andriod head unit factory setting menu

I have installed an Andriod 4.2.2 Head unit in my 2013 dodge challenger, this is a unbranded unit,
I have been trying to get my SWC to work.
I can enter a "Factory settings menu" with the Password "126" this allowed me to change logo etc.
there are many options under canbus settings in this menu under "Applications"
Mine is currently set to jeep (union) there are other options ie jeep hiworld , Chrysler and many others.
I have searched for posts that explain these menu,s with no success.
My handbrake canbus radio interface works OK but not the SWC.
can I do any harm trying other settings?
The supplier of the radio just tells me to hook up key1 and key 2 wire and ground, however my radio installer
tells me these are only for resistive touch buttons.
The unit was supplied and installed with a canbus adaptor.
Can anyone help me or point me to a thread that explains this.
Thanks Mike

Its a HuiFei type unit (its not unbranded - there are about 10 brands), read the HuiFei thread.

Most steering controls work by sending a certain voltage down the wire that your head unit interprets. Like 160 mhz is play/pause while 190 mhz is volume up. (those numbers arent accurate, but you should get the jist). This type of controls is a direct analog type and what the chinese units use to intrepret your control data.
Some cars,I'm guessing yours is one of them, use a digital signal that can't be interpreted by the analog wires that come from harness. You'd need an SWC interface as a go between for your car and HU.

Or a CAN Bus adapter from the manufacturer of his unit. but as I said earlier all the info he needs is in the HuiFei thread . . .

Re Headunit
Thanks guys, so as I interpret this I need a further adaptor additional to the canbus adaptor supplied by the head unit manufacturer.
I would still be interested in finding an explaination of the factory settings menu ,the one you need the password to enter, as I can not find a post on this?

Hi everyone, I need help with my HU. I followed the factory guidance to set up the wiring and installation but my camera lines appears 90 degrees (from the left) instead of the center. I have tried mirroring, no luck. Please see picture. Can someone help me please.

Android Head Unit choice for Skoda Octavia 2

Hi,
I would like to install an Android head unit to replace the Swing car radio in my Skoda Octavia 2.
I hesitate between 3 models:
-LJHANG PX6 7" 4/32Go is PX6 a good choice compared PX5 ?
-ZNY PX5 8" 4/32Go PX5 but 8" screen
-SilverStrong PX5 8" 4/32Go with DSP , is DSP a good value ?
Thank you for your help.

After some reading online I choosed Eunavi-WG9018S model, you can find it on AliExpress.
I'm using it for almost a month now and it's plug and play with integrated canbus which works very good - a lot of car system information displayed + steering wheel controls and OEM parking sensors.
GPS is very accurate, I left the antenna in the dashboard behind the unit and no problem with the signal.
Audio is OK, I used mostly with Spotify and the sound is OK. Being Android we have a lot of option in matter of players and equilazers.
PS: I own an Passat B7, but both your and mine are VAG cars so the wiring is similar.

Hi,
On sunday i installed on my Octavia 2 an Isudar NA02A53VW0907 (PX5 4/43GB 9'' ) on Aliexpress store (11/11 Sale).
previously i own an Ownice C200, until this summer when the unit stop working, some overheat problem..
Base only on experience of these days, it's miles better than Ownice..
I need to find some calibration for colour, it's washed..

Hello,
I join your thread for my Skoda Yeti 2015.
@ludz179: did you find a head unit?
@aurelv: I'm interested by your Eunavi-WG9018S model. Did you confirm that all is working fine (OEM reverse sensor, steering wheel controls...)?
I have some other questions:
- did you know if FastBoot is supported?
- I don't see if SDcard slot is on front?
- what do you think about the quality of the screen (reflection, brightness ...)?
- how does it fit into the dashboard? Would you have a picture?
- do you face particular problems (bug, overheating, crash, reboot)?
Did you confirm that you have not added anything in the connectivity between the original socket and the one provided with the Eunavi?
I have this socket:

Car builtin display shows "mute" on audio menu after installing Android Unit.

Car builtin display shows "mute" on audio menu after installing Android Unit.
I installed this radio, it works, steering wheel buttons work. Only thing is the display audio menu in the car shows "mute" regardless of what channel is in (FM1, FM2, DVD, AUX etc). The radio is not mute. The canbus decoder is connected. Any idea?

I had something similar a few days ago.
In my Joying I have with the steering wheel buttons in third party apps problem. Then I have to test the CAN BUS adapter infected by the Old Joying radio. After a After a restart I also had Audio Mute. However, the buttons and knobs on the radio were no longer synonymous.
In the radio app, I could not select a station.
Then I exchanged the CAN BUS adapter again and then it ran well.

Sorry but I don't think I understand what you are saying. Do you have a mercedes benz with cluster display that was showing mute or what? Also, you changed the can bus, you mean the canbus decoder or a setting in the radio? My unit doesn't have access to factory settings menu.

I have a VW and there I exchanged the canbus adapter. After that, I had the problem that I no longer had an audio output. Mute was displayed on the car radio with me.

Help with Chinese Android Headunit XY Auto 8227L (audio problem)

Hey guys,
I've recently bought a 2nd hand car from a private sale, Honda Accord Euro R 2007 which came with those android headunit thing from aliexpress which I've seen few on this website.
However my problem is that when bluetooth is connected, the connection is fine (I can use the headunit to change songs etc) however there is no audio produced from the car speakers when playing through bluetooth.
I can play the radio and sound will come out fine but whenever I try to play something through bluetooth no audio is played, previous owner said when he had it installed from a specialist they couldn't get it working either so was wondering if you guys had any suggestions.
Also i don't know if this is the case for you guys as well but the volume for the radio (the only thing that makes sound currently) when it goes from 0 to 1 it's extremely loud, like it's not a subtle change from no sound to little sound, it just goes from no volume to Very loud as the first option.. is there some firmware update that can fix this problem as well as the bluetooth issue that I am having? Maybe you guys think it's the wiring at the back?
Specs for my headunit are below:
Android: YT9216C_AHD_00005_V004_20190522_HIFI
System: Android 8.1 Go
Kenel: 3.18.22
CAN Pro: Daojun-Accord7 Single-V4.7.2-connect
DDR: 1G
Flash: 16GB
CPU: A7 1.3Ghz x 4
Capacitance: 10000 uF
Display: 1024*600
MCU1: HW8227L-3.3-SW0-3.0
I've also attached photos of the above. Any suggestions or comments will be very helpful as I honestly don't know what to do and before I replace it I would like to try get it working if possible.
Thank you for your time!

If you have an external amp, the blue antenna wire is probably used to turn on the amp. This only has power when using the radio app. You must change the wire over to the red ACC wire so the amp is turned on when the car is started. I had to do this on mine today.

My 8227L unit had an antenna wire with about 10V when the radio app was running... But it also had an amp wire that could be enabled somewhere in settings (amp=on) I think it was in factory settings but I can't really remember.
TboneL's suggested fix should also work just fine.

This would be awsome if I could do that in mine. I have a Peugeot 407 SW with the 8227L Android, and no sound plays whatsoever. As I've read, I need to connect the AMP-C wire coming from the car connector to the ACC red wire. Or if it has a way to achieve this through software, would be great. I searched everywhere in the options but can't find it.

Assistance Figuring out information on this Head Unit

Hello! I just recently installed this headunit on my bmw, I have browsed this forum for a few hours just trying to figure out more information on it, I have found myself in a never ending loop, The roms, mcu's, etc. I am utterly lost on trying to figure out more. It works great! and I love it so far, I managed to update the MCU Version the other day, not sure if that is able to tell anyone anything either, The one I had installed was: "Ksw-Q-Userdebug_OS_v3.6.5-ota" I at least think that is an MCU version, regardless I had installed it and it worked well, updated ZLINK and also seemed to help the bluetooth a good bit, I'm now able to connect effortlessly, and immediately launches Carplay and its near flawless minus the slight 1-2 Second lag (As expected for bluetooth) I am curious to see what all you guys can talk me through so I can either better understand my headunit or even show me. Id love to learn about a few roms people have been using and what exactly the benefits are to the one I am using, A popular thing brought up is "Rooting" What benefits would rooting my headunit bring? If there is any. And also I am having issues trying to connect bluetooth to my obd reader, I am able to actively pair it (Enter the pincode) and after that, it refuses to connect regardless how many times I press connect, it seems to just not do anything, I am attempting to use it to monitor AFR, Boost, EGT's Oil pressure/Temp, etc through bm3 I had even went and bought a enet to usb adapter and tried plugging it into my headunit obd port but alas, It was not working regardless, It isn't able to read vehicle vin information etc. Absolutely ANY information regarding my system either capabilities, Roms I should try, what exactly an MCU is, etc is appreciated. Below I have attached my Unit link on amazon, aswell as system information. Thank you! Zack

Not MTCD, requested moderator move to (Android head-units) forum.
Op try searching forums with MCU suffix and using punctuation, and new lines.
This headunit looks to be an oddball. Good luck.
