I just received a reply from JunSun support that it's not possible to connect Internet through Bluetooth in the unit. The only option is mobile hotspot after all
They told me the same thing and it's not true, I can do tethering by bt. I copy and paste from a post that I put pages back, I hope it helps you.

My headunit is a kapud mtk8257, but it is very similar to Junsun V1 Pro.

In 90% of the cases, if before connecting the bluetooth on the mobile I am already allowing tethering (phone) automatically the headunit picks up the internet from the mobile.
But other times I have to force it: the button is "hidden", once connected to the phone, go into settings, click on the magnifying glass/search engine, look for "previously connected devices", click on your phone, and you will see that one of the buttons is "allow internet connection" or something similar.
PS: I have the radio in Spanish language, but the name of the menus should be like this, or similar.

On Junsun V1 Pro with MTK8259 CPU it's definitively possible and so I created the app to be able to reach the corresponding Android setting directly.

The Chinese don't know their own device or are to lazy to give detailed information. They told me that it's not possible to show the Android status bar on top of apps installed by customer. And that's a lie, too.

Greetings, I have a small inconvenience. On two occasions, it randomly happened that the settings and the saved radio stations were deleted. I also found users on the net who are also struggling with this problem. Can you suggest a solution? It's not that disturbing, but if there is a solution, I'll gladly apply it.

Hi,
I own this model and by mistake some days ago I input the 9191 code ( destroy_id_root_num ).

Now I have the red text "device not activated" always on the screen.

I already upgraded it to the latest FW found above and the upgrade completed flawlessly, but the device still didn't activate.

I find out that the solution is as simple as to have a small file called "licence.dat" to be put on an usb stick and an internet connection.

this file contains only a small string of text.. something like

dUtXM3NyL0d2THdqUmtaTFNnPT0jMjAxODEyMDYwOTQ1NTQj##*161

( the above is for a 8227 device and didn't work )

Has someone here the needed file.. or even just the text string and I will edit the file by myself ?

or do you know some other way to solve the issue ?

;)

- This is the code for my variant Jusun 8259 , V1Pro 4GB\64GB\WiFi .

- dmZERXpiS3BJMHBPUWs4PSMyMDIwMTEzMDEwMjQxNyM=##*10000

- Read befor Acct: The Chinese technician asked me for a picture of the back of my device. Probably to make sure of the version I have. I posted the picture for those interested. I warn that the code should be written in Notepad format and the stick should be FAT32 formatted. I have also posted the film sent from China as well as the video I took unfortunately after the procedure. For me, things went more simply than what is seen in the Chinese one, that is, I proceeded exactly like this: After Fat32 formatting the stick and copying the code, with the device turned off, I inserted the memory stick into the USB 1 port, then I turned on the device, it opened (in my case) the loucher AGAMA and the window with options in Chinese appeared. I left it waiting without giving any command, and after 10-20 seconds another window appeared automatically with another inscription in Chinese, then the device turned off by itself and reopened and I found that I got rid of Device is No Activation. I want to point out that I have 4G with a SIM card, so the internet is permanent. In order for the procedure to succeed, you must have the device connected to the Internet, have a Hot Spot or Wifi. Otherwise, the procedure will not be successfully completed. I wish you patience and success.

Hi friend.
Did you resolved this problem?
Thanks
Hi
⦁ Prepare one USB disk and format it, copy all the firmware files to the USB disk, insert the USB disk to USB port.
⦁ Turn on the Android radio;
⦁ Please find a sharp stick to clik RST hole.
⦁ When you see Car logo on the screen, please ignition off and take out the key.
⦁ 5-10 second later, ignition on again, you will see green letters (update start) on the screen.
⦁ Wait for upgrade finish. Take out the USB disk and reboot the unit.

Hello guys,

I have a problem with Junsun V1 pro 4+64 radio that I recently purchased for my Golf mk6.

It is working fine but it is really, really slow.
Especially with google maps or youtube.
It feels like a 5yo mobile at least.
Everything is just lagging, no smooth motions, loading very long etc.

I've already tried factory reset, data cleaning and updating apps. Average RAM usage is under 2GB.

Has anyone of you faced similar issue and knows how to get rid of it?

Thanks :)

average ram is under 1GB I bet because your radio does not have 2GB or 4GB it is hardcoded number, actual RAM is 1GB shared with OS. There is only one solution for your issue. get your self better radio from reputable brand

bro, my friend has the same radio for Impreza GH and it works perfectly smooth. However, he has 8+128 version so I don't want to compare them directly.
Anyways, it seems like the other users of 4+64 version don't complain as much as I do so it must be something wrong with this particular one.

I have 2+32 and it is crap slow, plus the RAM never goes above 1GB which makes me believe it is just 1GB RAM radio even though it shows 2GB

Can you please share the "About Device" screen. Also any informational screens from cpuz, devicecheck, etc since it was observed that the system reports it is Android 12 . Thanks in advance.

Update: I managed to install this software on my Eonon 4gb/64gb unit (hw similar to Junsun) and glad to report it runs very well. Yes, it reports Android 12, but is really Android 9. It launches apps fast and smooth. Wired AA works flawlessly, so far.....

Hello,
I have the same Junsun V1 Pro, but I have a problem updatting..
It doesn't do anything when I insert the USB stick in my car. I already tried with many other USB sticks FAT32 formatted of course.

The first time when I bought the Junsun, I managed to update without problem, but now even if I do the same way, I cant.

It is recognized by the Junsun, but the update pop up doesnt come up.

Edit : (I've just downloaded the latest firmware posted by hackras (thank you), I'm gonna try within 15mns, even though I have no hope)

Any clue ?
Thanks!

    Tell us how,the steps we must do
    Download image you want with good resolution. Use online pictures editor to make it 1280x720pixel and bmp type. Upload to Usb drive and put USB in the media. Then enter boot logo menu, tap search and will see it.

    Firmware installed in meantime?
    Today I applied the Firmware Stock update procedure. The procedure was successful and the tablet works ok. It remains to put it back in the car and see how it behaves in tests. This was possible for the two users who thank them once again: djborsi and TorstenH. I removed the tablet from the car and made the connections to be able to work with a + 12V DC / 220v power supply. For those who want to power it separately from the car, I put some pictures after the procedure and a wiring diagram. I made a video with the FW update procedure. Because I noticed that the tablet heats up a lot, I mounted a 12V / DC fan, It has the size 70X70mm. and thickness 15 mm. It was from an old CPU cooler. It is fastened at the back with 4 screws as seen in the photo. I put a 40 Ohm series resistor. to reduce speed and noise. I hope that what I posted here will bring a little help to those interested.

    Hi,

    here my experience with Junsun V1 Pro with MTK 8259 (detailed spec. of device in below screenshots).

    1611240722227.png
    1611240746293.png


    My car is:
    Mazda 3, produced 2010 (type BL).

    1. The radio station memory is cleared after rebooting the device (i.e. after setting differen CAN Type), so I must always to set the radio channels from beginnig on.
    >> this I can handle since I don't have to play with CAN Type setting all the time.

    2. I cannot pin any widget, or any shortcut of an app the to any of the home screens! The system hangs up when I trying to pin something.
    >> this is to solve by different launcher. I have tried with Nova launcher and took radio, bleutooth etc. app from “for_launchers” zip file. Was working fine.

    3. During using a navigation app the music from radio and sounds from navi are not mixed. Radio is playing and when navi sound comes, then radio is reduced and overplayed, I couldn't find option to change it.
    >> in the end nothing special, it is a matter of expectation and taste.

    4. The reverse camera (gift from Junsun) is not working afer installation according to diagrams.
    >> this stays unsolved...

    5. After switching car gear to reverse any backview as Warning Line or as Assistance Line are not working, not appearing!
    >> is unsolved,
    maybe connected with issue no 4. (system doesn't detect camera, so also deosn't activate any backview).

    6. After switching car gear to reverse the sound level reduction deosn't work!
    >> is unsolved,
    maybe also connected with issue no 4. (system doesn't detect camera, also deosn't activate any backview, so in the end no sound level change).

    7. I did Reset to Factory Settings (through android interface) to correct the problem no.2 (see description above). It helped for a moment, so after some time (~15 minutes) the issue came back, so still I cannot pin any widget or shortcut to any home screen.

    8. I cannot find any option to make Screen-Lock.
    >> probably dedicated app would help, but I haven't tried.

    9. The CAN info are not working with my car, so I cannot see any info about open doors, etc.
    >> I was using CAN Type 145, as adviced by seller, but still was not working.


    All of above issue I was trying to solve with seller via messages (my english is not perfect, but their ... terrible).
    After upgrading the device to a new FW (provided by seller), after few days of discussion, I have decided to return the radio back. I did all according to agreement with seller and via aliexpress system and it worked fine. I got money back (211€) , all good.

    The device, beside above described issues, worked really really well, fast and smoothly.
    The GPS was catch fast and 4G with sim card slot extension worked really amazing (direct internet access as well as direct phone calls possible!).
    The radio reception and the sound quality, also very good!

    It is a pity, because the device looks like has a big potential, but the current FW is not perfect, so causing small, but many annoying problems.
    Not sure about camera issue (no.: 4+5+6), if it is connected with FW or rather with CAN decoder...

    I would consider to buy it again, but first I will wait for a better FW/OS/ROM, so I am looking forward for any news about it!

    I hope the info will help some of you.
    Greetings!
