I Dont understand why my Menu is complete different to all of your Menus even The Canbus code 8878 is not working

I Ask Junsun today how i can change my CanBus for my Audi a3 8p and i get send this Picture :

With this Manuel my Sterring Wheel Control works but i see so many Videos on Youtube then they change the canbus it showas when door open and they have a App from Junsun on the radio how can see Rest Fuel Tank in L and How many KM the car is driven etc and is the Handbrake use or any Door open etc

And when i want to change my Bootlogo i got this massage :

How to change the startup logo: (1) Prepare a USB flash drive, change the name of the logo image to zxdzlogo.png, and copy it to the root directory of the USB flash drive. (2) Insert the USB stick into the 4PIN or 6PIN USB interface of the machine (3) Click ① Settings>② System>③ About the car machine>④ Local upgrade>⑤ Start the upgrade Requirements for startup logo file: the format must be. png image, and the image resolution is the same as the current machine's display resolution

Have i a complete New CarLauncher from Junsun? or is this the New "UI 4.0"?

And when i got to the "Normal Setting" anf go to About Device and tap 7 Times on the version to get the "Developer Mode" i must Enter a Password i never saw this on My Handy i must never enter a Password

Akú verziu inštalujete? Všetky funkcie fungujú?

Mám Toyotu Avensis, ale neopravil som všetky funkcie z Canbusu, Zámok dverí z P alebo do P. Pôvodná cúvacia kamera funguje s hnedo-ružovým prepojením.

Mám Junsun V2 Plus 6/128 GB, ale skutočných 4/128 GB s Androidom 10 real, verzia 8667 v10 z 26.6.24, 3D UI nefunguje, nie licencia.

"I Dont understand why my Menu is complete different to all of your Menus"

Because you have different HU, with different CPU and different system CORE. ;)

My joy was premature. In the evening, after starting Google Maps again, the navigation locks on the maps.
[Android Head-Units] AdekP:
I have a strange device, apart from the wrong aspect ratio, I don't have a navigation selection menu :D
[Android Head-Units] Tekjeep:
Looking for latest update for this HU. FF_866X VHD-XHS-N10
[Android Head-Units] gduck:
LOL. Strange... What information is on the About screen? MCU, ....
[Android Head-Units] vlad_adrian:
hi, I see it's Tengshi, not Junsun, I don't know if they are compatible with each other, maybe an experienced colleague knows.
[Android Head-Units] AdekP:
MCU: G6-TS.230322 (SAT-7705N-9)

Is Tengshi firmware safe to install? I saw that you posted a link to the firmware and later warned against installing it ;) I have an idea to try from Tengshi again and if the aspect ratio is still bad I will return the device and look for something else
[Android Head-Units] gduck:
So, this is the second version of this firmware and it can be stated that the middle open door display is disabled

due to the 3D car open door display.

If you choose the built-in UI04 theme or another launcher, there is no open door display. That's why I removed the limitation. I have attached the modified MAINUI version (I also enabled PIP support in it).

PS: If you user 3D car launcher during the middle open door warning display, the 3D car disappears!
[Android Head-Units] gduck:
Yes, if the firmware is 8667Q, but not all versions have FAN support enabled. But it can be solved! The old comment is no longer relevant, I will update it!

You can download Tengshi firmware from HERE ;)
[Android Head-Units] AdekP:
Ok I think v29 is from Tengshi? Is there a theme with PiP and maps?
[Android Head-Units] gduck:
Both firmwares are from Tengshi.

About v56, only one built in Launcher (my favorite, I modded) with PIP.

About v29, contains 9 built in Launcher, please see the pictures ;)

Hey there,

What's the latest firmware I can use with my actual Junsun Unit ?

Here's my actual FW (attached)

What's the difference between UI02, UI03, UI05, etc... ?

And can I use firmware which are called 1280x720 even if mine is called 720x1280 ?

Thank you.
[Android Head-Units] cstalex:
Btw actually in my FW I can use Android Auto with wired and Carplay in Wireless.

Do you know if there's any solution to have both Android Auto and CarPlay working with wireless ? With lastest FW ?

Depending on the wired or wireless mode the cost was more or less important when I bought it.
[Android Head-Units] gduck:
About JUNSUN, two firmware versions available:

8667Q军灿UI02-国外-1280x720_v48_20231201.zip

or

8667Q军灿UI03-车模--1280x720_v10_20240626.zip

PS: and this is the G6-TS.220713 MCU update. But this is quite a critical update, there is no feedback on it. I have a newer one from the factory, so I couldn't try it either.
[Android Head-Units] cstalex:
Thank you.

What are the differences between V48 (ui02) and V10 (ui03) ?
[Android Head-Units] cstalex:
And where do you find all those links ? Is there a platform we can check regularly to see if there are new firmwares ?
[Android Head-Units] gduck:
This is my UI03 V5(previous version) update experience, you can see what is the difference.
[Android Head-Units] cstalex:
Well it doesn't allow me to download v48. It says too many people did it :-(
[Android Head-Units] gduck:
Strange, I can start the download...
[Android Head-Units] gduck:
I collect them like a squirrel collects acorns :D There is no official page, it is shared by forum members ;)
[Android Head-Units] cstalex:
Alright, cool. I've been able to download with my phone, thank you.

Last question : When I bought the unit, there was different versions (differences in RAM, storage, etc).

Some unit were sold as working with Android Auto only with wired + CarPlay with wireless

Some were sold as working with both in wireless, etc...

Actually I can use my unit with Android Auto with wired only and CarPlay with wireless.

Do you know if there's a possibility to make Android Auto and CarPlay both working with wireless ?
[Android Head-Units] gduck:
So, I'm talking about two programs:

- High definition recorder_0811_v2.1.1_overseas.apk (S700S compatible) package: com.fvsm.camera

- HD DVR_v1.0.0.apk package: com.ankai.cardvr

In the UI03 V5, the DVR widget (see the picture) opened the S700S progam, but in the UI03 V10 the DVR widget open the HD DVR program.

The ADAS warning compatible Launcher (in US03 V5 and V10), using the com.ankai.cardvr reference during the ADAS warning monitoring.

The HD DRV app not compatible the S700S camera, that why we don't see the ADAS warnings. Until our S700S camera is compatible with the HD DRV app, we won't be able to see it. The response from JUNSUN support is the usual: we are working on it... Well, let's be positive. ;)
[Android Head-Units] gduck:
Sorry, no experience, I'm using only the Android Auto.
[Android Head-Units] vlad_adrian:
For Csralex, I also had V11, I switched to V12, V13, V53, now I have V5 from 2024. The resolution is not a problem, the sound is better at the resolution of 1280*720. I recommend V53, for V5 with a 3D machine, they must also be installed other apks that you can find here on the forum. And if you want an excellent sound (quality not volume) you also buy the amplifier from Junsun, there is a very big difference in the sound.
[Android Head-Units] cstalex:
Just updated to UI2 V48, Car Info app is launching, but I can't change parameters in the app. It doesn't apply (for example, if I want to switch from English to French, or if I want to switch from KM/L to L/100KM for the fuel consumption). Do you guys already encoutered this issue ?
[Android Head-Units] cstalex:
Maybe I'll try UI3 V10 and it will work
[Android Head-Units] cstalex:
Alright, thank you for the advices. :)
[Android Head-Units] vlad_adrian:
the complete menu of the radio? I don't think the values are changed
[Android Head-Units] cstalex:
What other apk do you specifically recommend ?
[Android Head-Units] gduck:
Most variations and improvements were made in this (CANBUS communication) part... Maybe this is a BUG...

You have Peugeot too :D For v48, try my fix, but this is only force L/100KM.

PS: in v10 some changes in the PSA part, related the fuel consumption settings. Maybe try...
[Android Head-Units] FiShBuRn:
@gduck , do you have v10 patched for AppSwitcher?
[Android Head-Units] gduck:
NO, please ask TorstenH, here ;)
[Android Head-Units] JMA_25:
Hello,

I have a JUNSUN V1 9" 8/128 MS98.

the firmware was 8667Q UI02 VHD720x1280_v6_20211021 X=1280 Y=720

I tried to upgrade it, but my power unit fried during the process...

now it starts, I see the logo, and then it's stuck at "=> FASTBOOT mode..."

I tried many times, with many different combinations on the RST button to enter recovery mode, without luck.

the "buttons" on the left don't have backlighting, so no way to know when the recovery mode can be activated...

I also tried with usb key to push a new firmware but the key is not read.

If you have any idea of how I can enter recovery mode, or other solutions to upload a new firmware that would be awesome!!!

Thanks!!!
[Android Head-Units] gduck:
Luckily, the recovery firmware update works even with a completely dark screen! So you're doing something wrong.

1. Use a FAT32 formatted USB drive for the firmware files.

2. Extract the 8667.bin and 8667.upd file to the USB drive

2. Connet USB drive to the 4 pin (JUNSUN connector side) USB

3. Use the RESET button OR unplug it completely

4. when turning on the head unit (either from the car's power supply or from the RESET button)

- touch the screen with five fingers, until the update starts

OR

- swipe your fingers on the screen maniacally, until the update starts

After that, head unit booted from USB and the installation starting. If it doesn't work, try several USB drives!

Ensure continuous power supply, the update may take up to 10 minutes!
[Android Head-Units] AdekP:
So I installed the firmware from Tengshi, it didn't help with the wrong screen proportions, and I gave up using Tengshi because of the old school graphics of the radio and equalizer ;) After returning to v10 now I can't log in to the play store or add my account to the device at all :( I cleared the store's cache, updated it to the latest version and still nothing. My device is now useless for anything other than listening to the radio :D
[Android Head-Units] gduck:
Interesting, what is the error message? I've swapped firmwares about 30 times, but I've never encountered such an error...
[Android Head-Units] AdekP:
No error message. Device afer start google play stoping on "checking Device"
[Android Head-Units] JMA_25:
Thanks for the instructions.

I tried with several FAT32 formated USB keys, with 4 & 6 pins USB port, and different 8667 firmware versions, I get either to the circle with erasing message, either the "detected" message in green but I never get to the "upgrade from USB" after "detected" as I saw in some videos.

the led on the USB key blinks one time on startup, but never after that.

Any other ideas?
[Android Head-Units] gduck:
Did you tried a five fingers (continously) after full power down (remove car battery) and start?

You are doing something wrong or the usb drive doesn't like it. The recovery update is the first step of the boot, but the boot process continues for you... Either you recovery start the process wrong or it doesn't like USB drives. Are you sure the format is FAT32?!

try this also:

-Take the paper clip and press the reset button 1x, just press, dont hold

-The device will restart and when the boot logo appears again switch the power off/ turn the key/ ignition off immediately. (or remove the battery)

-Wait 10 SEC and turn to ACC/Power on.

-If everithing went well a "green loading bar" shuld appear on the screen with the tex "UPDATING" or something similar, sometimes the screen is black but wait patiently the update is in the background

-The update took me approx. 5-10 mins.
[Android Head-Units] JMA_25:
I am on an AC adapter. so I tried with reset button or complete power down

5 fingers tapping gets me to "erasing",

5 fingers continuously swiping gets me to "detected",

and continuously touching with 5 fingers without moving gets me directly to "=> FASTBOOT mode..."

I also have a grey screen before the display of "=> FASTBOOT mode..."

I don't know if this is relevant
[Android Head-Units] gduck:
"5 fingers continuously swiping gets me to "detected""

Do this, but after the "detected message", remove your fingers from the screen. What happened?

Another idea: maybe the update process is "stuck" at the last (erasing) part. If you see this and the HU goes through and restarts, then try to start the recovery process (swipe your finger (only one enough) on the screen maniacally) again.
[Android Head-Units] JMA_25:
no changes, it goes to fastboot mode

I am not sure I go to this process, but one finger swipe get me to detected too.

Are there other ways to get to the recovery menu other than 10sec RST button then 2 times RST button?

without blinking button info?

I also read and tried 4 times RST button once you see the logo but also doesn't work...

that could get me to the upgrade from USB option...

Thanks for the help!
[Android Head-Units] gduck:
Hmmm.... Unfortunately, as incredible as it is, in similar cases, the problem is almost always that the head unit doesn't like this type of USB drive. I still say try another one...
[Android Head-Units] Diogo Mendes:
Hey guys,

I really need your help, please.

I have been facing a problem starting up my Junsun. I send the following videos so you can see.

The First video represents the problem and the Second video was recorded immediately after and, again, the problem. The problem is to enter the "Scan udisks in recovery" mode... I've already tried sleep mode, although the message does not appear, after a few days it erases all settings.

It happens frequently, and after a few days it completely erases all settings.

Has it ever happened to anyone? Does anyone have a solution to what it could be?

I really appreciate your help.
[Android Head-Units] AdekP:
I think I managed to deal with the wrong proportions of the screen... in the "other" settings in the menu with code 8878 I changed the LCD type from 8 bit to 6 bit. I know that this is theoretically worse display quality, but the circle is already a circle and I can already use Agama Launcher without getting annoyed by the shape of the clock :)
[Android Head-Units] AdekP:

Hey guys mb you face this issue i have Junsun v2 plus car Skoda superb 2. Problem is audio its affecting radio/bluetooth/carplay actually whole audio.

Sometimes also screen is like turning off. I noticed its connected with Canbus when i unplug canbus all good but when its plug in i have this error>.

I attached video with error, screens with canbus model and version screen

Hmm... several canbus settings are possible. It may not be the best set up. This is a SimpleSoft (XP) adapter, did you choose from the XP group?

What is you car type?
[Android Head-Units] cowile1479:
thanks for answer, yes i seller said 240 and its XP one i actually choose all for skoda. My car skoda superb 2 FL combi 2013 year. As contact with seller is super hard i just order new canbus "Raise VW-RZ-58" and i will test it, but mb my actually one SimpleSoft is also good but i did something wrong not sure :(
[Android Head-Units] gduck:
The canbus communication part is quite a robust code. A lot changes even with a new firmware version (unfortunately, the changes are not published)

What you can do:

- you ask the seller

- try another canbus module (see if it is more stable or knows more)

- you update the CANBUS adapter firmware (hard to find, maybe the seller can help) to see if something has been fixed

- you update the HU firmware to see if something has been fixed

I seen only these codes:

1 - (RZC) Raise

103 - yfx

143 - HiWord

240 - (XP) Simplesoft
[Android Head-Units] cowile1479:
yeap, i ask seller about new canbus or any aupdate but no help at this point i change HU firmware couple of times but nothing same issues so in my opinion its like canbus adapter broken i already order new one Raise VW-RZ-58 and i should use it with this 1 - (RZC) Raise

Hello, anyone know if it's possible to modify the main app of the headunit to support Spotify in the instrument cluster? I have a VW Passat B6 and steering wheel controls only work if cluster has AUDIO menu open, unfortunately the AUDIO menu only appears with FM Radio, Music from files and Bluetooth (not when using Android Auto), but not from other applications like Spotify. When I decompiled the main app I saw there were references to Spotify, but seems like it's broken or not finished implementation, any ideas? Maybe someone has got it to work?
[Android Head-Units] gduck:
Try this AppSwitcher v3 - smart SWC launcher (for Junsun, Xtrons, Ossuret, Hizpo and similar devices) incl. autostart ;)
[Android Head-Units] fwpasx:
Not sure it will work since the steering wheel controls are not working without AUDIO menu open. I think I need to find a way to have that menu force open all the time which I assume requires modifying MainUI apk.

These are the menus I am talking about that allow steering wheel controls.

Regarding battery drain issue I downgraded from v53 to v48.

It is better in sleep mode now. However after 4 or 5 days the car is parked the battery is still drained and the car does not start any more.

I can switch Sleep to off. However the time it takes to boot is too long and not acceptable for regular use 😔.

I have Astra K.

Some suggestions?

Do someone else have such issues after some days not using the car?
[Android Head-Units] gduck:
Thank you for sharing your experience. ;)

What are the battery specs? Age, Ah (50-60?), etc.
[Android Head-Units] mitjama:
Battery is new (3 months old), 60 Ah, Varta Silver.

There were no issues with battery drain before installing Junsun 😔

I replaced the battery after installing Android headunit because the old one lastet max. 30 min when twicking headunit when the car was not running.
[Android Head-Units] gduck:
Ok, this is a good and powerful battery. According to them, this is how much the head unit consumes. That is, if the car is not used regularly, according to them, it is not recommended to turn ON the SLEEP mode...
[Android Head-Units] TorstenH:
This might be helpful and usually the head unit automatically shuts down after 2 or 3 days. Earlier, if

a) not all tasks can get closed

b) the battery voltage gets too low

Trying pulling the radio fuse to completely kill power to the unit, put it back in and tap the screen with 5 fingers while turning key on, or slide finger up and down, should go into recovery and reset to factory. It will erase any content you've added though.
[Android Head-Units] Andy-Denise:
@james73448 thanks. things don't seem to be going so smoothly. touching with 5 fingers. with 1 press you can easily install a new update, but I found a version that also runs well on my radio with the same start screen as I had.

Hi did this fast boot issue get resolved??

I have exactly the same problem, something went wrong with a firmware update and it will not recover just has the same problem as gamer06 had

This is the unit https://www.ebay.co.uk/itm/384770479698 and its their firmware that went wrong, something flashed up red during the update process and i get the same fastboot problem....I did have various firmwares from this thread working but an update from the unit retailer went wrong.

I have tried the original firmware sent with the unit but that wont recover it...I have tried a fresh download of the sent update and that doesn't recover

tried 5 different usb drives all formatted to fat32 no luck

I guess I have nothing to loose by trying this one in your link. I have alreadt tried many firwares but the unit still does not go past fastboot mode
