Previous News
2013.11.16The manufacturer intends to add new features to the unit, they are currently developing an OBD II system, I assume this would be via USB. They say it will require additional hardware.
Sooner than that, they plan to release wireless mirror link for Android phones.
I asked about Bluetooth compatibility, they said my request would be sent to their engineer to include Bluetooth modules. Whether this actually gets included or not, we will have to see.​

Workaround
Resolved​
Updated 2014.01.20Newest issues will be put at the top, solved issues, or issues with workarounds will be moved to the bottom.
Unable to remove applications that are device administrators without factory reset due to security menu being disabled.
Many applications are unable to "see" the MicroSD card, so the choice of music players is limited. The mount point is "mnt/usb/mmcblk1p1".
Despite selecting "Front Speakers Only" for navigation sound, the sound comes out of the rear speakers too. Setting to "Front Right" appears to work correctly.
Bluetooth is restricted to phones only. (Unsure if this is hardware or software related, talking to manufacturer suggests hardware limitation).
Bluetooth dongles do not work.
There is a "pop" from the speakers sometimes when changing applications that control sound, this is extremely obvious if you have a subwoofer installed. It happens when the unit is turned on, and when going from mute, to a volume level.
Screen brightness when buttons illuminated is not user-configurable. This means it may be too bright or dark depending on the conditions. For example, when it is only mildly dark outside, and you have your lights on, the screen is very hard to see.
Workaround: Enable constant illumination from the "Extra Settings" menu by setting the option to "CLOSE", this will set the keys to always illuminate. Then use an application such as Twlight to control the screen brightness based on sunset and sunrise.
Random issue when downloading large applications. The progress will usually get to more than 50%, and then no progress is made.
Workaround: The only fix I have found so far is to stop the download, reboot the unit, start the download, and repeat until download continues. It should download from where you cancelled. This appears to be caused by a limited download cache size.
Steering wheel controls only work with default applications.
Resolved: Open the radio (this does not appear to work with the music app), then hold the back arrow in the bottom right hand corner, the app will close, allowing steering wheel controls to function with other apps.
Most recent default application always opens on boot and continues to play, even if paused. This includes the radio, music, video, and iPod applications.
Resolved: Open the radio (this does not appear to work with the music app), then hold the back arrow in the bottom right hand corner, the app will close, and no default app will open on boot.
USB Debugging is password protected.
Resolved: The password is "[email protected]". Credit to @nikko82
Screenshot feature does not work, when trying to save the screenshot, a save error appears.
Resolved: This is solved in system version 2.6.60.​

FAQ
Can I root this unit?
Please see the "Root" section above.​
HELP! My unit is stuck in a boot-loop!
Place the update files on your MicroSD card (see "Firmware Updates" section). Then turn the unit on whilst holding down the volume knob and home button. This should start the update process.​
Can I use Bluetooth OBD devices with Torque?
Not at the moment, Bluetooth is only for phones and Bluetooth dongles do not work.​
Does it have the full Play Store?
Yes, it has the Play Store and all compatible applications are available for download.​
What is the boot time?
18 seconds to home screen, 22 seconds until music application starts. If you use the radio application rather than the music player, the radio sounds as soon as the unit receives power.​
Where can I buy one?
There are many listings on eBay/AliExpress under the search term "android 4.1 car", some have resistive, and some have capacitive screens. There is also the mention of a faster 1.2GHz dual core, however the unit actually has a 1GHz dual core CPU.​
How good is the radio?
The radio reception seems fine, as does the sound quality.​
Is there a Wiki page?
Yes.

Android doesn't have NTFS support, let alone EFS which is built on top of Microsoft's filesystem, but it's capable of using the same cypher algorithms as EFS (AES, SHA, DES) though. The only thing Android needs to be able to decrypt them during the upgrade process, is the manufacturer's or firmware developer's public key, which I believe is stored among the system root certificates.
This, providing EFS or a compatible file encryption mechanism was used to encrypt those files.

If we think about it, Android isn't even part of the equation reading those files really, just a bootloader or the unit's firmware. So the decription layer would have to be built into the bootloader or the raw firmware (read assembly or whatever)... I highly doubt it would be EFS.
As another observation, all filenames remain the same across the two updates and only one file has changed (and it's name remains the same. There goes the hash/sum/md5 like naming theory)...
Code:
diff android-4.1-2.6.40/ android-4.1-2.6.60/
Binary files android-4.1-2.6.40/8e3513e2-ea4a-11e2-8a0f-000c29ba27c0 and android-4.1-2.6.60/8e3513e2-ea4a-11e2-8a0f-000c29ba27c0 differ

Yes, as you say, it is the only file that changes between the updates, and it is also the largest file so I think we can assume this contains the data we want.
Looking at the third update I have, it seems that file is again the only one changed. I will be testing this update out and uploading it shortly.
The file names must have some importance, as otherwise they could just call them "system.img", or something simple, but still encrypt them.

The default application yes, although I did not try what happens with multiple USB drives. The doubleTwist music player was unable to read a USB memory stick, or the MicroSD card. The actual unit seems to be able to cope with multiple memory sticks, I have tried three, and all were accessible using the ES File Explorer application.
The internal storage is mounted at "mnt/sdcard".
The MicroSD card is mounted at "mnt/usb/mmcblk1p1".
USB memory sticks are mounted at "mnt/usb/sda1", "mnt/usb/sdb1" etc.

You might want to try a few different players to see if it's the unit or the player...
From http://www.doubletwist.com/help/question/how-do-i-switch-from-internal-storage-to-sd-card/
We recommend only using one volume to store your media. If you choose the memory card, please do not store media files on the internal storage location.
Also, there is not standardized way of implementing SD card support so each manufacturer implements SD card supportly differently. This is why doubleTwist may not always support the SD card on your device.
Devices reported by users to not work includes the following devices:
LG Motion 4G

I don't know if you can without root but you should be able to as normal user in a virtual terminal link /mnt/sdcard to /sdcard
Code:
ln -s /mnt/sdcard /sdcard
... Something to try. I think it won't survive reboot, but if it works you can possibly make a script for it to happen on boot.

It depends on the player.
All file explorer applications such as ES File Explorer, and Astro, have no issues seeing the files. In fact, if you choose an MP3 file and select the player of your choice to open the file, it will indeed open and play, however it does not show up in the list of available songs.
One example of a player than can see the files is Poweramp.
"/mnt/sdcard" is already linked to "/sdcard", but this is the internal USB storage, not external. Perhaps it can be unlinked, and the MicroSD card, "mnt/usb/mmcblk1p1" linked there instead.

Peter's listing on eBay mentions the headunit supports wireless keyboards, which are bluetooth devices. Also, being it Android 4.1, it should support USB OBD2 scanners like this one on Amazon:
http://www.amazon.com/OBDLink-OBD-II-Interface-Adapter-425101/dp/B002M07XHO
This one is pretty expensive compared to the bluetooth ones, but I've seen it used by dealers to diagnose their cars during repairs.

Best to keep discussion for the 4.1 unit in this thread now.
My keyboard is not Bluetooth, it has a small receiver that is probably 2.4GHz, and it works fine.
Unfortunately there is no Bluetooth menu on the device. However, there are a few interesting quirks with the unit, one being that the security menu is disabled, however, if you try to enable something (I forget what, maybe storing location data or something), it tells you that a lock code must be set, so you press okay, and what opens? The security menu...
I will try installing Torque at some point, as on my phone it requests to turn on Bluetooth, so maybe it will access the menu on the unit. I don't have much hope for this working though.
Perhaps the USB device will work, but I do not have one, and do not intend on buying one at that price.

KEEP IN MIND ALL MY EXPERIENCE IS WITH THE 2.3 OUKU but this might help:
Usb Keyboard is natively supported on all of them, if it's wireless with its own dongle (not bluetooth) that's just all it is, a usb keyboard.
For the bluetooth menu install Quick Bluetooth Lite from Market. I was lucky enough one of the dongles I had lying around worked (one didn't) mine sais "KINIVO" on it.
There is a similar app on the market to use bluetooth keyboards.
...but with both of the above it all depends on the ability to add a BT dongle, the internal one is not visible to android as I understand it (and as it was with the other units OUKU, winCE etc.
I have that exact ODBII reader mainly because I wanted a reliable one that could get the most codes... off topic here, but there is differences. Torque forums are a good resource. I haven't tried USB with it yet. There is cheap usb only out there, but I guess there is two different kinds of usb-to-serial chips... you MIGHT have one of the two installed if they included it....
Bottom line, it doesn't matter what Android supports. What matters is what modules the chinese manufacturer compiled in the kernel or included as a loadable module...
You could get a hint looking at the /home/rick/OUKU/stock/4.1/test/lib/modules/ folder...

Thank you for the advice, I will try it out soon, see what happens.

No, you don't have to buy such devices just for testing purposes. I have plans on buying one for my Santa Fe i45, because USB OBD2 scanners are faster and way more reliable that BT ones, and I'll need it to plug directly into my laptop or the OTG adapter in my SGS4.

Try to plug them when your stereo is turned off. I recall someone saying that you have to plug in WiFi and 3G dongles with the headunit turned off, so they get detected by Android when it boots up. Perhaps this is the case with BT dongles too.

Hmm, I said that. I put it in the main post too. Maybe someone said it about OUKU too, I don't know.
But yes, I do usually turn off the stereo and plug the device in before booting.

Then it must be like sciallo said, kernel has to be compiled with the required modules to make bluetooth dongles work, much like Hal9k's firmware.

Might want to get a terminal for android, like Android Terminal Emulator. Then you can check to see what sort of linux modules/drivers are pre-installed. For example:
Code:

omap3_isp 97716 0 - Live 0xbf014000
omap_hsmmc 14041 0 - Live 0xbf000000
$
This will give you an example of modules installed. In the above example is from the Parrot Asteroid Smart. The output gives you an idea of the sort of devices that you'll be able to use with the unit. For example, there are the cp210x and pl2303 drivers for Serial UART to USB devices. So, for example one could use a USB ODB2 cable as long as they use either a Prolific or Silcon Labs UART.

Something that is not well known is that Torque Pro supports USB ODB2 cables. The product linked earlier from Amazon is an ODB2 scanner by Scantool which is a professional model. (Analagous to buying a Fluke Multimeter vs an Innova) They do have another model that costs a little bit more and supports USB and Bluetooth or even WiFi if you prefer. But, there are some less expensive knock offs that you can get for less a fraction of the price. So, if you know the AN-21 U supports a particular Serial to USB driver then you might be able to use one with Torque Pro. The nice thing about USB ODB2 cables over Bluetooth ones is that the data stream is closer to real time and has less lag than a BT ODB2 adapter around the same price.

Some places hide various menus from the settings control panel, but you can often them bring them up using intents through Activity Manager. However, finding the available intents sometimes requires root but you do not need to be root to execute them. For example:

However, not all Bluetooth software conforms to the Android standards and will force close if it doesn't. In most cases if a Bluetooth driver is installed then a good app to get is Bluetooth Auto-Pair. It allows the manual settings to pair various devices even if the manufacturer implements an artificial limitation on the devices that they will support.

You definitely seem to know your stuff!
That is an extremely informative post, thank you.
I'll take another read tomorrow and do some tests on the unit, see what I can find out.

This is actually a pretty bad blanket statement. It actually depends on the Linux modules included with the Android device. And in fact, I played with an Android TV device that had fuse.ko modules installed and supported NTFS partitions. The best way to tell what sort of filesystem that your Android device supports is through "/proc/filesystems".
Code:
$ cat /proc/filesystems
cat /proc/filesystems
nodev sysfs
nodev rootfs
nodev bdev
nodev proc
nodev cgroup
nodev tmpfs
nodev sockfs
nodev usbfs
nodev pipefs
nodev anon_inodefs
nodev devpts
cramfs
squashfs
nodev ramfs
vfat
msdos
nodev mqueue
nodev mtd_inodefs
nodev oprofilefs
nodev ubifs
$
The first column signifies whether or not the filesystem is currently present on your android device and the second column shows all the various types that it supports.

While you're at it, you might consider installing SRT AppScanner. If the device is vulnerable to Master Key either exploit bug 8219321 and/or 9695860 then there's a good chance that Cydia Impactor can root your device.

I thought you needed to connect your device to a PC to use Cydia Impactor? Also, not sure if it would be required, but USB debugging is password protected.

Well, technically you don't have too. It works off of Android Debug Bridge and can work over WiFi or USB. However, it does need debugging to be enabled. I missed the part that it is password protected. However, the masterkey scripts might still be able to help gain access to root if it hasn't been patched on the device.

The camera was the main reason to contribute. What should I say, the quality ist not really good...
... videos are only in portrait mode & the aspect ratio looks not o.k.

I don't have any charge issues. Just limited functionality. And I haven't had any luck transferring files via Bluetooth. I can link the watch to my Samsung S8 phone, share a file via Bluetooth from the phone, but the transfer always fails. I don't know if it's me, the phone or the watch.

Did you accept the file transfer at the watch? You have to pull down the notification area and have to accept the file transfer.

It won't run on my Samsung Galaxy S8 either.

I hope someone figures out how to install the Google Play Store app on the watch. Aptoide is difficult to use for me.
Also, I noticed that when installing an app, the Install and Cancel buttons are almost not visible at the bottom of the screen. Is there a way to scroll/drag the screen?
Many of the icons are too small for my fingers. Is there a small stylus available anywhere that works with the watch? I installed Chrome so a stylus would help with using that as well.

There are new Versions of the Apps, for watch and Phone. Take a look at
my Postst #2, give them a try. For me it's working now.

Hello Backers,
The first software update is now available and it focuses on the data transfer between the watch and your smartphone app. For those that were having issues with the app and data transfer we’ve updated the software to allow for a better experience for transferring photos from the watch to your phone.
Cloud update services are not available at this time but please follow these simple instructions to update your watch:
1. Enable Bluetooth on smartwatch & phone.
2. Connect them with eachother.
3. Enable the installation from unknown source on your watch. (settings > security > unknown source)
4. Download http://arrowsmartwatch.ml/ on your computer.
5. Once the APK is on your computer, share it via Bluetooth to your Arrow Smartwatch. (if you don’t know, just google how to share files with Bluetooth, it’s very easy)
6. Once you’ve pressed the sharing button, you’ll have to accept the file on your watch.

7. Now go to the file manager and search the Bluetooth folder.
8. The APK is in that folder. It’s labelled Arrow2
#9 is for ANDROID users only and this is your new Arrow Smartphone App. Please download from the following link.
9. Download this on your Android phone http://arrowsmartphone.ml/
This watch update was tested by a few beta testers within the backer community with good results. It should allow many of you that were having trouble to start transferring photos and videos from the watch to your phone. The next planned update will focuses on connectivity, apps and notifications.
As for the remaining Arrow inventory we continue to wait for Chinese customs to give us an answer on the status of our units. They said Chinese New Year would create a delay of up to a month or two so we will post an additional update soon outlining the details of this extremely frustrating and prolonged ordeal. Our goal remains to ship all remaining units to backers as soon as this custom issue is cleared.
Inquiries about the above can be sent to [email protected] as this is our primary contact method.

Thanks! Is this a new version of the OS? Or a customized version?

Hii! Not sure if people are still using the watch.. I took it out last week and again remembered why I packed it back. The battery drain is just insane!
Was anyone able to get a different OS version installed on the watch,,? Is it even possible? What are this risks?
What are my options to experiment?

Eonon GA2168K Radio app and Nova launcher issue

Hello all, I just purchased and installed an Eonon GA2168K 10.1" LCD Android head unit. The stock launcher on this unit is terrible. I've installed Nova launcher and everything looks much better now. The issue I'm having is that the stock radio app is nowhere to be found however when I go back back to stock launcher, it is there. Not sure why it's not available in Nova. Has anybody else experienced this problem? Any help will be greatly appreciated.

Yes it is because it is a custom function for the head unit, so standard launchers can't see it.
Give FCC Car Launcher a try - it's great and should hopefully work for you

Thanks for the suggestion. I tried FCC and still no radio. My old Eonon Android unit on 4.4 didn't do this. I have also noticed that this is a very limited version of Android e.g., missing all the settings in the top drop down menu. Hopefully someone is working on a custom ROM for this unit. I really don't want to use the stock launcher.

Yeah your old one would have been a MTCB with Rockchip manufactured by Klyde - this one is basically a completely different software developer and manufacturer.
What is the MCU version out of interest?

Mcu: Ts907.180712

I've also purchased this same unit. I'v tried a bunch of different launchers and all are no go for the radio app. Really driving me crazy that I can't use other launchers without losing the stock radio functionality.

Good to hear I'm not the only one but sucks at the same time. Though I was starting to worry because I bought this unit refurbished and the software was all screwed up when I got it. It had Apex launcher installed along with a bunch of other non stock apps. These were presumably installed by the the original purchaser and Eonon didn't even bother to reset to factory settings which is something I still have not figured out how to do.
Is your drop down menu bare like mine? Mine only shows the WiFi connection.
Bluetooth is very disappointing too, can't connect anything like bluetooth headphones or a keyboard as it does not show an option to search for devices.
This is not the true android experience I was hoping for.

Ya, mine only has wifi listed in drop-down. I can connect to Bluetooth with my phone just have to go into settings menu. I like the unit, but the custom firmware and launcher that it comes with is kinda garbage. I did get in contact with the seller for the newest update, but it still has issues. Mine has the same radio app issue you described with custom launchers and will not keep a radio preset name. I can set a preset, but as soon as I select another staion whatever is displayed gets saved as that preset name on the channel I was switching from. I did update to the newest 2/21/2019 update, but my unit still has the same bugs. I bought mine through Amazon and I'm pretty sure I'm going to return it as it was not describes as published. This unit could be awesome if it had a better firmware installed on it. I can dump the firmware if anyone wants to take a look at it and possibly fix it's shortcomings.

I just installed a GA2168K yesterday in my 2006 GTO.
A couple things I noteced... I noticed in the included harness adapter is they have constant battery power and accessory power swapped.
Installed it with their R0008 dash cam that came with it. No DVR app. Finally found the main config menu (hidden by password 8888) and enabled DVR.
It does not detect the camera. it works fine with my GA2170. Went to their website and was looking to see if they had a different camera available, and that is the only one. However, on the R0008 camera product page it gives a list of HU's it isn't compatible with, and the GA2168K is one of those. Sent support an email, hopefully will have an answer Monday on that. The other frustration is that half the settings they show in the user manual and online, aren't showing up in the actual menu's. Hoping they can send me a newer Firmware/OS that enables those... And finally, there is no seperate control for subwoofer like there was in the GA2170 Looks like I need to buy the remote amp level control and run a new cable to the trunk
I also need to add that it is advertised as having 18 FM radio presets and 12 AM presets.
Mine is only storing 6 of each and just goes back to the beginning...

Mine has the 18 fm presets and 12 am. Just have to hit the Fm or am button to go to the next set. As for the DVR cam, I remember reading that it wasn't compatible with DVR cams in the Amazon description where I purchased mine. Specifically list the r0008.
So problems I've noticed so far. I've updated to the latest firmware provided by Eonon support.
The addition of a screen off button is nice, but the brightness settings for auto brightness are still to bright at night. I really wish they would include a brightness slider. Maybe a lower setting on the nite slider.
My wifi does not automatically connect to my phone when i turn on my hot spot. I have to manually go into wifi settings for it to start searching for a signal.
My radio presets will not save properly. They only save what is listed when I change the station. Becomes really annoying since it save whatever song data is displayed. I really would like a way to add a custom name to stations so that it doesn't just save the radio data displayed.
I also really wish I could use the radio app with another launcher like Nova. The radio app contains all the speaker adjustment controls and equaliser settings.
Edit: this is the response I got from Eonon after sending them a similar email for their developer to hopefully look into and correct some of the quirks of the firmware on this head unit for a future update.
Hi，
1, regarding the brightness, currently can not be set lower.
2. Because the WIFI hotspot of the mobile phone will automatically enter the hibernation state after being connected for a long time, when the machine is started again, the WIFI hotspot of the mobile phone is not detected. At this time, it is necessary to manually activate the WIFI hotspot to connect, we cannot change this..
3, currently does not support the storage method you said, thank you for your advice!
4. This is a problem with APP compatibility. There is no way to solve it.
Thank u so much!
Vera
Hmmmm......?
If someone wanted to work on a ROM for this headunit I'm sure I could figure out how to dump it. This head unit has some great potential but has some flaws that I wish the companies devs would fix.

I have the GA9163K (the Mazda version) of this head unit. Apparently the K versions of this model, which generally come with Android 8.1.0, do not support front camera/dvr function. That's what the EONON rep told me anyway.
On my unit, in the advanced menu (code 8888) it had options to change the number of presets on each band and could be selected between 6, 12 or 18 presets on FM and 6 or 12 on AM. It also had the option to enable OT frequency, but not sure what that is as we do not use that here.

Dears,
anybody tried Eonon GA2178 - 10" Android 9 Head Unit?
I'm actually on Eonon GA2168K - 10" Android 8 Head Unit, it's a good device with minor problems.
Anytime developers fix a problem they introduce an other problem and there's no community support for MTK chipsets.
Because of this I'm evaluating the new Eonon GA2178, that is quite similar but based on Rockchip chipset.
Tks!

I found a solution to eonon with no radio,
I installed the GA2180A eonon unit last week and changed the launcher to the paid version of Car launcher by apps lab studio and found the same issue, no radio.
I was able edit the theme and create a widget with 'KWGT Kustom Widget Maker' that basically displayed a picture, I used an radio clipart png file i found with google image search and set the action when clicking the widget to run the Radio activity inside the app installed called com.ts.MainUI8. Your app and activity may be slightly different to mine. I do own the pro key for KWGT, but I don't think that matters.
This is my first post so the system won't allow me to post the google drive link to my custom widget. Feel free to message me for it. It would need modification too.
Depending on the rom installed in yours you may be able to use something like 'Activity Launcher' by Adam Szalkowski to create a shortcut directly to the activity. This is a much easier than the first option, but some roms have the ability to create shortcuts turned off. Mine did so I found widget work around.
The above could easily be adapted to launch other internal activities beside the radio.
Happy to provide more info if I'm not clear. Good luck!

[email protected]

I also have an eonon and would love to get some information [email protected]

I have an UGAR 9 in (model 8227L). It's running Android 9. And has a clunky stock user interface. I used Nova Launcher and "quickshortcutmaker" to create shortcuts to the stock apps that did not show up in my app drawer. Namely the AV-IN and radio apps. So I got that all working pretty well. However, I have not been able to figure out how to get the upper status bar to remain visible. It hides itself after one or two seconds. If you have figured out how to keep the status bar from hiding please let me know. Thank you much

PX5 S32F0 Head Unit Known Bugs: Inputs for Custom ROM deployment.

In this thread we collected enough money to help our friend @Malaysk to buy a device that will be used for a ROM development.
Now I am asking all the owners of a PX5 with S32F0 MCU to help @Malaysk work, reporting here the known bugs of their units. This will help him don't wasting time searching them and it will speed up the ROM development.
Add a post below, reporting the following information (following is mine.):
Model (Vendor): Erisin ES8176J PX5 64 Gb ROM 4Gb RAM Android 10 (Jeep Grand Cherokee)
ANDROID : 175134
MCU: S32F0_LEIMA-W_20200703-16:29_HD1_7708_D_FF_C8
APP: PX5C_C55_HA4_LeiMa_LeiMaUI2-0000-10-JS_2020-07-16-1734
Found Bugs:
1) Bluetooth Settings missed from Main Menu -->Connections (Pairing of devices like OBD, performed inside Telephony app)
2) Bluetooth AD2P App missing (BT Music supported inside the Telephony app)
3) FM Radio AF=On setting lost every time the app is closed
4) FM Radio "power Off" button missing
5) Bluetooth Ring and Call Volume too high at every reboot (settings are lost)
6) Stock launcher has only 2 desktop spaces for the Apps and is not possible to add more.
7) Steering Wheel commands are "pre-defined" in factory (Can Bus) and cannot be changed (The App is working only with resistive one)
8) "Ok Google" not working. It is impossible to enable the voice recognition learn process (button greyed)
Suggested Improvements (Ideas for @Malaysk):
1) Root
2) Rework of the apps GUI (Radio, BT, Music, etc.)
3) Customizable list of the Apps that are running instead of the stock
4) Complete Power Off button
5) Battery Voltage in status bar
6) Status Bar customizable in terms of items, size, etc.
7) Customizable Steering Wheel codes
8) Screen light intensity auto dimmed by Time of the Day
9) New launcher with media info on the home page

APP: PX5C_C55_HA4_LeiMa_LeiMaUI2-0000-10-JS_2020-07-16-1734
Found Bugs:
1) Bluetooth Settings missed from Main Menu -->Connections (Pairing of devices like OBD, performed inside Telephony app)
2) Bluetooth AD2P App missing (BT Music supported inside the Telephony app)
3) FM Radio AF=On setting lost every time the app is closed
4) FM Radio "power Off" button missing
5) Bluetooth Ring and Call Volume too high at every reboot (settings are lost)
6) Stock launcher has only 2 desktop spaces for the Apps and is not possible to add more.
7) Steering Wheel commands are "pre-defined" in factory (Can Bus) and cannot be changed (The App is working only with resistive one)
8) "Ok Google" not working. It is impossible to enable the voice recognition learn process (button greyed)
Suggested Improvements (Ideas for @Malaysk):
1) Root
2) Rework of the apps GUI (Radio, BT, Music, etc.)
3) Customizable list of the Apps that are running instead of the stock
4) Complete Power Off button
5) Battery Voltage in status bar
6) Status Bar customizable in terms of items, size, etc.
7) Customizable Steering Wheel codes
8) Screen light intensity auto dimmed by Time of the Day
9) New launcher with media info on the home page

For number 2) Bluetooth is a big mess, like you say, we don't even have the option in Settings. I would just like to be able to connect to a bluetooth device using the head unit.
For number 7), it would be indeed nice if we could program Steering Wheel buttons that are sent over CANbus.
additional:
10) Zlink app only supports Carplay, I would like it to work with Android Auto instead. I've seen different versions of Zlink passing by that support Android Auto...

Looks like all the same bugs which exist in MTCX units. Probably a port of the bugs, a copy as the Chinese are so well known for.
Check out the joying thread for the new units with a super cheap and cheerful processor and different MCU; same bugs.

My pre installed version of Zlink is supporting very well Android Auto on my Samsung Note 10.
Perhaps Malaysk could integrate it in the ROM.

Probably the porting is only on the Android part, with the necessary adaptations for the different MCU.

Yes! I'd like that

Bugs:
- unable to update Zlink (its included in the rom once deleted can´t be installed again, only by whole reset, not even the same APK i extracted before)
- ZLink crashing after 2-20 Minutes, can´t update Zlink
- Can SWC is increasing or decreasing Volume by 2 steps instead of one
- no Bluetooth while connected to zlink
wishes:
- customisable physical buttons (long/short press)
- changeable standard apps for radio, MP3 ...
- fix for volume on SWC
- day/night by lightswitch position
- support for a USB hub if possible (not tried it yet), as one more USB needed
- support for Autokit on the zlink-USB-port(alternative to zlink)
- option to really close apps instead of minimizing to taskmanager (have 3-5 DAB-z´s open from time to time)
- button combination to boot in recovery
- customisable apps to switch through when pressing "mode"-Button
- easy way to choose apps for splittscreen
- separate channel to adjust Sub-Out Volume
- display the station or song in the instrument via can
- navigation directions to show in instrument (arrows for example in a VW) via can

USB hub is supported, I have mine connected to a DAB+ receiver and USB stick through a powered USB hub
---------- Post added at 03:30 PM ---------- Previous post was at 02:59 PM ----------
one more bug, I'd like to see addressed:
- when I put the car in reverse gear, it automatically starts the reverse camera app. I've seen 'fixes' that say to remove the app, but I would like to keep the app (I still want to use it when I start the app myself), but not start the app when I put the car in reverse gear. Make this an option that can be selected.
thx!

MCU-firmware is anders; er is een radiomodule 6686 en 7708., controleer, anders wordt de radio niet wakker met geluid..... this i have from the Russian site.!!
I would like to have the option DSP updated to the latest.... i have this radiomodule >> (7708) ... and maybe a new DAB+ app .. that just works better .. instead of the one preinstalled ..

Just use DAB-Z for DAB+. Works perfect for me!
I think you would have to physically upgrade the DSP-processor for real 16ch DSP. From what i read the DSP in our units is a fake. It has just 8 channels.

It would be nice if a balloon with the selected station was displayed on the screen for a moment when changing the radio station. When the radio works in the background and you switch stations using the button, we would know what the current station is.

for the reverse... put the following code in the factory setting screen 0000121, a page should open with additional settings (Boot Config). I remember that I saw something there about "Back Camera". I am not sure about what changing this setting does, but a try could not arm... I hope! :laugh:

Nope... DAB Z should work even if you have the stock app installed. Is one of the first app I installed on my hu and I am using it regularly. Do you have a normal DAB usb dongle ?

1) I wish I could change favorite stations from the steering wheel
2) have the AF function work well and remain set after switching off

Hi .. i really had to uninstall the standard app first for DAB-Z to work .. never the less .. it works .. i don`t know what i have normal or regulair dongle .. i have a window antenna and i think the dongle is in the back of the unit .. however ..DAB-Z is working better than the DAB+ app .. is it normal that at first boot it crashes ?? Or am i missing something ??

Hello everyone. Guys, I just want to write you a few points so that everyone understands this.
1. The device has not even been sent to me yet, the status is awaiting dispatch (it is written that within 15 days, but the seller promised to send it as soon as possible).
2. The choice of sending the device was only regular Aliexpress mail (I do not know how long it will be delivered).
3. Working on the mod firmware will take a long time, as soon as I receive the device, I hope you understand that this is not done quickly. And this is a completely new device for me, although I suspect that it is similar from the forum thread for MCU MTCE.
4. Not everything that you have written here is possible to do.
5. I will try to make a ready-made firmware with ROOT access very quickly and post it here.
Thank you for understanding. I read this forum, but very rarely answer and do not use private messages (there is only one spam)

Does somebody has the stock Launcher in .apk file ? If so can you give it to me .. i have no idea how to extract it from my unit .. !
I want to delete it and then go on with only the AGAMA Launcher .. and in time reinstall the stock one .. its not in OEM applications. That`s why i ask !
Or maybe all the stock apk`s.

Android unbranded for car lost Zlink

Hello all,
I've just got an Android unbranded tablet for my car (BMW E82) yesterday.
It's a 10.25 touch screen with Android 10.
Under System Information, I can read: version HY: V2.32.4core.201113.
I can enter to factory settings via 8888 code.
It came with Zlink already installed, and I could make it work perfectly yesterday with my iphone & wireless carplay.
(I can't remember actually if it was Zlink or Zlink5 but it worked good).
Today, I mistakenly cliked on reset to factory, and after the headunit rebooted, the Zlink app is not present anymore.
I am struggling to get it back...
I have found some Zlink apk files in forums, but none worked for me.
Does anyone know if it's pre-installed somewhere on the head unit, and I just need to enable it ?
Or should I install it with an apk file ?
Thank you in advance,

The Zlink app that I have found in Play Store asks for an activation... Which seems to not be free.

i think you can find it in settings then in factory settings it might your factory setting have password 1617 or 2010 try any one of this password. there you will find the option name feature settings in there find “phone connected” or something like this tick that option and you are ready to rock again.

Hi Rooblevarn,
Thank you for your reply.
I tried the 1617 and 2010 passwords, but they don't work on my Head unit.
The only password that worked for me so far it's 8888.
I can then get into a factory menu as shown in attached picture.
I have looked everywhere in those menus, but I can't find anythink similar to "phone connected".
I suppose that Zlink app was installed manually by the vendor before he sold me the head unit, and the only way for me to get Zlink back, is that the vendor send me the file that match this unit to be installed....
Problem is that I don't have vendor contact.

I've been in contact with one of the vendors of an Android 11 HU I recently purchased,
#1 - It's tough to communicate with them
( they are all in China, and it's clear they translate English using Google-T )
I don't know the specific build for your system, but Zlink is somehow tied into the entire Android Build Version which they custom build for each HEAD Unit.
I have provided two different files here. READ this carefully.
The file starting with:
gongban_92_Zlink - is the older version of Zlink. It may be less resource intensive, but it works similarly to the new Zlink5 version.
The file starting with:
gongban_F92XX_Zlink5 - is the newer version of Zlink ( or at least as new as it can get) ( This was given to me by the manufacturer's tech dept in March of 2023. )
The way I was told to install these is to:
- Save which ever one you want to install onto an empty USB stick.
- DO NOT change the name or the extension of the file.
- Plug in the USB stick
- Open Your App Drawer > Find Car Settings > Find System Information
- There could be a button on that System Information screen that says: Android Update ( This button was greyed out(unaccessible) until plugged in my USB drive.)
- You hit that button and wait for the update to finish. everything is automatic from that point.
- When successful you would notice a new Zlink app in your app drawer. It might even automatically launch after system reboots.
BEFORE YOU GO TRYING THESE STEPS THOUGH:
Understand that these apps are custom built to access bluetooth and Wifi functions of the Android system.
If they are not installed correctly they might
A: Not work at all
B: Brick your device
Here are some photos of the specs of my device and some screen shots of how the settings pages look and where you can find update options (given you have the right update files):
How old Zlink app looks:
How new Zlink5 apps looks:
Settings Page:
and finally ABOUT FACTORY SETTINGS and your app disappearing:
When you hit Factory Settings ( and get into the main screen:
You should see an option called APPS:
When you enter that there could be a screen with the header: XYZ apps
XYZ apps is a custom system settings app which forces apps to boot with the head unit, and never allows them to force quit. ( This app in not attainable on the app store - is what I mean by custom)
Before you go installing any updates or files, find the APPS section in factory settings and see if Zlink is on that list.
The list is "check-able" - like toggles or check marks
- If you see the app there and it is UNCHECKED then CHECK IT, go back a page and find Reboot.
Then see if you app appears again.
If you don't see it.. well.. that's beyond my understanding, but most likely you would need to install them through a USB port like I detailed above.
Weather or not MY attached files will be suitable for your system is a whole other question.
One other thing:
- I'm not a developer and I don't know how build versions work on Android and how each aspect of each function affects other aspects:
But it is clear that the Chinese devs who write these Android builds are forcing certain apps to run in the background.
Having said that.
NEVER connect your Android head unit to Wifi and use it to access Personal Information or store passwords.
These aren't ATT or Verizon head units. They are made by a foreign company who is most likely under the umbrella of laws and regulations which allow the military to snoop on customer data in the name of the motherland...
The only way I use my headunit, is for it's radio, and the Android Auto function for navigation.. (whenever Zlink isn't crashing)
I don't allow any internet connection to the unit as it is not necessary. As a driver all you need in a car is a map and some tunes.

Thank you for your reply ! It helps to understand a lot of things.
Well, today I went back to the (physical) shop where I initialy bought the device last week.
I told them that Zlink is no more available and to me, it's the most important feature on the tablet.
They tried to reapply a new Reset factory settings, expecting that Zlink will be back with that, but it wasn't back. As they couldn't find a solution, I asked to replace the HU.
At first, it was a 2/32 GB (Android 10), and they replaced it with another with 8/64GB (Android 11) from the same manufacturing (on the box I can read J-1018)
Wouah ! Now it makes all the difference !
The device is much faster, and now when I go to factory settings (with 8888), I can find there a menu, like the one you are mentionning, called in my device "Type selection" as seen in attached picture.
This menu was not present in the previous 2/32 GB device...
Now as per the seller, even if I hit on Reset factory settings, I will always have the ability to restore Zlink (which a built-in version, quite old as it is 3.8.8 but it does the job).
I think we could have found a solution on the 2/32 GB (Android 10) with the help of your files. But I don't have anymore the device, so can't test it.
I hope someone else from the forum with the same problem can test them, and reply back if they are helpful.
In all cases, I am happy that this issue occured on the first device, because thanks to that, I have now a 8/64 GB instead, and I can only recommend to anyone buying a new Android HU, to choose as minimum 4 or 8GB of RAM, and 64 or 128 GB for stock memory. It is the minimum nowadays.
