Hello. Recently I have bought 8227l 8" Android 8.1 head unit from Aliexpress, installed it using provided adapters and everything works fine but the head unit won't turn off when I pull out the key. When I turn it off with phisical power button, something like Always On screen with time and date shows and button lights is still on. As I can understand powering of the head unit is controlled via canbus decoder. But when I plug out canbus decoder nothing defferent happens, only radio doesn't show car parameters like fuel consumption, rpm, milleage etc. Can someone help me? Is it something wrong with wiring?
What does the reseller suggest?

There are two type of +12v, one is permanent and another one is from Acc key, you may have switch that, try to look into that.

There is a mini connector on the main cable. If you detach it, unit will shut down when key is removed.
Did anyone figure out a solution for this

Hello, I recently bought this head unit and I am now facing the following problem. It won't turn off! To be specific, for as long it gets power from the ignition switch, if I turn it of it will retract screen, say bye bye etc but the clock on little screen, button illumination and any power supply to amplifiers electric antenna etc will stay on. Does this happen with other brands too? Any help would be highly appreciated.
Anyone to tell if this applies also in his head unit, even of another brand?
Try to switch the acc and power cable on the connector
Hi,
I've bought a new Head Unit, and I wired everything on the car.
It's working like a charm, but, there a big but.
The Head Unit which should go to sleep / deep sleep or whatever when I remove my car key after 30 seconds, stays on.
For the time being I've unpluger the ACC cable (the red wire) so that the Head Unit only receives power when the car key is plugged in.
Do you know why am I facing this Issue and how to resolve it ? I had hope to enjoy a fast boot and not a full boot everytime I use my car.. it would be nice
I have another question also, if you know about it, I'm trying to get the light buttons always on, because they're not very visible to me. Si I went to the special menu (with the 126 code) and tried changing the parameter "Power LED control" to "By Power" instead of "By head light" but they still won't turn on unless head light is on. Am I missing something ?
I'm not sure what head unit you have but a) what is your amp wire from the head unit connected to? B) there's is usually an illumination wire, what is that connected to?

Also do not know what head unit you have but it sounds like it is not wired up correctly.
If you dont get much help on these forums maybe go visit an auto electrician as they should be able to advise further.
I've recently purchased a Ford specific xtrons head unit which can with all leads and canbus box! However the unit does not power on and off when the key is inserted and will randomly power off while driving! Also the lights on the head unit do not switch on when I turn on my lights and the screen also doesn't dim! Any help would be much appreciated thanks
Hello,
The other night I was messing with my HU sold\made by XY Auto and the model is the 8227L_Demo. I must have cleared something in the factory settings because now my on screen climate controls are not showing. I would try to perform a recovery on the unit but it seems there is not any way to get into the recovery. My physical climate controls on the chassis still work. Picture attached of the entire unit I purchased back in 2018. All in all I think I messed something up with the CAN BUS in the software? All the wiring is still connected properly and no damage.
Anyone have any experience with this and maybe know how I can fix it? Anyone know how to get the unit into recovery mode? For recovery mode I've already tried disconnecting the power from the HU, holding in the Reset button while plugging the power back into the HU (I did have the ACC turned on while doing this) still no recovery mode. I also checked for a chip? C7 or something like that on the MB but I could not find it do to a short out as some others have stated it works on their HU's/
When I go into the Car Settings Menu, I logged into Factory Settings and I Properly set the CAN Set to Honda. I then went back out of the Factory Settings and then went into Car Settings where it says to "set in car". I pressed that button and then I get a message of "No Original vehicle settings function"
Any help, guidance, etc. is greatly appreciated and thanks in advance.
(I emailed XY Auto 2 days ago and no response from them yet)
From reading the posts, what has been considered and tried.
What do you want out of xda
Are you sure you have selected the correct CanBus type (e.g Bagu, AnyYuan, etc)? I doubt you will get a response from XY Auto as these 8227L units are for the most part unbranded generic head units. Have you tried contacting who you bought the head unit from (the reseller)?
I recently installed an Android Head unit in my 2012 BMW 128. I have the HiFi non HK stereo.
Sound works fine. Steering wheel controls also work (set for an E90 to match the canbus decoder that was included. There is no option for E82)
GPS/WiFi, etc all work as expected.
The issue I'm having is that when I shut the car off and lock it, it never goes to sleep. Normally it takes 15-20 minutes for it to finish all the checks and enter sleep mode but with the power connected to the Android unit, that process never stops. I've waited hours and came back to it still making noises, the start button periodically lighting up, etc.
If I disconnect the power cable to the head unit/canbus controller, the car goes to sleep as expected. I have gone into the factory settings and disabled sleep mode which causes the stereo to have to boot when you start the car but that also didn't resolve the issue.
I have not connected the extra yellow cable to the fuse panel - I understand that's for clock/radio presets but those are not of concern at the moment.
I can't find any settings on the head unit that would be causing this. The yellow power appears to flow through the canbus controller to the head unit because if you disconnect the canbus controller the head unit will not power on so I tend to think it's likely the canbus controller that's the culprit.
Just wondering if anyone else has had a similar issue and how they resolved it?
Connected the yellow cable to the power for the 12v outlet and the car goes to sleep as expected.
Bumping my own old thread.
Connected to fuse #2 in the panel and the car would sleep and the stereo retains clock, etc but I get a battery drain warning.
Went back to 12v outlet and no more battery drain but it cold boots every time I start the car.
If anyone stumbles across this and has a solution please let me know!
