Okay i have the same MCU version but not VHD, its only HD
I'm not sure if that matter or not unfortunately.

But the way I got it, I annoyed the customer support of the Junsun france store for about two weeks, then I opened a dispute, after that they started to take me seriously and contacted an engineer, I told them what was wrong, and how should they fix it and they did. Took them 2 day and they sent me apperently custom mcu update for me which fixed my issue. So maybe you should contact them too, tell them about how they handled it with me and they will hoppefully help you too.

Hola. Soy bastante nuevo con la unidad Junsun v1 Pro. ¿Es posible cambiar de alguna manera la aplicación de música predeterminada (not radio FM) a Powerpro, por ejemplo?

Hello again. Could you tell me where I can download the .zip for launchers?

There is one post with the launcher zip file. But the first post may be interesting for you, too.

    @TorstenH I know you app very well :) Nevertheless after the restart I found the installed apps, so all is fine. With v94 also Android auto works well. Only issue is, I have to find, how to keep the settings (display brightness etc.) also after reboot of the unit. But I'm pretty sure, I'll find the answer in the forum. It's 5 year since my last unit installation :)
    Anyone got any idea how to use an existing DAB antenna with this unit? I have been recommended a 'USB DAB adaptor' that comes with it's own little antenna.
    You can connect those USB DAB receivers also with an existing antenna. You just need an adaptor to connect your existing antenna.
    Here one example for a popular DAB receiver with a MCX connector:
    Sure, the other side of the connector need to fit to your car.

    Here for your reference:

    HI Alternativ,

    can you explain me which step you did to change the appearance of the aircon screen?

    Thanks in advance
    In the factory menu, in my HU 8878, there is an option to enable the appearence of the AC topic on the regular settings menu like the image on tis post:
    You have to choose enabled an save on exit from the 8878 menu
    In my HU I press Settings Menu, then I press "Infotainment Car" (photo1) then it opens a new page and in Video Section see (photo2) there is an option Ar Condicionado (Air Conditioned) "Fora" means OFF, that is what you need. Hope it helps!
    Thanks @Alfarroba

    I was able to get rid of this annoying air screen following your instructions!
    Ok, Thanks! So I have to ask for a device replacement with the correct...
    V1 Pro is now V1 Plus they changed the name

    Hello I recently bought a Junsun 4g + 64gb version, and I'm having some trouble.

    On my unit sleep mode doesn't work how it's supposed to, after about 30minutes when I try to start the radio it will long boot I would like to set it to 3day like I had it on my other junsun unit but there is no option like that, only on and off. I checked the wiring and red and yellow cables are connected right.

    Also I was wondering how did you guys make the settings menu in dark mode, i tried to force it through developer mode but that did not do nothing.

    I received a MCU update from Junsun to fix my sleep issue if anyone is interested
    MCU before : MCU: TS-G5.201021(VHD)
    After : MCU: SS-G5.230529(VHD)

    Untested but may work:

    Put the logo on the root folder of an USB drive by naming it

    Enter factory code 5678 and plug in the USB drive.
    Thank you. Succeeded, I copied the image to the USB Drive root folder. The correct size is 1280x720 and can be .BMP or .PNG format, the file name can be anything.
    But maybe you're interested in my new free app:
    Are there any other codes except 8888,8878,8877 to try?
    Use at your own risk !!!!

    8888 - restricted settings menu
    8878 - full settings menu. Mostly what you're looking for.

    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.
