some time after leaving reverse gear, the Android screen came back. So I added a 1Watt 180 Ohm resistor on the camera signal line (to ground) and the Android Auto screen comes back within half a second.
Problem solved and again, thanks👍👍👍
Hi, thanks for that.
How come there’s 2 brown cables there? Thanks
I know this is super late, but he folded the cable in half and stripped a section to connect so as not to mess up the pin if he wants to restore it at a later date.
There is a video where the person cut that brown wire from the canbus connector and used a butt connector to connect the 12v wire to both input and output, sending 12 volts to the canbus unit and the radio. Why did you remove the wire from the canbus connector?
Thank you for your helpful video, I had a Japanese imported vehicle and with the help of your video I was able to make the factory reverse camera work!
Thank you for the video, i will try on my android player later on. Thank you for sharing sir 🙏
I think I have the same radio (just different brand, identical interface). I tried to bypass the canbus but I had no luck: the radio doesn't switch to the reverse mode. I tried both putting 12v or 6v to the pink wire on the back but it doesn't trigger the reverse mode. Do the radio also wants the video signal in at the same time in order to switch to reverse mode? Or are there any radio configuration to setup?
this is my exact problem right now.
i just installed the same head unit for my mom's 08 rav 4.
everything works great but then, as i was hooking up the back up cam, it just doesnt activate.
I am 100% sure that everything is wired up properly, and even tried a new wire and cam thats gonna go to my subie. still does not activate the back up cam when when put into reverse. i even tried switching up all the yellow video plugs, still nothing.
Try 12v to the brown wire not only pink.
I eventually made it. I noticed that the radio plug is not connected to the car's 3rd pin (which is the 12v reverse gear). Moreover, the factory car's camera works at a different voltage and there are settings to make on the radio. I connected the 3rd pin to the pink cable. Then, I connected a small DC transformer's input to the pink cable and the ground cable, and I connected its output (6v) to the camera. Finally, I activated the back camera in the radio's factory settings
Hi, I bought Junsun V1 6gb recently for Mitsubishi Pajero. It did not came with any Canbus. Some of my function were not working so I had to sent it back. Otherwise I liked the unit. Did your canbus came with original package? or had to buy separate?
It depends on the car. In my case the Canbus box came with the unit fitted on the wiring harness.
I know this is old post, but im wondering how to fix a low voltage for the car. The back up camera works when its not running. But when you turn the engine ON, it will say NO SIGNAL. Simply the voltage drop. Need help please
visit some proper electric workshop, probably you have problems with wiring or (not sure) an alternator.
Hello, I have a Chinese screen for a Mercedes CLA and my problem is that when I'm in the android menu the rear camera it's doesn't work buy if Im in the NTG menú (original menu) of the radio the rear camera works perfectly. In resume it's doesn't switch in automatic between OEM menu and Android menu. Can I solve the problem with the solution of this tutorial? Thanks
Hi can you draw a diagram so i can see it better? I have the same problem. Thank you
Hi, with Hyundai Santa fe 2016, I have the same problem, only the different is that I have a original camera and I don't have the rêd wire coming from the back cam.
You get yours working? I am also Santa Fe 2016 and pretty sure this is my issue. Its not triggering the reverse mode.
Same issue Here with Kia Sportage. Did you get yours working?
I have the same problem with my Suzuki Ertiga car 2018 .I managed to install the reverse camera to RCA rear AUX using pink colour wire as trigger wire but it doesnt go automatic whenever I shift to reverse.What seemed to be the problem? Thanks for sharing your knowledge.
Which Pink wire? The one from the Main wiring harness or the one next to the yellow RCA?
My unit turns on revers camera no problem, only some of the time....
It seems I need to hook up to the reverse lamp as well???
Someone please advise/help
Which colour wires you remove from the can bus box
You can see in the video... the Brown ones.
So you connected both brown wires to the red wire coming from reverse bulb? @@benassy69
I have a similar issue with my Honda and a TS10 headunit, the canbus isnt picking up the reverse. I have a feeling maybe its a manual car. I will be splicing the camera 12v into the reverse light socket and following your method to remove the input to the canbus for reverse 12v.
And i bet you have the red one back in your taillight. Take that of and just put in whit the lil trigger and will work
@@pontusborgjonsson1246 it ended up being the reverse light switch trigger in the manual transmission casing. Swaped it out for a new one and it all works now. I did slice the wires for the camera taking power from reverse light globe. Wonder if I should remove the power source and drive it off the canbus.
@@youknownothing3766 Try it i see alot use the trigger wires also use for the power becuse its a power cable.
Also you have canbus so it tells the radio its R time and trigger wires on stereo gets 12 v and that go to the camera because you have the trigger on the power cable.
salut, am si eu o problema asemanatoare la un logan 2016 cu o navigatie de pe aliexpress, tot wiring-ul este facut, am semnal pe firul de reverse pe partea de trigger, dar navigatia tot nu face switch la reverse mode ( din comportamentul navigatiei in momentul in care mut pe marsarier, butonul de home devine inactiv/nefunctional si icon-urile din bara de sus dispar). Daca ai putea sa ma ajuti cu un advice? Mersi frumos
Salut. Aici din păcate suspectez o problema de soft a tabletei. În mod normal ar trebui sa funcționeze corect. Ai încercat sa contactezi vânzătorul?
@@benassy69 la fel suspectez si eu, ceva problema de soft, o sa incerc sa ma "cert" cu chinezii de pe aliexpress :)). Multumesc frumos de raspuns si de promptitudine
I have installed dual dash camera on android player of Chevrolet cruze. Recording is fine with both the cameras. But when I put on reverse, it shows only blank screen. All the connections done properly.
Did you connect power from the reverse light to the backup camera and selected in the Radio setting, the correct type of backup camera that you used.
if it blank screen - possibly you haven't connected brown-wire which is a trigger
I have a flickering issue with my reverse camera. Do you know what could be causing the flickering/fuzzy image?
Hi, I have a video on my channel addressing this exact issue. Thy disconnecting the negative (black wire) from the reverse light.
@@benassy69 I just watched your video. I'm scared it might be caused by another issue in that the camera isn't receiving enough power. I have seen other videos of people installing a 12v relay to the camera wiring to fix the flicker issue. But I might try your ground wire disconnection method first. Thank you
Probably just the camera setting you just have to put it into ntsc
Thank you for this buddy but I am still trying to figure why mine is not working, I have attached the red wire from the camera to pin 3 I believe is Accessory wire at the back of android unit, at the back of the vehicle I have connected the video cable from the camera to the long cable connection and the connected the ground cable, red wire connected to reverse light. with all these but don’t get video, only trajectory lines. I have canbus and my unit is by T’eyes. Is there anyway you can help with diagnosis. Thank you again.
If you consider you have wired everything as in the instructions provided, then I would firstly make sure the settings are correct. Go to settings and change thru all times of cameras. 720p or 1080p or AHD or CVMP.
I don’t see any other setting than AHD, toggled that but it didn’t work neither. Installed in insignia.
Do you have a multimeter? Try and see if you have 12 volts at pin 3 when you put the car in reverse.
@@benassy69 yes I have done that and I can confirm I have 12.9v when in reverse
Where do you take the 12v for the camera? Is it from the rear reverse light?
Salut Adrian , am aceiasi problema cu Hyundai ix35, nu am inteles bine de unde ai luat alimentarea pentru firul maro. Direct de la becul de marsarier?
Salut Daniel. Da de la + becului de marșarier.
Multumesc frumos
Hello if i conect to power my unit triger the camera but it stays with the mesage no signal and a black screen with the parking lines , wich cables i need to remove to conect to the red one i am a little bit confuse .thanks
I think your camera is connected correctly. Try changing the type of camera from CVSM to AHD 720 or 1080 from settings menu.
Try to find look everywhere can't find those settings for the junsun v1
Are you using the factory backup camera? or after market?. If you are using the factory backup camera, can you please make a video of how to re-wire that?
I am using a generic 720p AHD analog camera. Connected via RCA and powered from the rear lamp
Salut , Oare poate fi conectata direct camera de fabrica ?
Da dacă ai pe mănunchiuri de cabluri mufa aferentă. Eu la acest model am avut.
Salut și mulțumesc de răspuns, am comandat același model astăzi, aștept sa vina și o sa verific , aștept și un răspuns oficial de la producator
@@benassy69 salut , nu am mai avut timp sa postez comentariul acesta pentru ca am fost în vacanta, navigația a venit cu un mănunchi de cabluri care avea direct shunt făcut de chinezi( probabil au citit unele comentarii). Dacă te rog îmi poți spune ce cod ai folosit pentru meniul de la canbus și ce configurație ai selectat pentru a afișa cât mai multe informații corect pe tableta?
I have same canbus and when I connect cunbus to my car get crazy😂 maximum light and seat belt light starts blinks and a song signal for from the car😢 my is veloster hyundai
Hi SuoerBrunh, you have the wrong can bus decoder, I have the same problem on a 2014 Mazda 6, replace the canbus box with the rught one and works perfectly fine.
Ciao, da dove hai preso la corrente della retromarcia? C'è un modo per poterla prendere sotto il cruscotto?
Ciao, ho l'alimentazione dalla luce di retromarcia posteriore tramite il cavo rosso della camera.
How did you determine the reverse lights power?
By power you refer to voltage? If yes with a multimetre.
I thought i had the solution with you video, but still nothing, connected 12v straight to brown pin of head unit and it still wont change to reverse mode...Im out of ideas. great video though!
same problem here...
Hi i have the same problem you can send me a diagram that i can see it better thank you
Hi mate. Do you know how to turn of the rear sensors?
Hi. From the car or from the head unit?
@@benassy69 from both mate. The noise is driving me insane 😂😂
@@garethharrison3843 go for head unit settings, must be somewhere under "advanced settings" (not sure which head unit is used by you)
I have same issue but not comfortable messing with the CANBUS, Is there a simpler solution? 😅
Yes, there is. Go to a car audio service which has technicians that are comfortable messing with it :))
salut Adrian am aceasi prblema si acelasi tip de masina nu pot conecta camera marslier, imi poti detalia te rog pasii de urmat ?
Salut Arpad. Te rog raspunde-mi la următoarele intrebari: 1. Camera e cea originala a mașinii? 2. Când bagi mașină în marșarier îți apare pe ecran no signal sau aparatul nu reacționează deloc? 3. Este tot un Android China? 4. Ai cutiuță Canbus pe cablurile de conectare?
I have the same headunit as you from china.. It has a canbus and I got the supply for the camera from the radio headunit itself.. i basically condemn the power wire along the rca video cable
So you give 12v to the camera from the unit itself? Not from the back lights? Can you please tell me which cable of the unit have 12v?
@@nikostsigaridas9365the brown wire in my ts7 android headunit has the reverse supply 12v. You can use multimeter to check the voltage when reverse is being triggered. I did not use the small red wire on the rca cable.
For mine on my 2014 Mitsubishi lancer GT when I connect the original camera with the radio it just stays on the camera view I can’t get out of it anyone had this problem and found a solution?
I have the same problem but I don’t have that canbus module, it’s connected directly 😢
Hy Sir, how i can learn my canbus to my car?
Am urmărit filmulețul dvs. Am o unitate asemănătoare dar fără canbus. Am conectat totul conform instrucțiunilor dar totuși nu am niciun feedback de la cameră, nici măcar acel ecran negru cu mesajul "NO SIGNAL". Apreciez f mult dacă îmi puteți da un sfat. Mulțumesc.
Bună Laurențiu. Înseamnă că unitatea ta android nu primește 12 v pe firul de declanșare camera. De obicei e un for maro sau roz marcat cu camera sau backup
Does anyone with a 2019 Kia Sportage know where to connect the brown cable so that the reverse camera can be seen??? Screen with android 13 from aliexpress.
It could be something you need to activate via factory setting, or you have connected it to rear light power which is something that you do with non canbus decoder models...
Theres an excellent video ..."How to wire reverse camera if your vehicle has canbus"by AudioVisionUSA - worth a watch.
i tried what you did and it doesn't do anything. still says no signal.
Vă salut! Unde vă pot contacta? Sunt nelămurit într-o privință. Vă mulțumesc!

Sal Adrian te rog frumos îmi poți spune cum recuperez telecamera de serie de la Hyundai Tucson xpossible 2016 ca nu inteleg unde legi firul din spate cel roșu am încercat și tot nu funcționează poți să-mi trimiți un video în română poate înțeleg mai bine mersi frumos
Nu știu la ce te referi prin telecamera de serie? Adică camera originala din fabrica a masinii?
Thank you à lot
Hi, here is what happens on my radio Android 13.
Installed on a Suzuki XL
There is a yellow wire ,hot all the time.
No wire to accesory, so I run a wire from acc wire and run it to a red going to canbus/radio wire
Everything work BUT.
Radio wont boot.
If I remove key, eadio will turn off, when star car, radio will be on on radio app will start, where I shut down the car.
If shut down car removing key, same thing, will come on the app the radio was.
THEN: NO BACK UP CAMERA
NO LOGO BOOT
I caN see video from rear camera connected to the csbv connector and feeding camera with 12 volts.
Watching videos in YouTuve seems like my radio has some missing setups.
Radio Brand is...JAC
Ciao
Ho una radio molto simile alla tua, ho una Hyundai Tucson 2019 con retrocamera originale, la radio non fa niente quando metto la retromarcia, l’immagine non cambia e non viene neanche lo schermo nero , è come se non arrivasse il segnale di quando inserisco la retromarcia , hai qualche idea?? Grazie 🙏 😊
SÌ. non sono presenti 12 V sul cavo di attivazione del retromarcia dalla scatola Canbus
@@benassy69 hai qualche consiglio su come possa sistemare la cosa? Dai connettori della mia auto non ho idea quali siano i cavi che danno il 12 V quanto inserisco la retromarcia!!
@@benassy69 hai qualche consiglio?? Prendo un cavo dalla luce della retromarcia e lo porto fino alla radio? O c’è un sistema migliore e più facile??
I did a factory restore on mine and now my controls are backwards and I can’t restore the car settings lol
You can manually overwrite them in the SWC menu

@@benassy69 Hello! Great video! I can't get the factory reversing camera of a 2015 Hyundai IX35 model to work because I have the same canbus converter as you! Could you attach photos of how the car's multimedia cable is connected to the car's factory reversing camera? The seller provided me with all the cables, but no matter what I try, the multimedia only switches to camera mode, but the camera does not provide a picture. I really need your help! Thanks!
@@zsoltmolnar6434 Szia Zsolt! Unfortunately I cannot make a photo because I have already installed the unit and second I don't have a factory camera but a aftermarket one instead. Your problem comes maybe from the Unit itselfe. Have you changed the camera input format from the menu? AHD CVAs TVI etc?
@@benassy69 Helló! Yes! No camera singal. :(
And 3.25 in isch is the problem if have canbus do not put the red on the tail light. You put it on the other trigger. Tada fix that problem the canbus do rest after and tell stereo in R 👌
Thanks I will try it. I just have to find my trigger wire on my Lexus LS430
I’m trying to connect my backup camera to my new android system
Be careful, guys. Very Important thing:
You can't join "in between" of brown Canbus wire, cause Canbus can be fried of 12v, it operates much lower volts!
That's why he cut out a brown wire FROM canbus, making a bypass of it.
Direct 12V trigger - maybe will work ok, not sure.
There is a another video on youtube showing exactly this, and apparently everything was fine. So I'm not sure what to do with mine.
@@Mike__P true, but a friend of mine done this thing on his own ford focus 2 (2008) and then send me a picture of blown fuse and some fried wiring. Just by his luck - he didn't killed a HeadUnit and it still working fine till this day (from 2022).
