Hello, very good, I updated to version K4811_NWD_S217206.20230928.142356.H5D9.01F a few days ago but it turns out that in the system settings it does not give me the option to set it to Spanish, all the other languages appear except that one, if you can help me, greetings for all.
[Android Head-Units] axelrend:
sorry what settings??? if you talk about the secret menu (16176699) it remains in English even if you set other languages, just change a ''general setting'' in your linguage
[Android Head-Units] axelrend:
here a boot logo for you , just create a new folder : new_boot_logo on usb pen drive put in the logo , put the usb on radio and copy from your usb into the radio memory sd the carpet a name : new_boot_logo , join to the secret menu 16176699 section boot logo and you see your logo choise and save waith a rebot and your logo apear
[Android Head-Units] Fermarsal41:
Axelrend, thank you for responding, it is in "general settings" where the option to change it to my language does not appear, thank you.
[Android Head-Units] axelrend:
you change the language from the classic Android menu, if you lower the top bar where you have the clock, the wifi icon etc etc you will have the Android settings wheel, the classic menu, date and time, language, keyboard, characters, android version, krnel, etc etc etc etc if I remember correctly, setting your language should also change the menu ''general setting''

Has anyone found a LOUDNESS setting in version 20230928?

Hello, I searched all the listings and I didn't find my car, which is the Mitsubishi lancer why is this happening?

Hi Guys, I'm new here. looking update for my radio 6/128 FOR CHEVROLET CRUZE APPVER: K4811_HDKJ_S217151.20230603.142747.H509.01D

but no find : Can you help me please ?
[Android Head-Units] KoTiX2:
On telegram Russian group somebody posted this new firmware:

K4811_OH_S217101-20231030.zip

OH version seem to be compatible with NWD and one guy already flashed it over an NWD. Everytime seem to work ok:

And a Chinese guy made a rooted version of it:

K4811_OH_S217101-20231030_magisk.zip

Anybody brave enough to test them?

I won't be responsable for any bricked device. I'm just posting what I found.
[Android Head-Units] axelrend:
It seems like a different model from the 9-inch Chinese ones, this one has physical buttons underneath, ours only has touch buttons on the inside side of the radio, I don't think it works
[Android Head-Units] Barykelo:
The OH version is fully compatible with NWD.
[Android Head-Units] peecee55:
When you say compatible are they basically the same. Or any different improvements either way. Sorry not up with differences between these units.
[Android Head-Units] KoTiX2:
The phisical buttons doesn't matter with the firmware, they can be configured in factory settings.
[Android Head-Units] Valantino:
name of navi insta group ?

Can you help me ?
[Android Head-Units] Barykelo:
Ruancheng has already sent me this update as well.
[Android Head-Units] KoTiX2:
Nevermind, I flashed them by my self and everything was fine (no bricks).

I haven't tested the firmware, I cannot report if it's good or not. I can only say that it's safe to flash.

All I need is root access to so my experiments ;)
[Android Head-Units] axelrend:
Se hai tempo fai qualche foto così possiamo vederlo, grazie
[Android Head-Units] Barykelo:
Please share the rooted version from another repository. Thank you

In my Multimedia there was K4811_JYT so I put this version K4811_OH_S217101-20230923 and it is running perfectly. I will download this version to evaluate.
[Android Head-Units] FeRn4nDOsb:
Guys please let me know if these firmwares are compatible with different resolutions, because K4811 has many kinds of screen, in my case is 1920x1200
[Android Head-Units] laurent.basset@neuf.fr:
Do you have tested this version K4811_OH_S217101-20231030.zip ? Ruancheng send me the 20230923 version ! thank you
[Android Head-Units] Hamman82:
Good morning.

I am new here.

I have a few questions about the K4811 (2000x1200P, 8/256GB):

1. how to switch the built-in microphone to external ?

2. how to activate the vol+ vol- buttons on the left side of the display ?

3. why when listening to the radio, the waves often escape and the radio hums ?
[Android Head-Units] axelrend:
1 swithc auto wen you inserit a external microphone

2 check video

3 on menu main put your region and put on RDS (rds in secret menu 16176699)
[Android Head-Units] Barykelo:
Don't know how I get something else into this window? Does it even work?
[Android Head-Units] Hamman82:
U mnie pokazuje prędkość o 30km niższą niż na prędkościomierzu i też nie wiem dlaczego?

Ale chętnie też zamienię go na coś innego.

Mod Edit: English Translation Below

For me it shows the speed 30 km lower than on the speedometer and I don't know why?

But I would also like to exchange it for something else.
[Android Head-Units] Barykelo:
It shows me approximately 5km/h less. This is because it is from GPS.
[Android Head-Units] BartmanEH:
well @m00n61, your unit looks significantly more functional and customizable than mine. I can only hope the cooling fan in my unit is temperature controlled—as it is having installed it in winter time here, the fan has never come on, although I have turned on the “external amp“ feature and connected externally with it’s cheesy wires poking out the back of the unit—there is no adjustment of fan turn on temperature that I can find (although I haven’t tried the full factory settings pw 16176699 yet).

Posting a screen shot of AIDA64 here for reference:
[Android Head-Units] m00n61:
In my unit there's a FAN app where one can choose to have the fan controlled either manually or automatically by the CPU temperature. The CPU temperature is user-adjustable.

Screen size apart our units are the same.
[Android Head-Units] BartmanEH:
I wonder if @m00n61 wouldn't mind trying to extract that fan app so I can try it on my device. You seem pretty knowledgeable but just in case, here's how to extract an APK:

Here you are. Enjoy!
[Android Head-Units] DanKama:
I just bought a similar HU last week but with 2G RAM and 32G capacity.

I installed it myself c/w rear camera.

Unfortunately, the parking brake warning light comes on and the annoying beep sound also comes on when the car is moving, even if the handbrake is disengaged.

Based on earlier comments here, I'm glad that I've bought a reasonably decent HU.

Hopefully I can explore its potential once I've resolved the warning issue.
[Android Head-Units] BartmanEH:
It’ll be a few weeks before I have access to the unit again to try this. Many thanks for your efforts!
[Android Head-Units] BartmanEH:
I have to say, I don’t see how this is related to your installation at all. Probably just a coincidence. I bet if you disconnect your new head unit entirely, you’d still have this issue.
[Android Head-Units] Jogor:
I have the same unit, but I didn't get Zlink on it, possible to extract the APK for me?

After installation my steerwheel buttons won't work, but It's probably because I can't find my car (Opel Mokka) in the Can type settings.

My OSD is in Chinese too, can't find where to change it..

What build number are your device?
[Android Head-Units] m00n61:
See my build number in attach.

Unfortunately Zlink APK seems too big to upload here. But you can download it from this site.
[Android Head-Units] Jogor:
Looks like we have exactly same build.

Yesterday I got a new Canver from the seller with newer Canver and I think Zlink was included too.

So now my steering wheel controllers working and also Android Auto.

So I went from being slightly dissapointed to really happy with my device.

In the factory settings I can change Style, but it never saves, it just goes back to UI Style 1, is it same for you?

I have attached the file I got, but no need to use it if your Can bus is working
[Android Head-Units] m00n61:
I still struggle to find a CAN BUS decoder for my Suzuki Vitara so for now I'm good, my SW controls are analogic. Anyway, you should be able to update to newer versions from MyCar app. My seller told me a newer version of the firmware is to be expected after the Chinese New Year festival,so sometime in February.

As for style switching, the Style in factory settings should allow for launcher switch. But, for now, only one launcher is available and this one changes styles with the Styles app.

I hope that with the new version radio stations will stay saved after restart.
[Android Head-Units] Jogor:
Saved radio stations and a way to change launcher would be really nice.

But now I got Android Auto working with BT, so I just hit Zlink button and AA start with Tune In as radio from my phone, so I'm very happy with that.

Please keep us informed if anyone get new versions or anything else that others could need.
[Android Head-Units] halloj:
Do you have a link to where to buy the same HU? Thanks
[Android Head-Units] m00n61:
This is where I bought it.

It is also sold here

Ainavi also sells a similar unit that has more customization options, including different processors, see here
[Android Head-Units] Jogor:
I bought mine from Jmance store on AliExpress. But even if I'm happy with mine HU, I think I would buy a Junsun v1 pro instead if I bought one now.

Looks the same but bigger community and looks like better software.
[Android Head-Units] m00n61:
That Junsun unit looks like a 10 inch UIS 7862, probably FYT. This is the kind of unit I switched from. The only positive thing I can say is that it does have a large community and you can already find modified firmware. Understandable, this model has been around for more than a year.

As for the software, I can't say it's better in any way, I used a similar unit for about a year and a half.

P.S. After taking a look at the UIS7862 thread on 4PDA I would definitely stay away from Junsun.
[Android Head-Units] maids:
I am trying to find an update or apk for my unit as waze is on a split screen and its tiny
[Android Head-Units] m00n61:
Did you try to update online? From Mycar app.
[Android Head-Units] maids:
no do you have a link
[Android Head-Units] m00n61:
MyCar is a factory app, should be present in your unit. Go to the Upgrade tab and press Check

Hello everyone

I have a k4811 nwd, when I installed the screen firmware update_LCDTYPE84_M_KL_jd9365 from the 4pda forum, the screen went gray, you can solve it now but now the carsetting doesn't work every time I enter it restarts, do you have a solution?
[Android Head-Units] peecee55:
Check in factory settings pwd 16176699 to see if 360 camera is enabled. If so remove tick and save.

Hi. Has anyone tried the K4811_OH_S217101-20231030 firmware? Is it working properly?
[Android Head-Units] axelrend:
This firmware works great, it was sent to me by the seller installed and it works well (K4811_OH_S217101-20230923) insert update.zip on pen drive, extract update script from archive and insert together with update.zip on pen drive restart the radio, the installation starts on its own (or it should), at the end remove the pen drive or I will start a new installation

[Android Head-Units] EDCORHU:
I have compressed the video, I hope it can be viewed. The fault was that I used an LCD driver that does not correspond to my radio which put it on a gray screen, I found a way to solve it but every time I opened carsetting the radio restarted.

Were anybody here able to use adb on these units? USB or wifi ?
[Android Head-Units] sunujacob:
Wi-fi will work. Use adb app control
[Android Head-Units] KoTiX2:
I cannot get it to work.

Does it work for you?
[Android Head-Units] sunujacob:
Procedure of actions:

1. Connect the head unit to the same WiFi network to which the PC from which we will work is connected.

2. Find out the IP address received by the HU

3.Enable developer options.

To Use ADB First You Have Enable USB Debugging In The Developer Options In Your Android Phone.

Pull = Taking (OR) Copying Files From System(Android)

Push = Copying/Replacing the Files To The System

Connect through Wi-Fi:

1. Connect the Android device to the same WiFi network to which the PC from which we will work is connected.

2. Find out the IP address received by the Android device.

3. Enable Developer Options in Settings.

5. Enable "USB debugging"

6. On the PC, run the following commands sequentially*:

adb connect 192.168.1.37:5555 (As received by your HU. 37 is example)

(in response we should see: connected to 192.168.1.37:5555)

adb root

adb connect 192.168.1.37:5555

You Have To Mount The System

adb remount

How To Pull Files:

adb pull /cache/update.zip (adb pull system/cache/update.zip)

adb pull /system/priv-app/Settings/Settings.apk

You Got Your File from the System!

How To Push files

adb connect 192.168.1.37:5555

(in response we should see: connected to 192.168.1.37:5555)

adb root

adb connect 192.168.1.37:5555

You Have To Mount The System

adb remount

Put Your File In The ADB Folder as shown in command prompt (Eg. C:\Users\Sunu\strings.xml)

adb push strings.xml /nwdappconfig/app/international/com.nwd.audioset/values/strings.xml

adb push eqcustomer.ini /nwdappconfig/app/eq_force/eqcustomer.ini

adb push rock /nwdappconfig/app/eq/rock

adb push gps.conf /system/etc/gps.conf

adb push gps.conf /system/etc/aw3603D/config/PlatformConfig.json

You Have Pushed/replaced the Files.
[Android Head-Units] KoTiX2:
Thx but i perfectly know how to use adb and what it's used for...

I asked you if you were able to use it on your unit becasue I can connect all my other 6 models (MTC, FYT, QF01 etc..) using wif adb or even USB but i cannot connect to my PC with this k4811 unit.

the response is always error 10061

Hi. I have a problem, Bluetooth and Wi-Fi stopped working on my radio. The update did not help, could it be a damaged radio?
[Android Head-Units] Barykelo:
Try looking in the factory settings, if you have BT checked in the first Feature Setting item. I don't know if there is Wi-Fi, I'm not in the car.
[Android Head-Units] axelrend:
check video in this menu you can find wifi and bluetooth
[Android Head-Units] RademenesDania:
I have it running on factory settings. This is a more serious problem. Wi-Fi, Bluetooth and 4-pin USB connector do not work. At first it happened sporadically, but now it has stopped completely. Disconnecting the radio from the power supply also did not help.
[Android Head-Units] Barykelo:
what about a factory reset?
[Android Head-Units] RademenesDania:
Tomorrow I will try to restore the factory settings. I wrote to RuanCheng and he is supposed to send me the update file.We'll see if it works. It looks as if the radio has lost modules.

I have been running it on switched power only because I don't want to have to push restart every time start the car.

[Android Head-Units] enzo60:
I tried with ZLINK5 but it only connects with a USB cable and not via WIFI. Same with HUR. In the K4811 I see the writing "in this device it is not possible to connect Android Auto in WIFI"
[Android Head-Units] m00n61:
Did you enable wireless AA in your phone? Do you have an older Xiaomi or OnePlus phone? Both Zlink 5 and HUR work very well. HUR is a little more difficult to set up. Zlink may have difficulties connecting, it is best to reset your BT connection.

I have enabled all functions, WIFI, BT and all permissions. My Xiaomi is the latest generation. And the K4811 which won't let me connect to WIFI. As I said, when connecting, on the K4811 I read that it is not WIFI enabled
[Android Head-Units] peecee55:
You cant have bluetooth tethering on at same time as wifi. I allow bluetooth for everything else as I hotspot wifi internet from phone not from tethering. If you have tethering on HU thinks you want to use that for internet.
[Android Head-Units] enzo60:
Can you tell me the procedure to activate Android Auto with wifi on the K4811, via the Zlink5 application
[Android Head-Units] m00n61:
You cannot connect via WIFI if you have the hotspot active on your phone. You also cannot do it if you have the HU's WiFi client started. For AA WiFi to work the phone must connect to the HU's hotspot, automatically activated by Zlink. You should read how WiFi AA works.
[Android Head-Units] FeRn4nDOsb:
Have you selected carwebguru as default in CarSettings?
[Android Head-Units] Hamman82:
I repeat the question. How to activate the buttons under "MIC" "RST" because I only have these displayed as they are selected.
[Android Head-Units] FeRn4nDOsb:
I'd be glad to know also is how to move this from the right side to the left side, mine is only on the right side to open this menu
[Android Head-Units] Hamman82:
But what I'm concerned with is how to turn on the ones highlighted in red because I can't do it in any way.
[Android Head-Units] peecee55:
Yes I had the same until I changed both Android settings & CWB settings as well. There is a setting to change home button to CWB too.
[Android Head-Units] peecee55:
I don't use Android Auto as I use Google maps & Spotify on the head unit so really have no need at present. I just hotspot internet from phone.
