Instead of updating the whole system an update of the core application MainUI may be an alternative.

It is installable by downloading it from here

https://xdaforums.com/t/appswitcher...-devices-incl-autostart.4593865/post-88620949

Additionally you have the possibility to use AppSwitcher to enrich your SWC mode button.

Let me mention that it's also possible to update AutoLink by installing the apk.
[Android Head-Units] TorstenH:
It helps to have the pin description of your original radio. I think a car from 2001 provides the reverse signal on a dedicated 12V+ wire and is not related to CAN.
[Android Head-Units] Spaqx7:
Hello everyone, I'm looking for help, there is a junsun v1 pro 4 64 radio tape recorder, it does not accept a single flash drive, does not respond to firmware, how can I flash it with another method?
[Android Head-Units] TorstenH:
Please note that the Junsun firmware version numbers (v90, v94, ...) are not related to the OS version (build number).

Sometimes the Chinese just change or add some apps or configurations to support additional CAN boxes or other functionalities by keeping the OS as it is. Nevertheless they count up the version number.

The Chinese are manipulating the OS to show you a faked Android version.
[Android Head-Units] Alfarroba:
@TorstenH Have you give up the Carletter activation/functionality?

Otherwise how can we unninstal the carletter app we have installed during your nice experiment?
[Android Head-Units] TorstenH:
In meantime I finished a AutoLink experiment which activated the app for Android Auto and CarLink (both wired and wireless).

Regarding CarLetter I figured out that an additional system service is required. This service is available on firmwares >= v90. To get it running further analysis and tests are required.

Which firmware have you in place?
[Android Head-Units] luiyibike:
Hello, I factory reset my Junsun v1 Pro 6-128Gb and now it asks me for an activation code for CarPlay. The manufacturer says that it does not need a code, can anyone help me?

automatic connect bluetooth every time I turn off the radio it appears disconnected. Why could it be? so the bluetooth does not connect automatically and I have to do it manually
[Android Head-Units] TorstenH:
Is Bluetooth completely disabled after reboot/sleep or do you want your head unit to connect to a bluetooth device?

Usually your phone needs to connect to your head unit - not the other way round.
[Android Head-Units] luiyibike:
If I check that option when restarting or suspending the Junsun radio then it appears disabled. Bluetooth is required to use CarPlay.
[Android Head-Units] TorstenH:
You can't see the Bluetooth icon on the status bar?
[Android Head-Units] luiyibike:
Yes I see it but my phone does not connect automatically so I thought that was the option that had to be turned on. But I don't understand why when turning off the Junsun that option is not checked?
[Android Head-Units] Alyer777:
Hello there,

Anyone know if Junsun UI 4.0 is out for V1 pro ?
[Android Head-Units] TorstenH:
If you can re-establish the connection by just using your phone, without turning on an option on your head unit, you should check the settings of your phone.
[Android Head-Units] Alfarroba:

Buenas tardes karlos937, tengo el mismo problema que tu. Conseguiste solucionarlo. Un saludo
[Android Head-Units] brainwash123:
I meant that the seller implies that out of the hundreds of sold units, none of them had this problem. I think you misread the years I wrote. Also, canbus is much older than 2005.

My car is from 2010, there are no additional wires, everything is done through canbus. I attached the pinout here: https://xdaforums.com/t/junsun-audi-head-unit-reverse-camera.4617559/#post-88897011
[Android Head-Units] ndwuming:
:cowboy::cowboy:good
[Android Head-Units] TorstenH:
Every (Chinese) seller would say that just to get rid of your complaints.

That's not a pinout but just a schematic of the plugs and sockets. Nevertheless you see the "Reverse trigger line" which needs to be powered by +12V to let your head unit switch to reverse camera. Just because your car has CAN doesn't mean everything is managed via CAN. If your car was shipped without a reverse cam you need to install one and lay a cable from the back of your car to the head unit to provide the video signal. Usually those cables have an additional wire which can be used as "reverse trigger".
[Android Head-Units] luiyibike:
How do I configure this step?
[Android Head-Units] TorstenH:
I don't understand how you can use your head units without AppSwitcher? Or do you all have always a copilot who operates the unit for you while driving? 😅

Without AppSwitcher I would throw my head unit out of the window. And it would depend on my mood if I open it before.
[Android Head-Units] brainwash123:
You are right, that's the wiring diagram for the aftermarket unit. There's no point in attaching the pinout for the original unit since it doesn't have any special wires: https://pinoutguide.com/Car-Stereo-Audi/Audi_A4_B8_2008-2012_Conc_pinout.shtml

The car can have a factory-installed camera, which mine doesn't. I can activate that option through VCDS but that's beyond the scope of this topic and it doesn't change anything. The aftermarket unit (Junsun) has the option for factory camera or aftermarket camera (several type) and is obviously set for an aftermarket composite camera. The factory unit receives all triggers (SWC, PDC, RVC, lights, doors, etc) through CAN.
[Android Head-Units] _Tremen_:
Good question, can you use another rom other than the one provided by junsun? It is that when selecting the canbus my car does not appear in the RAISE, my car is an astra k
[Android Head-Units] TorstenH:
Do you have the pinout of the factory head unit which gets sold when buying your car with reverse cam?
[Android Head-Units] Vibez66:
Hi

I have stupid question maybe... I bought Junsun from aliexpress and in descriptions was Android 12, in reality is just Android 9 PIE :( now i cannot install some aps what i want...

My question is can i install new Android there?
[Android Head-Units] TorstenH:
Here is an example of an Audi head unit with CAN. Nevertheless the "Reverse" info gets transferred by a dedicated wire:
[Android Head-Units] PrinceLc:
Ask Xtrons they have the same units and hardware
[Android Head-Units] DenisBeljata:
Maybe this topic is not the correct ones, but I have an issue with AutoLink.

There is no problem to connect the phone by wireand almost automatically starts the WIZE.... All was good, until I've updated the Wize in the head unit.. Now everything works, but have no Sounds / warnings from Wize.

Any halp will be appreciated.

Hello,

If I download the version 8259P_军灿UI02v1280x720-国外_v94_20230729.zip, it will work for BMW with resolution 1920x720 after changing the config file?
[Android Head-Units] TorstenH:
You should try that only if you have the possibility to re-flash the firmware you're currently using.

At least I know that for BMW Mini devices the core app MainUI is different.

Even the latest v94 is only Android 9. So a "just for fun flashing" is not worth the effort.

You flashed a firmware which is not pre-configured for your device. A reset would not help.

[Android Head-Units] Chernesto:
Hi,

I use many links on your forum. And update Junsun v1 Pro with v90 and also v94.

I use CarPlay wirelessly every day. But with the v94, It won’t open Carletter and it stuck on the authentification page.

I use the carletter apk of TorstenH with the prop file and it works well with sometimes some disconnect/reconnect with the v90.

With the v94, I can’t use it because the apk is older. Can you please upload the carletter update apk activated like you did for the v90 ?

I install it with the 0.21 mainui updater like you said on the page 45.

Good evening everyone, I'm new to the forum and I don't speak English so I rely on Google for translation. I bought a Junsun V1pro 4/64gb about a month ago for my 2014 Peugeot 2008 HDi 1.6 Allure with canbus. Everything seemed to be fine except that I don't see the external temperature on the display as it happened with the old support. I asked the seller but didn't get effective help. Can anyone help me. The other problem is that although I have the "remember" option set, after a few restarts of the carplay I find myself with the music on. I am attaching some pictures which I hope will be helpful. How do I see what firmware is installed? Thanks in advance for your help, and my compliments to all of you who try to help people like me.
[Android Head-Units] Vibez66:
U know that its not Android 12?
[Android Head-Units] TorstenH:
The remember option only starts core apps automatically and Music seems to be the last core app you used.

You should turn off remember and use AppSwitcher instead...

If it stays flipped you can change orientation in factory settings (code 8878, section Others).

Hi, my friend buy android multimedia, he wanna know, how he can enter in canbus settings?
[Android Head-Units] brainwash123:
Hmm, did not look for it. But the parking sensors view gets activated on my original unit, without any extra wires.

Managed to 'solve' it in another way: took out the PDC switch, traced the PCB and found a wire which is activated with 12V when PDC is active. Took this wire to the junsun unit. From the junsun unit, there is a camera 12v output which seems to only get activated when the RVC signal is on. Hopefully it's a switched signal and not just a short between those two wires. So now the aftermarket camera works as intended.

Hi everyone, I own a Roadanvi F10 unit for Peugeot 208 2015. It has the same chipset (MTK 8259) of the Junsun, but I really don't know if it's possible to use the Junsun firmwares in this unit. I think the answer is no, but I can't find any information here nor anywhere else.
[Android Head-Units] TorstenH:
Extract the firmware files (upd and bin) on and usb stick and plug it into the 4 pin usb of your head unit. If the firmware files getting recognized and the head unit asks for update give it a try...
[Android Head-Units] blak24:
Thanks for the reply. I may try, but is this operation "safe"? I mean, nothing is safe while flashing a new FW but if there's the risk of an incompatibility and to brick the unit, I may reconsider this.

Anyway, just a few questions:

1) which version may I try from the open post, the one with the highest number?

2) what do you mean by 4 pin USB?

Thank you!
[Android Head-Units] TorstenH:
There is a risk and you do it at your own risk.

Highest because all the versions are just Android 9.

Compare the USB wire sockets on the back of your head unit.

Will try anyway this morning as soon as I go to work.

@TorstenH I'm going to try the app you suggested, thank you! In the meantime, just a few more questions:

- is it possible to change screen resolution? In the factory test menu I saw under display settings something like 1024x600, but the unit was advertised as 1280x720. May I change the resolution in the same menu? Don't know if it may cause problems

- is it possible to do the same with the auto link app for Android auto? I mean, I would need a DPI change, but maybe it's a consequence if I change screen resolution

@TorstenH since blak24 succeded updating the fw on an HU like mine I was thinking to do the same.
