Bypass CANBUS to trigger reverse camera mode - All cars - Android Head units

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.

[@AnonymousT7]

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.

[@user-bt7wl9ed3o]

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

[@10aviran]

i have the same issue did you take out the brown cable as he sayd in the video?

[@user-bt7wl9ed3o]

@@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 😁🙏

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👍👍👍

[@Solipsfilm]

Thanks for this trick! Been searching for hours what could have been wrong! Awesome solution thanks ^^

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

[@moviesseriesguy8685]

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?

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?

[@Mike__P]

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?

[@joshG1974]

Thank you for the video, i will try on my android player later on. Thank you for sharing sir 🙏

[@pairojeans]

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!

[@Kelvin555s]

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?

[@benassy69]

It depends on the car. In my case the Canbus box came with the unit fitted on the wiring harness.

[@thangphung]

Hi can you draw a diagram so i can see it better? I have the same problem. Thank you

[@CannibalFerox]

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?

[@Ariz04]

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.

[@benassy69]

Try 12v to the brown wire not only pink.

[@CannibalFerox]

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

[@nicolasamaral6144]

Hi, thanks for that. How come there’s 2 brown cables there? Thanks

[@joshuagoodstein2031]

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.

[@youknownothing3766]

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.

[@pontusborgjonsson1246]

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

[@youknownothing3766]

@@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.

[@pontusborgjonsson1246]

@@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.

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.

[@benassy69]

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.

[@rusanyukaare179]

I don’t see any other setting than AHD, toggled that but it didn’t work neither. Installed in insignia.

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.

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.
