@@richirich1 man I thought it helped but it didn’t 😭 I have 2 CAN decoders and I skipped yellow on both. Radio doesn’t turn on. If I keep one smipped however it comes on. Any ideas ?
@@jakelong2544 use a simple test light and see which is hot when the key is on and when the key is off. I initially snipped the red and thought it would fix it but realized when the cut the key on the screen wouldn’t turn on, so the red to canbus wasn’t my hot like it should’ve been which led me to the yellow. I put my test like to it and found it was always hot even when the key was off, so that’s why I decided to snip it. Put my test light to all the wires even on the factory side. Have to test all the wires and make sure all the wires I your radio wiring harness line up because these things aren’t always accurately lined up coming from China, hence the reason I had to tap a wire (blue) into factory hot wire because the pins didn’t line like they should.
What if you don't have a can bus decoder your car is too old for the can bus? It has to be the battery yellow wire in the harness going to the stereo instead
Mine from eBay was the red and yellow wire were reversed so I just snipped it and connected it the other way around. Red is ACC and Yellow is constant 12V.
Yeah over my time installing these things I’ve learned there are several different variations and mix ups of the wires, but still can’t beat the price.
Hi, I've got an aftermarket fron xhina when i select the canbus option for my car it's saying that the car version it's not available,also not turning off when i get the keys out.
Check the red and yellow wire. See if they are crossed. They should line up with the red from the unit to the red with the car. Pins might be in order. ACC wire controls the on and off with the key. See what your units manual says.
I had problem of battery draining, but radio worked fine. Found out canbus is draining 2mv on a 7.5 fuse. Lets cut that wire :D Update, cutting wire stopped battery drain, but i dont have ac controls anymore .
@@jonasv369 yours is more advance if you have ac controls on your Android radio. Also, confirm which side you snipped. You snipped the aftermarket wire side, not the factory side?
Anybody watching this video and has this problem I can attest that this definitely solves the problem, i was stressed ass hell to firgure out why the imid would not turn off n this video gave me the best solution cut that dam wire!
Was wondering if I can just remove the can bus unit, I don't have any steering wheel controls to link up and the can bus is designed for the newer model of my car. The unit connectors all went together fine but it's that dreaded drain. Another video says that the 2 pin connector with the red and orange could need pulling apart or changing the 2 wires around. Just put a new battery in and want to solve this before putting the unit back in the car.
Yes you can take it out if you don’t have a need for it. It also helps the unit understand when the lights are on so it can go from dim to bright, but if it’s functioning to your liking you don’t have to use it. However, you will need to confirm that the cause of the drain. If you can take the key out and use a test light to test the wires that are still providing power to the unit while it’s off will pinpoint the cause of the drain.
Great work man. Thanks for sharing! I'm getting ready to install one of these into a 2013 cruze ls, base-trim audio system, and I was worried about his canbus thing. You explained it so well! I didn't want to buy this thing, but because it came with all the harnesses, adapter, and a backuo camera, it ended up being a cheaper option than getting a bunch of random separate metra kits and a single din... 😂
Hey thanks! I’m happy it helped. This one gave me the blues and you can tell a bit from the video as I was rambling. But I finally figured it out and got it working with no issues. Good luck with yours! 👍🏾
@@mstbk93 i didn't need to cut any wire on my 2013 cruze. It was plug and play, connect hotspot wifi with your phone, then download the canbus software using the menu.
@@nork_ger8234 so with these it can vary based on model but you usually have to connect via Bluetooth and WiFi or use a third app or the tethering app on the Android radio menu.
I have pin pointed that it was the 2din unit that's causing the drain of my battery. Most of the tutorials out there were of a different 2din unit and the suggestion is to turn off the sleep mode.Your head unit is similar to mine. I found out there's only a standby mode, no sleep mode. So, I'm going to try out your suggestion and see if the parasitic battery drain is fixed. Thanks for this video, mate. Keep you posted.
@@rzrian2386 you have to connect the rca plug and the small wire next it to a power source behind the radio or you’ll have to tap the wire to the reverse light wire in the back.
Friend I'm having a problem that the radio turns on and it plays the MP3 or replace the radio station but I'm getting no audio and then I have to reset it and then it plays audio if you turn the car off and turn it on after 2 or 3 minutes you're okay but if you wait like 10 or 20 minutes once again it turns on but it won't play any sound and you have to do the radio stations again I got a feeling it's the internal battery just like laptops have an internal battery I believe it makes sense that these Android which are basically a tablet would also have an internal battery and it was just too old to hold any power this could be my problem what do you think
Hey how’s it going. I don’t know how new yours is or which model but these things can be finicky. I don’t believe they have an internal battery, as they do have the fuse of the back which is used to keep it active in “sleep mode” to hold some charge while the car is off to keep the memory. Also, you do have a constant source of power which is your ACC and power wire that feeds it power when the key is on and when it’s off usually your yellow and/or red wire. I believe either your car battery is low and not fully charged to 12-14v or there’s an issue with the radio. Might need to factory reset it and also pull it and check the wires make sure none are melted or loosely connected. It could be the radio is going bad, mine in my Tundra the radio portion just stopped working, I hardly listen to radio because I Bluetooth so I don’t worry about it.
I have need to ask, if this procedure will also reset the radio time/date and delete all radio stations after shut off The next question is, that i have a problem that my radio wont turn on after ignition on. It starts only after i start the engine. Any idea? Thanks in advance
It shouldn’t reset anything by doing this. You have a memory wire and fuse that keeps a little power while care is off. You’ll have to check you power wires if not coming on with the key. Possibly the power wire is connected with another auxiliary wire like the cigarette lighter or something that comes on with the car
Try this it works. The head unit receives constant power for memory and presets from the dash side of the harness ( Yellow Wire ). The head unit also receives switched power via the Red Wire. The red wire turns the unit on and off via the key operation. When the unit is shut off, the unit still receives power from the yellow wire. Now !! due to this constant power from the yellow wire, the canbus also receives this constant power . So the unit is live, and also the canbus is live ( Constant ). So, to fix this issue , cut the yellow wire on the canbus and splice it into the red wire on the canbus. What this does is , it stops the canbus from having constant power once the key is turned off. Now, because the yellow wire that is now connected to the red (acc), once the key is inserted and powered up, the red ( acc ) wire provides the yellow canbus wire power to operate. All sorted and no more flat batteries. The moral of the story : 2 units were receiving constant power, and now there is only one. Good luck.
I’m going to give this ago. Just to clarify the red wire will spilt in to two routes basically before it goes into the canbus . One route supplying power for the yellow wire and one route for the red wire?
I kinda have a similar problem to this one. My radio stays on for two minutes when I take the key out, and then it shuts down. What could it be? I mean if it has something with constant power it wouldn't shut down after two minutes, it would stay on, right? Could it be some kind of option enabled in the system settings? I checked that out but I can't find any option there. So yeah, I'm a bit lost now.
@@ivanuremovic1199 do you have you headlights on set to auto? If so, turn them off to see what happens. It could be staying on because of that. Possibly in the advance menu settings there could be a delayed shut down option you need to adjust. Is it draining the battery or just annoying it’s remaining on?

hey ! i installed an a-sure radio. looks completely the same imo. but from the canbus i have a green/black twisted wire and don't know where it goes... i guess to the original canbus too? cant locate that canbus in my VW crafter 2014 though. i hope someone here can help me. the radio works. but i don't know what it will change
If it works fine don’t worry about it. These Chinese made radios don’t always line up given they are universal for so many different vehicles. I wouldn’t stress it unless something is malfunctioning
Well I’m a little autistic in that way. Haha I’ve opened everything up just because I want to know what it does . Haha but it’s fine. Everything works I’m still testing (only one day installed ) so let’s see. I will go to a VW garage and ask them. 😅😅
I have a problem and would be very grateful if you could help me. I bought an xtrons head unit for my Jetta plugged in and it drains my battery let me explain how it’s wired to give you an idea. The yellow wire constant voltage runs from the car to radio, there’s a sub connector with a red and orange wire that connects cars harness to head unit and then goes to canbus. And then there’s the acc wire which is not connected to nothing. Yellow wire and red wire connected to head unit drains my battery. I took out the canbus out overnight thinking it was the one that drains my battery. It still drains my battery. Disconnected red and orange connectors and that cuts voltage to head unit and it stops draining my battery but head unit loses power even though yellow wire is still connected .so with yellow wire still connected but not the red head unit it should still receive voltage and turn in but it does not. Can you please help? I hope my explanation made any sense. Thank you in advance.
My car battery, literally just died. It started with with a jump. Drove for 10 minutes came home to turn it off and turn it on and it struggled. Now i gotta go buy a new battery tomorrow.
Sorry I missed these questions. Yes, if you test the canbus (yellow or red wire) and it’s getting a constant source of power even after the key is off I would cut it. But also make sure the wiring universal wiring harness and if the wires line up properly with your factory ones.
Bro I have the same problem I was so happy when I found this video but when i cut the yellow wire the head unit wouldn’t turn on do u have any suggestions?
@@MarkTruskolaski-bw4vf did you cut the yellow to the Canbus or the one in the main harness? Check the pins to each wire and make sure they line up properly to each specific wire on the factory side. I had to reroute(jump) a wire to the factory side because the Chinese head unit one was off a pin.
Is it the yellow on the canbus or the main yellow wire? What type of car? Some cars especially American cars the radio will stay on until you open the drivers door. If it didn’t work, put it back together and use a test light to see which wire is still hot while the car is off and key is out. These Chinese aftermarket radios and wiring harness aren’t always precisely the same. Could be the red wire.
i installed a head unit 2 days ago, now if i turn on the ignition but now the engine my head unit turn on and drains the battery in about 10 minutes, will this solve my problem ? if not does anyone know a way to fix it ? Thank you!
This is about a parasitic draw of power when the care is completely turned off. What you are experiencing if the car is off but head unit is on and working is simply you have a bad battery with low voltage. If you leave the lights on white car off or listening to the radio and it draws the battery down then that’s just a bad battery. A good battery can hold charge at around 10.8-11.5 volts continuously without draining down If just sitting with the radio on. If the battery drains overnight with the car off then it could be you have something drawing the battery down and in that case this is the video for you
@@richirich1 thanks for the help, my head unit has a fan for cooling, i tested all wires and after disconnecting the fan wire the parasitic draw disappeared, still not sure why the fan was drawing so much power but its solved.
It's possible. You'll just need to suss out the pin out/wiring diagram for the head unit. I mean for basic operation, all you need is B+, ACC, GND and L/R speaker wires. The (well... my) HU harness has all of these. I've got a 10" Chinese head unit that looks like it came off the same shelf in China as the one in this video (just slightly larger screen), and it never came with a CANBUS device like we see in the video, and hasn't needed it. However I am also having issues where it sometimes doesn't turn on/off with the ignition. ACC wire is currently connected through the CIG lighter circuit which seems to have improved the problem but it still occurs occasionally, usually after a day or two of functioning almost perfectly. Cutting the main yellow B+ wire cuts the power to the unit when it wont turn off by the key. This leads me to believe their is a software bug which is preventing an internal switch from activating/deactivating the internal power (so a software controlled switch isn't getting the memo that you've turned the key off and the software keeps providing power to the unit via the B+ wire). It has to be that. OP, I'm almost willing to bet you were still battling this problem after making this video? What I am finding is you think you have a "win" by changing something and it works, then a few days later, the issue returns with nothing being changed. It's like a time based bug in the software which reappears after you have cut power to the unit and then reconnected it again (resetting the time and date again). My unit also refuses to remember the date and time when I manually input them, but it remembers all my radio stations and other custom settings. Just about ready to explore options to flash the unit with a different OS to be honest.
There should be 2, one that goes to the main harness and one that runs to the canbus. If you can’t test it with a test light to determine which is hot, just cut it with enough space that you can rewire it back together if it isn’t the correct wire. Trial and error
Any idea how I could test if my canbus decoder is working? Mine is constantly on so I unplug that 2 wires on the harness and plug in canbus decoder but just get no power at all.
If it’s constantly on you need to located the the tire that’s always hot. Take a test light and check the blue, yellow and red wires and see which one is still hot when the car is off. If one lights up your test light then that’s the reason the unit doesn’t turn off. Then you can do what I did in the video by snipping the wire.
Broooo this was the solution. I tried everything else. This is the only video that shows this solution. My battery actually stays alive now!! Appreciate the content

@ I cut it from the canbas and then it had no power at all so I splice it back together and back to always on lol yeah Ill check there wiring
@ I just read I should cut the yellow from the canbas and connect it to the red acc. Does that sound right ?
@@MarkTruskolaski-bw4vf could work, give it a try. Should turn on and off with the key.
not sure why but it just wouldn’t turn on when i disconnected either of them
If it didn’t turn on them that means you’ve removed on of the power sources to it. What type of car and what exactly did you disconnect?
the only thing for mine is the steering wheel buttons are not working but everything else works
That’s what the canbus is for, you’ll have to program the buttons to it
@@richirich1 i tried that but nothing it doesnt even show car info
Do u know how to root android head unit?
I snipped the yellow wire, but the radio still stays on when the key is out of the ignition.
Anyone got any additional suggestions I can try?
Is it the yellow on the canbus or the main yellow wire? What type of car? Some cars especially American cars the radio will stay on until you open the drivers door.
If it didn’t work, put it back together and use a test light to see which wire is still hot while the car is off and key is out. These Chinese aftermarket radios and wiring harness aren’t always precisely the same. Could be the red wire.
Rhe only things that i have a problem is the fact that when car on,off, the date and time aleays resets. Dont know how to fix
Check the fuse on the unit. Also the memory wire is hot.
I have unit that’s always behind or ahead of time but I don’t worry about it.
Red is ACC and yellow is B+.
i installed a head unit 2 days ago, now if i turn on the ignition but now the engine my head unit turn on and drains the battery in about 10 minutes, will this solve my problem ? if not does anyone know a way to fix it ?
Thank you!
This is about a parasitic draw of power when the care is completely turned off. What you are experiencing if the car is off but head unit is on and working is simply you have a bad battery with low voltage. If you leave the lights on white car off or listening to the radio and it draws the battery down then that’s just a bad battery. A good battery can hold charge at around 10.8-11.5 volts continuously without draining down If just sitting with the radio on. If the battery drains overnight with the car off then it could be you have something drawing the battery down and in that case this is the video for you
@@richirich1 thanks for the help, my head unit has a fan for cooling, i tested all wires and after disconnecting the fan wire the parasitic draw disappeared, still not sure why the fan was drawing so much power but its solved.
That’s good to hear!
So cut the yellow wire from the canbus and its fixed??
@@QuizGameTVV yes saw it was constantly hot so I snipped it
mine doesn’t even turn on
Check your ground wire. Made sure your red and yellow wires line up with one another
Couldn’t you just disconnect the canbus entirely and remove the problem?
@@TrevorM1992 no. The canbus controls the radio working with the lights, reverse, steering wheel switch etc.
@@richirich1 That makes no sense because when you buy an aftermarket stereo like a JVC or Alpine, they dont need a canbus.
@@TrevorM1992 this isn’t JVC, ALPINE 😂
This is China my guy 😂 🤷🏾♂️
It's possible. You'll just need to suss out the pin out/wiring diagram for the head unit. I mean for basic operation, all you need is B+, ACC, GND and L/R speaker wires. The (well... my) HU harness has all of these. I've got a 10" Chinese head unit that looks like it came off the same shelf in China as the one in this video (just slightly larger screen), and it never came with a CANBUS device like we see in the video, and hasn't needed it. However I am also having issues where it sometimes doesn't turn on/off with the ignition. ACC wire is currently connected through the CIG lighter circuit which seems to have improved the problem but it still occurs occasionally, usually after a day or two of functioning almost perfectly. Cutting the main yellow B+ wire cuts the power to the unit when it wont turn off by the key. This leads me to believe their is a software bug which is preventing an internal switch from activating/deactivating the internal power (so a software controlled switch isn't getting the memo that you've turned the key off and the software keeps providing power to the unit via the B+ wire). It has to be that. OP, I'm almost willing to bet you were still battling this problem after making this video? What I am finding is you think you have a "win" by changing something and it works, then a few days later, the issue returns with nothing being changed. It's like a time based bug in the software which reappears after you have cut power to the unit and then reconnected it again (resetting the time and date again). My unit also refuses to remember the date and time when I manually input them, but it remembers all my radio stations and other custom settings. Just about ready to explore options to flash the unit with a different OS to be honest.
there r two yellow wires
There should be 2, one that goes to the main harness and one that runs to the canbus. If you can’t test it with a test light to determine which is hot, just cut it with enough space that you can rewire it back together if it isn’t the correct wire. Trial and error
broo i need ur help
Dont work

It always be your own people 😂
Any idea how I could test if my canbus decoder is working? Mine is constantly on so I unplug that 2 wires on the harness and plug in canbus decoder but just get no power at all.
If it’s constantly on you need to located the the tire that’s always hot. Take a test light and check the blue, yellow and red wires and see which one is still hot when the car is off. If one lights up your test light then that’s the reason the unit doesn’t turn off. Then you can do what I did in the video by snipping the wire.
@@richirich1 will give it a go when I’m home will probably comment again if I’m needing more advice thanks
