Hey,

I recently bought the Junsun v1 plus (4/64) variant for my VW Sharan and now I want to update my firmware to the newest version (their aliepress website shows something about UI 4.0). Is this already available or should I install another version. Also are there alternatives to the Junsun firmware. The most important thing is the Wireless CarPlay Connectivity (currently via Carletter, which I just can't find on the internet), so if the firmware has that feature it fits for me.

Thanks for your help,

JakoLex

Edit: In CPU-Z it tells me my model is MT6768 and according to this post I have an MTK8259
[Android Head-Units] TorstenH:
Very good. That's a step in the right direction.

Now we know that whatever wire you connected to the head unit is always providing 12V+. And not only while reverse gear is active.

Is the wire that was connected to the head unit coming from the can box or is is directly connected to your car?
[Android Head-Units] MehdiNdj:
Hi everyone,

I have a Junsun V1 Pro 8gb+128gb dating from 2022 and I wondered how do you check the version to know which firmware to install.

Because I see different versions like MTK8259 etc...

Here is a photo of my "About" info on mine.

Thanks!
[Android Head-Units] TorstenH:
Looks not like a MTK825X. Install CPU-Z to get the required details.
[Android Head-Units] JakoLex:
So I just tried flashing any of the files from the first post, but I just connect the usb stick and then it asks me if i want to use it as a storage expansion
[Android Head-Units] MehdiNdj:
Thanks for your reply.

I checked on CPU-Z and the only reference I found was 866X. I also got a reply from Junsun sending me this firmware:

8667Q军灿UI02-国外-1280x720_v48_20231201.zip

drive.google.com

Junsun told me it's UI 4.0 (even if the file is named UI02.

I hope this firmware will allow me to get fewer Carplay connection problems. Because about 1/4 of the time, my Carplay wouldn't connect and I had to ignite my engine again for it to work.

I don't know if anyone else has this problem with Autolink and Carplay?
[Android Head-Units] TorstenH:
I think you should ask this question in a thread for 8667 units to get an answer related to your device.

Hi everyone, I have a Junsun 8 core with Andoid 13, I would like to update the firmware, but I'm afraid of losing wireless carplay, can anyone help?
[Android Head-Units] ipio:
Hello, I have a few issues and questions regarding my radio. Unfortunately, the person who sold it to me is not responding to any inquiries. So, in mid-2023, I purchased a radio, exactly this model (https://www.junsun-china.com/junsun...ar-multimedia-gps-dsp-autoradio-p00288p1.html).

Currently, I have a problem as I have configured something and don't remember where, and the radio requires my phone to be connected via Bluetooth and Wi-Fi; otherwise, CarPlay won't work. I would like to have it as it was, only through Bluetooth.

Another issue is that when I connect Autolink, Spotify plays, but sometimes it stops after a song, and I have to skip to the next one. I wanted to update the Firmware, but I don't know how to do it. Can you provide guidance or point me to any tutorials?
[Android Head-Units] TorstenH:
Install CPU-Z and check if you have a MTK825X device, first.

Carplay and Android Auto require an USB or a wifi connection. It's not possible with Bluetooth-only.

An no, you don't have an Android 13 device because the shown version is faked on all Junsun devices.

Thank you again.

I will try the proposed solution.
[Android Head-Units] ipio:
This?
[Android Head-Units] TorstenH:
Excellent. It's a Mtk825x unit and so you can install the latest firmware from first post - at least if you don't have a BMW or Mercedes with special input devices like iDrive.

Why is the v113 not listed on the first post? Is there an issue with it or is it just an omission?

I added it. But I never tested it because I don't have a Junsun unit in meantime. 😉

Hello I installed cpu-z and verified, my question is now I lose the autolink license if I update the firmware?

No, your will keep your licence because it's getting stored on a separate partition.

But keep in mind: you're doing everything at your own risk. So don't blame me if something is going wrong.

Hi all, i would like some help please.

Unit: Junsun v1 plus 6-128

Car: Renault Clio 3 Rip Curl 2007

Problem: steering wheel controls dont work.

Can bus adapter says SW: RN v1.4 102byps.

On unit settings code 8888 can version is 101 byps. Please Check photos below.

can this be the problem? Can i "upgrade" to 102 byps?

The original clio display is connected and working fine.

From the original clio radio i have two cables which i dont have where to connect on the Junsun Unit. One has a yellow connector and the other a blue one. (I can post fotos of those connectors if needed). I think one of them is from a usb + aux unit that came inside the glove box. Can the other one be related to the steering wheel controls?

Can anyone please help?

Thanks in advance.
[Android Head-Units] ipio:
I do it but i get the same error
[Android Head-Units] TorstenH:
Have you tried to flash the latest firmware to see if can version changes?

But please be aware that it looks like you have a 8667 unit and you can't use the firmware from this thread.

Alternatively you could try to use a modified MainUI.apk.
[Android Head-Units] mfpower86:
Hi, hope youre doing fine and thank you very much for helping.

Can you tell me what is the latest firmware and\or mainui.apk for my device? I spent the last few days reading on this forum and watching YouTube videos but theres too much information to filter.

The unit came with firmware v41.

I tried v5 but didnt like it, a few things did not work. Including the steering wheel controls.

Than I flashed v46. Everything ok, but steering wheel controls still does not work.

All the downloads were from this fórum.

I also tried a can bus updater app.. but also did not solve the problem.

The seller is not supporting much so, thanks one more time.
[Android Head-Units] TorstenH:
I've sent you a private message because I don't want to share fw links in this thread that are not related to MTK825X.
[Android Head-Units] mfpower86:
Sorry for posting about v1 plus on v1 pro thread, im new to this kind of car head units, already learned a lot from here so thanks a lot to the community and in particular to @TorstenH who helped a lot.

[Android Head-Units] joaomPT:
Hello everyone.

Sorry for the big bump on my own message, but it's just to serve as context of my big headache with Junsun.

I have a Junsun V1S Pro headunit, with firmware v63 from 2023.

My headunit is Carplay Wireless compatible, as shown on AliExpress page, however, the seller says that it's not compatible with Wireless Carplay.

I cannot use AutoLink wirelessly with Carplay, because the only icon available is Android Auto.

I've attempted to register a different code, but it doesn't change anything

I've attempted to remove the .txt licence file from the sd card as "dansblackcat" said on a previous post

"(...) The licence file is stored in the main directory of the internal SD card. I forget the name of the folder. (...)"

But nothing works. I'm stuck with this image below, on my AutoLink. It's been a nightmare and a huge headache. I just wanted to remove the current license or something and try a different code because I'm pretty sure that my head unit is activated with Android Auto code by seller's own mistake..

I've contacted them again, but I don't know what to do anymore.

Can I somehow remove the current licence, completely? Making it unregistered again permanently, because the radio keeps re-activating again even if I clear app storage, reboot, etc

If I can't get a fix on this, I'm changing head unit
[Android Head-Units] joaomPT:
Based on my previous post above, can I do something about this?

I wanna reset my license, because I can't use wireless Carplay for some reason

P.S: Sorry for double posting, but I don't know how to quote on the same post :(
[Android Head-Units] joaomPT:
** RE-ACTIVATE NEW CARPLAY LICENSE FIXED - Tutorial here **

After 2 friggin years, it's finally done!

Junsun seller support on AliExpress is completely useless and horrible, as I did try to get help from them multiple times during the 2 years time-span, and all they were telling me is that my radio is not compatible with Carplay Wireless, bla bla....

Fun Fact: Junsun seller gave me the wrong activation code the time that I bought the head unit, I asked for Carplay and he gave me Android Auto....

Anyway, on this link, has a guy saying that he activated the wrong code on AutoLink, and managed to fix it.

I followed his instruction, and it worked!

Install SpeedPlay apk, attached to this post (it's one of them, but for me SpeedPlay_base.apk worked, the other wasn't installing) then I simply placed the right code this time (yes I did have to buy a second Carplay Code and then boom, worked.

Finally this crap is working, but thing is for sure. The lack of support and lack of care from Junsun brand, makes me not wanna buy any head unit from them ever again.

Hi

I'm trying to update my MTK8257 firmware from V63 to V107 (8259P_军灿UI02v1280x720-国外_v107_20230919) (because im insure if V113 has been already tested)

Then, when I put my USB Pen into the head unit, it prompts the Update popup, reboots with green "success" and below in red "Failed. Check usb and files"

I come back to my pc, Windows says my usb has a problem and to fix it, and when I open it up, it has the "Android" folder inside.

Could this be the reason why I'm unable to update?

Last time I updated, it was summer last year and I don't remember if the head unit was creating the folders and all that.

It was with this same pen drive, and everything went smooth back in the day.

If it helps troubleshooting, I have 2 explorer apps installed (in case they're messing with sth)

Any idea how to fix this? Thanks
[Android Head-Units] gduck:
Don't worry about the Android folder. I think your USB pen format is NTFS! Please, format with FAT32 filesystem and repeat the update! ;)
[Android Head-Units] joaomPT:
Good point

However, my Pen is already FAT32 with default cluster size 😅

Attached the 2 imgs I told before

EDIT: Hmmm..... I went to my old post, and last time I had this, I was trying to install a firmware that is not compatible with my HU radio.

But this current one that im trying to install, apparently is?

Hello fellow JunSun People,

first of all, wonderful that there is a site specially for JunSun devices, appreciate it a lot.

Kudo's to the founders and Mods.

I have an issue with my Junsun V1 Pro 4gb, i recently bought it (2 months ago).

I want to upgrade the firmware, which usb stick i use doesn't matter because it wont start the firmware upgrade...

I have downloaded this file for the firmware upgrade:

8259P_军灿UI02v1280x720-国外_v113_20231122.zip-Tan

The usb sticks are formatted as FAT32.

I unpacked the 2 files and put them in the root of the usb stick, when i attach the usb stick to the junsun the update wont start.

The name of the 2 files are: 8259.upd and 8259.bin

Filemanager can see and browse the usb stick, but no start of firmware update.

Is anyone formiliar with this problem i have?

See attachment pics for clearance...
[Android Head-Units] TorstenH:
I don't think you habe a MTK825X device and so the firmware isn't compatible.

Hi guys!

I've a 1280x720 junsun 8259 pro, but with ui 3 at the lastest patch (113), can I upgrade to UI 4.0? Even if the resolution is bigger (1920x720)?
[Android Head-Units] gduck:
Hi!

1. Check your current firmware first! UI04 is only a THEME, maybe you have already have it. ;) More info: HERE

2. Check your current firmware version in the Settings/Car infotaintmet/About device menu, with code 160!

If you have 1920x720 firmware, DO NOT use 1280x720 firmware! And vice versa. ;)

What is your current firmware version?
[Android Head-Units] hurjup:
Be careful, by my latest knowledge the UI 4.0 themes do not really match the stock photo ones; around v81 they were f****d up really bad. At least I am ware of these for the recent firmware revisions, didn't try v113 though.
[Android Head-Units] Simos805:
Junsun V1 Pro here Can anyone tell me if I have the latest firmware? and if not, should I update it?
[Android Head-Units] Pepebak:
Is there any firmware for our devices (MTK8259) with UI03 or UI04, and why doesn´t exist it? I don´t understand, are there anybody who knows about that?
[Android Head-Units] gduck:
Hi!

For example this is the V113 with UI03:

I attached the v113 manual.
[Android Head-Units] gduck:
USE code 160 to check your actual firmware (see the previous posts)!

Anyway, I think, you have: 8667Q军灿UI02-国外-1280x720_v39_20230712

This is a good firmware, if you don't have a problem, don't update it.
[Android Head-Units] Simos805:
It is on 5Ghz on mine but CarPlay isn’t the smoothest thing I have seen. For sure not as smooth as the rest Android UI.
[Android Head-Units] Simos805:
Yes! I checked the firmware right now and it is the same one you mentioned. I don’t have any significant problems, but for example I want CarPlay to be smoother… Also I forgot the fact that almost all the settings are reset to default every time I restart the unit…!

As I can see I’m on UI 2? And there is UI 4 right now? Are there any risks updating the firmware? Also is there one firmware version for everyone or it has to be a specific one ti support my car canbus etc?
[Android Head-Units] gduck:
Hi!

If you would like, you can update the firmware without any problems. Please beware! All additional content (your music/photos, installed applications, etc) will be deleted during the update!

Don't be bothered by the name UI02, (this is containg UI03 and UI04) I don't see the logic in it either :D Please see this post ;)

In the UI02 "JUNSUN firmware family", the v48 is the latest public version.

8667Q军灿UI02-国外-1280x720_v48_20231201.zip

This is newer, contains UI03 and UI04 THEMES. Please, read my old post HERE ;)

8667Q军灿UI03-车模--1280x720_v5_20240113.zip

But, you can update the Carletter without update a new firmware.

CarLetter_v5_latest.zip (Note: the app "external"name was changed to PhoneLink. But in the About, you can see: CarLetter :D )

Please! DO NOT USE the factory menu for restart the device! Install this little app (attached) and use that! ;)
[Android Head-Units] Simos805:
Thank you! Have you seen any other noticable changed between those firmwares? I read on another post that one user updated the firmware and CarPlay became more laggy. If I encounter problems after the firmware updates, can I downgrade back to the current firmware of the head unit and the CarLetter app?
[Android Head-Units] gduck:
Yes, you can revert to an older firmware version at any time.
[Android Head-Units] Simos805:
Tried to install the updated firmware but it shows this after the first reboot and then boots again in Android without installing the update. Any ideas?
[Android Head-Units] gduck:

[Android Head-Units] Simos805:
Used an old USB 2.0 drive and it worked! The firmware is installed. Right now I think CarPlay is smoother, but not by much.

Also I installed the fix for the open door indicator and I activated the 360° Car app, but its not have my car model… I have a Renault Clio IV. Is there a way to import it somehow?
