Hi Guys
I have a Android head unit :
Firmware : YT9216BJ_00012_V001
Android : 9.1 Car edition
XY Auto 6.2(x2)
CPU : A7 1.3 Ghz x 4
1GB Ram , 16 GB Rom
MCU 3.5 (X2)
Here is the problem I have
The sound settings seem to be different for the FM Radio and Bluetooth, than for the music streaming from the head unit itself playing from YTMusic and Spotify.
I have a external 4 Channel amp set up and running 2 from the L+R outputs, and 2 from the sub out
The FM radio and Bluetooth will be set up and if I use the apps installed on the HU, it is a lot softer, and it seams like the sub channel is affected the worse, It sounds like there is a frequency cut, like anything under 50 HZ is chopped.
I can set the levels in the volume settings, but as soon as I go to the FM Radio, the bass is about to blow the sub.
Please let me know if you require further information
As for the rest of the unit, I am very happy, just want to get this issue sorted, and perhaps a better offline map app.
Thanks

Hi,
I have this unit installed , i bought it because in my car there a not many options with a bigger 9" screen. all the other options will give that 7 inch layout and buttons.
I got steering wheel buttons, so dont need any on the display

Bway 9 Inch Headunit
Model Name: BW-90910
OS Android 6.0.1
CPU:Intel ATOM X86 Quad-core 1.2 GHZ Sofia 3GR
RAM 1GB DDR3
?ROM 16 GB
Resolution 1024*600.Capacitive Touch Screen
Built in Sygic map
Solution Sofia
Sound processor TDA7388
Build Number : Sofia3gr_car_64-userdebug 6.0.1 MMB29M Eng_build_20170815_121351 release keys
car : Ford s-max 2008
I have 3 issues with it
1 : The audio randomly mutes while driving, sometimes it doenst happen at all. sometimes 3 times a hour.
The sound goes into mute mode, you see the sound icon crossed out. Then i press + on my steering wheel and it goes back to the previous audio level.
2. Its kind of laggy when i use TomTom Go and Spotify, can i upgrade the memory? Gba soldering solutions is doable by me, just need to know if its still worth doing.
3. Audio quality is poor. i am missing the rich volume. i read about the amp replacement. but that will not work for me, i have a amp build in the car.
4. cant connect any other bluetooth devices
i replaced the stock speakers from the car already with new ones. but it barely became better.
Questions :
1. can i upgrade the memory?
2. There are no updates from Bway, Can i flash android 7 and remove all the crap from this build, and get better equalise support and bluetooth? and maybe fix the muting issue.
3. i am also looking into this newly listed model
https://www.aliexpress.com/item/-/32853040455.html
This has 32gb and 2GB and a octacore and higher clock.
would i benefit from this model?
thanks!
Hello guys!
So, I have a 2005 Audi A4 B7 and I'm thinking about buying an android head unit for my car. So far I have found 2 head units that look somewhat like the factory one, or that I like. They both have Android 8.0 / 8.1, Quad-Core with 2GB of RAM. Now, are these chinese head units generally worth it? I'm really concerned about sound quality (I have an aftermarket amplifier and subwoofer installed). Now I have a Kenwood head unit and the sound output is decent, can't really complain (better than factory radio).
And I have a few questions.
One of the units is made by Mekede (the factory look-alike) and the other one is made by Wondefoo. Has anyone had any previous experience with these 2 makers?
Also, I do not see an AUX IN on these chinese head units. Do the have one? Is it possible to have one? I'd much rather play music over BT, but is generally the connection stable?
Seeing as they are Android, am I able to install 3rd party apps, such as Vanced YouTube ? Or Waze (or any other app that does not come preinstalled) ?
Generally speaking, how is the boot up time on these units?
They both cost around $210. Are they too cheap? Should I try and save up more? Look for other makers? Most of the times I'm going to be listening to music (either via USB, BT - or any way it can be connected to my phone; or YT) while, sometimes, using Google Maps / Waze. Are these cheap android head units generally laggy when multi-tasking? Does it really matter which one I buy, as they're all "cheap chinese products"?
Here are the links to the units:
1. Mekede
2.Wondefoo
Or if you guys could recommend me another one which really is worth the money, it'd be appreciated. I'd like it to have volume knobs, and the factory look-alike is a plus.
I am sorry if these questios have been asked before!
Thank you!
One thing to keep in mind - RAM amount. 1GB of RAM is not enough for these units. I'd recommend 4GB of RAM, but make sure you get at least 2GB of RAM for sure (and even that may not be enough).
Try to find a unit with PX5 (octa-core) or PX6 processor and 4GB of RAM, if possible. Android 8.0 or 8.1.
In terms of sound quality, I too was concerned. I ended up rooting and installing Viper4Android and the sound quality is great. I'm using an extenral amp, but the internal amp sounded good with V4A as well. Viper4Android gives you a LOT of flexibility in customizing the sound to your liking.

Must be a PX5 or PX6 ? Most of the sellers don't list their processor model, just listing it as "octa-core". I'm aware that V4A can give you a lot of flexibility in sound customization (I've used it on my phone for a while)
Do these head units integrate well with the CAN ?
Here are the more technical names (may help identify them):
PX3: Cortex A9 (Quad-core) - 32-bit ARMv7 architecture.
PX5: Cortex A53*(Octacore) - 64-bit*ARMv8 architecture.
PX6: Cortex A72 (I'm not sure of the details - brand new platform)
From what I've seen, most Android 8.0 units are PX5 and most Android 8.1 units are PX6 (brand new). Units with older versions of Android are probably PX3, I'm assuming. Most of these units do not get "official" major Android version updates - the manufactureres just release new models instead of upgrading existing models (but some can be upgraded via custom ROM's).
Personally, I would probably look for a PX5 MTCE octa-core unit with 4GB of RAM. I wouldn't consider anything older than a PX5/Android 8.0 unit - and like I said, I'd recommend 4GB of RAM if you can find it. The PX6 units are brand new - there are no custom ROM's or anything for them yet or anything. They also seem to come with less RAM and storage from what I've seen?!?!
Only way to be 100% sure what you are getting is to ask the seller - they should be able to tell you the processor type and "MCU" type (MTCE-XXX),where XXX is the MCU type. The MCU is like the "go between" between the Andorid OS and the radio hardware (MCU type can be seen under the Android settings menu) - you may even ask them to send a screenshot of the hardware info from the Android settings to confirm what it actually is.
Just a "general" overview of some of the basics - I hope that helps.
Oh - and if you have a CANBUS car, you need a CANBUS adapter. If the seller is selling a unit specifically for your car, they usually include the CANBUS adapter. That will allow your steering wheel controls to keep working and other items.
Yes. That actually helped. These with 4 GB RAM and at least a PX5 cost more, about $350 so I'm going to wait, save up a bit more, because I also need to convert my car from 1 DIN to 2DIN and that will cost me at least an extra $70.
I also want one that looks like the factory equipped one, so, yeah, I'll just wait another month or so.
Thank you for your answers, guys!

I have a mekede unit supposed to be android 8.1..... It's not it's actually 6.0
This was from mekede official store on aliexpress
They are now not answering my messages and unfortunately I didn't figure this out until after the buyer protection time limit had ended.
Just to post an update to my original post... At first, I thought that the sound quality was great. But the more and more I used the head-unit, I found that sound quality was NOT up to par with my previous WinCE head-units. And I also ran into noise-related issues. I did everything in my power to try and resolve these issues (including using external amps for better sound quality), but in the end, I gave up and re-installed my WinCE head-unit.
Unfortunately, from my experience, these Android head-units just aren't up to par in terms of sound-quality and noise-rejection. I had noise-related issues from the LED backlighting, USB devices, wifi and bluetooth wasn't very good either. Hopefully, they continue to improve upon these units, because having the head-unit run a full version of Android is great - but sound quality is also important - and even more important to some (like me). Would be great if the big audio companies starting building full Android head-units (Pioneer, Kenwood, Alpine, JVC, etc).
Since my WinCE unit supports Easy Connect, I can still get the advantages of Andoid for certain things while also having fantastic sound-quality and no noise issues. Best of both worlds. Granted, the WinCE unit is significantly more expensive ($699 vs $350), but just like anything else - in most cases, "you get what you pay for". The WinCE unit that I'm talking about specifically is the Dynavin N7 - and they use high-qaulity sound components. But I also had Rosen WinCE head-units and they sounded great as well (but again, significantly more expensive).
All depends on what is most important to you - software flexibility or sound quality.
My new 2021 PX6 from Phoenix Automotive Vertical Fast Boot OEM fiber option. Had this for about 2 months. I use it with an external OEM AMP. Used in a Lexus.
AMP is not fiber. The unit is a PX6 MCU RL78c (2014 Chip-set) NCHHWY V332-0 , Framework px6-userdebug 9 PQ2A 190305.002. OS 9.
Audio is very good! I love the sound. Speakers: OEM Mark Levnson in the front, 6.5inch JBL GX600C + Sound Ordnance M2-10DVC 10inch in the back.
Tested only with stock HU.
What works on the stock PX6:
(With correct wiring harness)
1. Fast-Boot. After first 2 setup boot-ups, on is instant for 24 hours of nonusage.
2. AC controls work (Cooling).
3. Searing Wheel controls work out of the box on Lexus w/canbus included.
4. Audio player works but not a good GUI.
5. Phone works with Bluetooth.
6. Android Auto is installed and works.
7. DSP Sound works with an EQ and many settings, GUI is good.
8. Most User Settings seem to work. Wheel mapping may stop after Fast-Boot for 5 minutes (bug).
9. Navigation (Google Maps) works, GPS works.
9.5. Maps works Off-Line in Google Maps.
10. Radio with about 16 memory storage.
What is not working in a Lexus / Toyota :
1. Factory Settings. All-access is denied. Locked out! Big Issue for me.
2. GAS monitor/usage. This should work out of the box. Phoenix says it is not working and is disabled in Lexus. BUT is advertised to work on the Phoenix site.
3. Sound MAX loud setting will NOT save after reboots. After boot, the sound is all the way up, loud. After talking with Phoenix tech, no fix. However, if FastBoot is on, the audio may save to a lower setting for about 24hours. If you don't use HU for 24 hours settings are lost again..
4. Screen will reflect windshield in GS Gen3 Lexus. May be an issue in sunlight.
5. If you wear Sunglasses or have glasses that do auto shade to dark, you may not like the screen because it can be hard to see.
6. Radio- Local / Distance not working. Can't find a fix. However Local radio is working fine. I get most local stations clear.
7. Temp display worked for 2 days now showing -40 at all times. (No fix).
8. Fast-Boot image changing. The stock app that changes the BOOT-Image will not work. It is out of date and will not work with Android 9+. It needs an update from Manufacture. A Phoenix Auto add-on app (download), also will not work, out of date. App complains of an Error with the Android version.
Add-On that work:
1. Musicolet from Play Store. The Stock Audio player sucks big time.
2. Bluedriver OBD2 reader.
3. Torque Lite or Pro OBD2 reader.
4. Function Generator, from Play Store.
That's about it.

Hi guys,
I have a Chinese Android headunit with the 8227L_Demo chip and the fader-balance is not working. I have the option but when I move the dot around the car image, the sound still plays on all 4 speakers. Also, the EQ settings doesn't seems to change anything. The other bug I have is there a big gap/jump in the volume between 17 and 18 and the sound mute for half a second when I switch from 17 to 18 and vice versa.
Anyone experienced something like that ?
As I can't upload any image here I write all the info of my headunit.
Android: YT9213AJ_00011_V001_20200330
Android OS: 9.1
XY AUTO: 3.2 (8227L)
CAN PRO: 3.1 (8227L)
DDR: 1G
FLASH: 16G
CPU: A7 1.3Ghz x 4
Display: 1024*600
MCU: 3.1 (8227L)
me too, same problem. my unit is Blaupunkt key largo 970 but CPU-Z and some other in system hidden settings confirm that this unit is alps_ 8227L_Demo.
can you share your Equalizer.apk app?
plz help me i cant use sound fader , the sound too loud behind me and it disturbing mz
Hello Guys, I don't have any solution, but I have the same issue. Fader doesnt work. As far as I know, this is not because of the HU but the Harness. I have a JBL System and I had to buy an extra harness which doesnt allow me to use FADER.
My 2 cents.

can you show us picture please
I'm afraid guys, there is no solution. The reason it doesn't work is that your unit does not have a dedicated audio chip. Older units all had it, like YT9216, YT9217, YT9218, and even (older) YT9213AJ. If you buy Android 8.x or 9.x then the audio chip will be present.
See the pictures below explaining the issue.
The audio chip is TDA7729 (TDA7719 , CSC37033 , SCS37534).
Now there is a fix but it requires advanced soldering skills and a proper setup.
Sorry to be the bearer of bad news.
Hello, after many month of thinking what to put in my car, I decided not to risk with ones straight from china , even though they have a great design , their prices went quite up. So I bought one from my country which again is Chinese but has 2 years warranty. It has the following specs: Android 11 - octa-core CPU, 4 GB RAM, 64GB ROM, RDS, DSP, CARPLAY . A decent launcher design. After I had it put in my car there are some problems of course...
First of all my dashboard became Chinese , secondly the steering wheel controls don't work. I searched for information and found that I can go in factory settings and change the can bus software or something. I found out I can get in these settings with the password 3368 . And there are many types of CAN BUS settings. Around 5-6 have Opel Insignia . So far I tried 3 and it doesn't work - it doesn't prompt me to reboot but I do it anyway. Also in the navigation "car settings" it just seems like it doesn't talk with the car at all. At least I got to put the Opel logo for boot up animation.
Climate control works from the old knobs , and does not visualize on the screen - this is not really a problem for me but still wonder why doesn't it work. Also i got a OBD II dongle which lights up when i plug it in and the navi Bluetooth finds it , but i cant connect to it - it wants a passcode and 0000,8888,3368 don't work .
Now for what DOES work - the new rearview camera starts when I put it in reverse , but the lines don't bend. Music comes out of the speakers . Blinkers and hazards and chimes have e new bad sounding beep , but at least there is some communication with the car. Sport and Tour buttons work ! The mechanics which put in the new unit took out the whole cd changer , I don't know why and if it was necessary and if it is a problem. Park assist also work and the button but it also has changed chime sounds.
When i contacted the sellers they told me they just sell, and don't know much about installations.. they told me its model is just "8581" not really helpful like the Chinese supports which i expected to avoid.
Any help will be greatly appreciated !! Mainly i want to fix my dashboard to be in English again(when the battery disconnects and the computer resets , it usually goes back in German, never Chinese) And the other thing is to get the steering wheel buttons to work and along with it to have more communication between the car and the navigation unit.
Try reading forums and posting what has been tried, or at least try to figure out what the unit is

I found those. But it helps me in no way.
The problem was a wrong connection on one of the many cables . Now everything works , and im quite happy with the unit. I dont know in what standby mode it stays but it boots up for seconds, another 5 seconds for the wireless car play and the music starts automatically from Spotify and the maps are ready to navigate. My car leveled up

Hi all, I have same problem can anyone help at all. Thanks in advance
Recently bought an 8227L headunit running android 11 and randomly after turning on, apple car play has no audio. Restarting the head unit usually resolves this issue but I shouldn’t have to.
Today, the audio wasn’t working so I tried going to the native radio app and it would play sound, but was very low. Going back to apple car play, the audio would play but also sounded very low. Setting the audio to max (40) sounded like it was at 15. Again, restarting resolved the issue.
Is there some setting or workaround for this ? Any help is appreciated. I’ll post the headunit specs below.
2gb ram
Android 11

What does seller suggest when contacted for support?
