Joying UIS7862 7" setup (Including working Android Auto Wireless) - Android Head-Units

Playing around with my new unit to try and get it configured. I thought I would share what I have done so far and issues I am having.
Root:
I tried creating my own flashable image, but it did not like my 6315_1.zip file, even when signed with SignAPKv2. I was able to decipher my way into 4PDA where a user had submitted a working boot image patched with Magisk (attached). I updated to Magisk 22 from the Magisk Manager after install.
Android Auto:
Three ways to do it.
CarLink (aka ZLink)
This has worked quite well for me, but only supports wired connections. Hopefully they will update soon.
HeadUnit Reloaded
Wireless Android Auto (Note: phone calls not at 100%)
You need to be on the beta version of HUR which supports wireless android auto.
For Joying to support it, you need to change the config.txt build prop to sys.fyt.bluetooth_type=0 (you can flash link below bluetooth0.zip).
Phone calls do not come through the stereo. In HUR I get the error "Bluetooth is not connected." The phone shows an issue with bluetooth connection and says to try rebooting.
I don't know if this is an issue with the unit and it's dodgy BT or if it is the beta version of HUR.
I'm trying others to see what happens with different settings
0 = Wireless AA, unreliable phone over BT
1 = Factory default, no wireless AA
2 = Bluetooth cannot connect to anything
3 = Bluetooth cannot connect to anything
4 = Bluetooth cannot connect to anything
***Potential workaround
Phone seems to work again if bluetooth is turned off then back on. This does not seem to affect AA since it is running through a direct wifi connection at this point.
I have set a tasker task to turn bluetooth off then back on when it sees the wifi direct connection made.
The phone still says "Bluetooth is not connected" during calls, but the
Base HUR settings to not take advantage of this really nice display. I set the following in HUR's graphics settings for a big improvement:
Resolution: 1240x720
DPI: 200
Render surface: SurfaceView.
Android Auto for phones
Looks pretty good. I'd love to be able to use it for other drivers
Problem
Cannot reliably connect to other apps. NPR One and Pandora both say "there is a a problem opening....."
These apps work fine if they are playing before you open.
Adding apps to skipkillapp.prop does not seem to help
Tasker:
Difficulty reading bluetooth connections. May be related to sys.fyt.bluetooth_type above.
Prevent force close when turning car off:
Added net.dinglisch.android.taskerm = -10 to skipkillapp.prop.
Seems to be working. More to come...
Other Issues:
Deletes all google contacts:
Well known issue, remove syncing google contacts under settings -> users -> accounts -> google.
To get contacts back:
Go to contacts.google.com
Select Settings (gear icon in upper right) -> Undo changes
Go back however far you need to when you still had contacts
Recently I reset to factory defaults which killed the ability to connect to google play
Fix found in Joying forums (here).
Download firmware and place on flash drive
Go into app setting and wipe storage for Google Play Services
Immediately plug in firmware USB and let it reinstall
Magically works again after reboot
FytHWOneKey
Doesn't seem to work on this unit. Developer previously mentioned mute button (seperate in other units) was a direct android call which could only be captured with Exposed?

Hi fellow, I follow ytour post and see that you know what you're doing with the headunit
I come here asking your help
I can't see the mobile network icon in the SystemUI like the photo below (taken from4PDA forum)

I wonder what sys.fyt.bluetooth_type=0 does in hardware terms.
The UIS7862 unit has bluetooth onboard of the SOM as well as an external USB attached Bluetooth module.
So does sys.fyt.bluetooth_type=0 select the onboard Bluetooth and sys.fyt.bluetooth_type=1 select the external USB module?
If this is the case then it may be necessary to attach a bluetooth antenna to the Unisoc module. Although I believe one of the WiFi antennas does double duty as a bluetooth antenna for this purpose.

Correct.
Do not use sys.fyt.bluetooth_type=0 on uis7862 FYT. Doing so loses bluetooth Low energy (BLE) and your hands free audio likely sound bad.

Is there a page I can go to in order to see all the options to put in the config file in order to customize it. I love had my unit for a while but am just learning how to customize the firmware

Bluetooth option is missing from device settings menu

Hi.
I bought a headunit via ebay.
At device settings under wireless & networks section only wifi option is exists, bluetooth is misssing.
It must be bluetooth capable, because it works with android phone. Only one bluetooth icon is on the device homescreen which operates only with phone calls, contacts.
We have a bluetooth ODB item, but we cant connect it to the cars headunit, because there is no separate bluetooth menu under the device settings menu, where can i search or find BT devices, and therfore i can not pairing this ODB device to the headunit.
How to solve that problem? Is there eny idea or advice?
Sorry for my english...
Model number: CAR_G20
Android version: 5.0
Kernel version: 3.4.67
Build Number: ALPS.LD_kk1MP10.V2.2
MCU: XY-M4-AndroidBT-4730EU-180408
I have the same problem. Did you found the solution?
Many head unit suppliers do this. They compile a crippled settings apk without bluetooth settings.
There is not much to be done about that.
I have this on my unit, I bought it from Seicane (haven't found out who the manufacturer is yet).
The bluetooth isn't available to android, as it is a host device (can be speaker and hands free kit, not normal profiles for android).
Unfortunately even plugging in a USB bluetooth dongle doesn't help as they have crippled the settings
android settings, in the upper right corner of the magnifying glass icon, press. manually enter bluetooth, you will find bluetooth settings. in the bluetooth program, from the pairing of the phone, change the name and pin to 1234. ready
Android bluetooth

No, you won't. You are talking about the Settings apps on phones. Most head units Settings program don't even look like the phone settings app as they have Settings apps which combine Android settings with car settings. . Most head units Settings apps don't even have a magnifying glass icon to tap on.
What's more: The Settings apps in Joyings are compiled without bluetooth settings, and this is the case on many head units. You can easily see this if you decompile the apps as they are pure java. Most users do not even realize, but most head unit Settings app lack a lot more functionality than the (mostly) standard AOSP Settings apps on phones.
Joying apps have a special bluetooth app that contains part of the bluetooth settings to do the pairing whith a number of selected devices.
Most head units have crippled drivers with compiled in white lists and black lists that only allow paring the phones and bluetooth devices they sell.
Please let us know which head unit you have and please share a photo of your head units settings screen, with all those users who don't have that. Instead of advising people incorrectly.
For example you could look at this video to see how many head unit settings apps look like. You see the bluetooth app allowing "some" paring. Then you will see the difference.
Still no luck huh?
I just got a head unit that also has no Bluetooth settings and no apparent way to pair with devices. The difference is that mine came with an app called just "OBD" (blue icon) and it is there only to help you pair the OBDII dongle. You just open the app, scan, pair and open Torque.
I didn't find the app in the store, but I'm sure if you reach out to your seller, they will be able to help.
Any update sir. i also have this problem. i want to connect hondata using bluetooth. but my bluetooth only have function phone call, contact.
Bluetooth not same with android phone.
kindly please update if you found solution.
Ummm no he is 100% correct. Worked for me like a charm. Mabey you should pay somebody to do it
Junsun V1 - start equalizer/AUX/BT music/CarInfo... from launcher

Hi!
For some reason I cannot reply to the thread https://forum.xda-developers.com/t/junsun-v1-start-equalizer-aux-bt-music-from-launcher.4237797/ ( it keeps asking me to log in/ register and then sends me back to the homepage).
I just recently bought and installed a Junsun V1 Pro (got the base model - 1GB + 16GB).
I downloaded the bluetooth settings apk and installed it with the apkinstaller that was already available on the head unit.
For some reason the bluetooth settings apk keeps crashing when I try to open it?
I've never fiddled with things like these before so most likely I'm doing something wrong.
My only goal here is to be able to share internet connection to the head unit via bluetooth, since BT is always active on my Galaxy S10e and I can't be bothered to activate wifi hotspot everytime I get in my car.
Any ideas?
Thanks a million!

Install the app QuickShortcutMaker and try to find the activity to find and start Bluetooth devices list.
I thinks it's not 'BluetoothSettingsActivity' - but I don't know why...

Hello friend, I think that for your phone to share the Internet every time you get in your car you would have to use macrodroid.
I have it on my phone and I have it configured like this:
As soon as the phone detects the Bluetooth connection with my radio, it automatically activates the shared connection.
And when turning off the radio and disconnecting the phone from Bluetooth. It is programmed to automatically disable Internet Sharing.
I hope it helps. All the best!
Can you help me connect Bluetooth obd2 adapter with Nakamichi android car stereo. The Bluetooth settings in the unit does not have the option to change the password which is 0000.All my obd adapters use 1234.Please help.
Also the joying unit in my other car connects with adapters that only have obd2 as their internal name..

AllWinner T3/ Android 7.1.1/ MCU T5.3.19xxxx/ 1024x600 (Wifi BT won't auto connect)

This headunit was installed in my Mazda 5, it comes with Google Play, 2gb ram / 32gb rom. I am trying to keep it simple with the following launcher / apps installed, but I am facing a lot of pain points now.
App installed:
- Google apps (play, youtube, chrome, map, find my phone)
- OBDII app (Torque Pro)
- Dash cam app
- TPMS app with USB dongle installed
- Car Launcher
Issues I am facing:
1. Wifi will not auto connect to my 4G USB dongle (need to click SSID manually; auto connect to cellphone hotspot is no problem)
2. BT won't connect to OBDII connector (I tried 3rd part BT app, it seems the system disable BT config)
3. Popup message asking me whether the use TPMS dongle as default USB device (even I clicked by default, it prompts every time the unit startup)
Any allwinner expert can give me a hand?

Hey, any luck with this one?
I have the same unit and I am having BT issues (bad bluetooth telephony quality and lag).
Exactly the same issues i was having with my T3 Android 7.1.1 MCU T5.3.19 except for usb TPMS wich works perfectly.. Maybe I installed it in a lucky usb port?
I resolved the hotspot thing by buying a separate bluetooth usb dongle and setting tasker to turn on hotspot when paired to that bluetooth.
I still cant get OBD2 to work... Build in BT is super buggy... Android phone keeps dcing from build in BT.
Id like to root but cant find anything related to this model.

Anyone knows how to fix these issues - Android 10" head unit

I have this unit, (image) bought from aliexpress.
Very happy with this unit that is very fast compared to old unit.

I have following issues that i cannot correct, no matter how much i google i cant find correct solution:
- Bluetooth will only connect to my phone, not to OBD2 adapter. There is no settings for bluetooth in the settings, so i cant even find the adapter. Is there any bluetooth fetures that have been crippled for some units?
- The EQ is very bad, seems it has some presets that all sound ****, except for one, and if i try to modify that setting it reverts back to very bad sound. If i make exact copy of the good EQ setting, under the "personalized" setting, still the sound is not the same. Seems the EQ is just BS. Is this a common problem, any solutions?
- Reverse camera image is inverted / mirrored. And when i change this setting in the settings, nothing happenes to the image. No matter how much i change setting. Anyone knows good solution? There is impression for me that settings does not affect anything, its just a marker in the setting menu.
I would be very happy for any suggestions towards helpin these issues.
I am using Pulsar media player for music - only. (no spotify or other streaming services)
Do i need to provide other info in order to solve these issues?
Thanks guys!

Set BT pass on head unit same to OBD2 pass. That resolved problem with my OBD2
I have the same issue on my HU, but it's different to your HU.
I can also only manage the Bluetooth through the phone app. Often the pair just don't work. It fails to connect to odb2.
What you mean with "Set BT pass on head unit same to OBD2 pass. That resolved problem with my OBD2"?

I think you didnt understand my problem.
The bluetooth options are completly removed from the settings menu. There is no setting for bluetooth to be found.
I cannot even search for BT items.
The phone is paired to the android unit from using the phone app. However that will not allow pairin of OBD2 or any other BT units.
Are there some units crippled not to accept BT pairing with other units?

You need to change the BT pin on the main unit, to the one defined for your OBD2 adapter e.g. 0000 on this picture change to 5678 or 1234 or 2345 .....
Ah okay, i tried it, but still same issue. I contacted the seller.
My problem is that there is no bluetooth settings at all. There is no place in settings where i can choose bluetooth to sync any bluetooth items. Only in the phone app, and that only allows to sync phones.
Is bluetooth disabled in this unit?
What do you see at the connection icon left to it.
tomygunner said:

Connection settings left to what?
The normal place for bluetooth in the settings has not even the word bluetooth. Just wifi.
On the other units there is also bluetooth settings in this place, however on this unit there is not.
I tried to download other bluetooth apps to activate it but non of thos apps work on my unit. However the phone conncets perfect and has good range..
What do you see when you Click on that icon?
I now changed the OBD2 unit and managed to establish contact. Even if this unit was showing on other units, it was not showing on the head unit.
Now the BT is working as expected, still i dont have any setting for bluetooth inside the settings - where it should be.
Other problems still remain.
Equalizer is not working good at all. Seens that only one of the settings is working, rest is very bad soundquality. Even if i make custom preset exact same as "rock" sound is completly different. Like night/day.
Also i cannot mirror the cameras, the unit does not understand mirror and there is no difference in image when i klick mirror button in settings. So left becomes right and vice versa.
I noticed there are TWO EQ apps running same time.
Anyone seen this problem before? That might explain why sounds is like ****.
I tried to forcequit one does not help.
Any suggestions?
Dear goodfidelity, I have same issue with bluetooth
did you find any solution to your problem?

Android radio and problem with central lock after install -Citroen ds5

Hello Everyone. Sorry for my bad english not my native language.
I read all internet and cant find solution to fix my problem.
I buy this Heade Unit - https://pl.aliexpress.com/item/4000...t_main.21.21ef1c24K3NInA&gatewayAdapt=glo2pol
Afrter install everything working fine (steering wheel buttons, 4g, GPS, etc) only one problem with cetral lock. When I turn off the ignition after about 5 minutes, the central locking does not work with the remote control, and when I turn it back on works normally. Funny thing is that 2 people bought this radio but with android 10 (i have 11) and they all work.
I check canbus setting in the herad unit option and i have RZC >Peugeot/Citroen>ALL. The name of canbus is Raise but i dont have on the list that name. I can change RZC to ALLWORLD>Peugeot/Citroen?DS5 but what I wouldn't choose the door functions,sensors etc - not working. Only RZC >Peugeot/Citroen>ALL. have correct setting, but what about cetral lock? how to fix that -it looks like the radio puts the key module to sleep. in the settings I have something like lock control but some pin wants:

You really should contact the seller.
As you did not show MCU and Android version, no one would be able to help here.
On top: The French cars are some sort of difficult and b i t c h y, when it comes to CAN connection and providing car functionality. May be you got the wrong CAN adapter.
Spoiler: photo about device
Seller send me canbus Raise like one the pictures
Spoiler: CanBus
tell me what to do?
And last thing he send me RAISE can bus and when i check in the settings i don't have that Can BOX TYPE, and must use like on pictures - because it's the only one that works (steering wheel buttons) but no central lock
Spoiler: CAN BUX TYPE
but i can update this:
Spoiler: UPDATE CAN BOX
can a bad canbox setting cause this problem?

Yes sure. Even if you chose the wrong type (low, mid, high)
Remarks:
That the door lock is not working anymore with connected radio, that tells me that there is a mismatching CAN box setting. Seems to deactivate the central locking mechanism, there is an interference in the CAN signals.
That should throw an error message in the OBD for sure. You need to get in contact with the seller again and tell him that there is an error which deactivates the central lock.
Ask the seller which CAN box settings to use. If the sell units for your car, they should know which version to use to get at least most things working as expected... But you should know: There is only a minimal set of functionality available for most cars. Mostly they are providing Clamp 30, Clamp 15, RVC and light.
If your car is not listed in the CAN settings, you should not count on any further functionality.
You can update the CAN box, if you have the right file for it. Did the seller send one to you?
I checked all settings. I can mark my car on the list but if i do this steering wheel buttons not working (only on that HIGH). I Update canbox but its nothing change (no new funcion, settings etc) work like basic.
maybe some settings of the radio cause the BSI to go to sleep. some function consumes energy and bsi sleeps to save energy.
Just to drop here some info that may be useful to someone. I had precisely the same issue with the central locking system on a Citroen C4 II e-HDI, basically same stuff as DS4. The problem was the canbus decoder (Raise). I was sent another one from simple soft (XP type) and it works perfectly. maybe it's helpful for someone else. regards
Sorry to resume an old post but I've finally managed to solve this issue without external players.
Basically, what happens is that the ****ty Canbus BOX "raise" it's like always connected and draining energy.
You can lost a lot of time talking to the chinese seller, OR (if you have a bit of DIY skills) you can simply connect the RED wire of the canbus box to any power source that goes on when ignition is on (for example any led or the lighter 12v).
After that you'll enjoy a car without any chinese headunit added issue!! Cost of this? 0 euros!

Head unit without Bluetooth to OBD2

It shows dummy plug in the tourq app and any other bluetooth apps I've tried.
I don't know if it's an hardware or software issue\limitation.
I'm attachig mt HU info and I hope it would be usefull

saw a few posts here about that other people can't connect the device also, they don't mention the BT options, and I can't access to the dev options only the factory settings requierd password, the password 126. (8888 gives me options to change boot logo)
the only option that's works for me(was the defult one) to connect my phone and see it in the bt app is this: GOC_BC5_3008
In the other options I can't see my phone and OBD2 when I try to detect new bt device.
Someone with the same issue
Bluetooth connection issues
Having trouble with OBD dongle. Have installed 3 apps and although dongle will pair with head unit, the only option to select within apps says 'dummy FF:00:00:00:FF:FF'. This comes up even if dongle isn't plugged in but at the same time dongle...

Which suggests its a issue with the unit.
You both look to have a PX5 (well maybe as you can never tell 100% with these units)

I tried this, saw the comments.
I can't change my BT password it's on auto option.
In other BT options in the factory settings I don't see on the bt app my phone or the OBD2, tried them all, some even crash the app.
tried to reset the bt and wifi settings but no change.
Post in the MCTD section, they are the maker. But the BT function is deliberately crippled in these units so finding a fix will be hard. I went FYT as the maker and can use OBD on BT and UsB.

sorry I don't know what FYT means.
The 2 major makers are FYT and MCTD, there are 100's of sellers but most are made by these 2 makers.
