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.
When enter with code 8878 in boot logo menu shows car logos from different manufacturers of cars.that is what you have changed or the "android" logo?

Week using Junsun V1 pro 4GB
Really like it, it works good.
Cant remember all settings good but nothing fatal.
It is really strange some things but...that is it.
When turn off car, unit go to sleeping for maybe 16-20 hours. Then the unit turns down. On resume after sleep remember all, but apps are closed. After cold start remember all , only icons on the home screen are default.

Просто инсталирайте Junsun v1pro 4gb
Просто искам да знам няколко неща
1. Мога да накарам приложението за телефон да използва контакти и да извършва повиквания само от SIM картата на моя телефон, свързан с Bluetooth, а не от SIM картата с 4G модул. Искате да използвате 4G SIM в слот само за интернет

2. Как да настроите вратата да се вижда отворена

3. Как да кача моето лого -Bootlogo has changed when put bmp image in usb 1280x720 tested-works

4. Както и да е, за да направите по-голям часовник, когато някое приложение е отворено

5. Мога ли да променя лявата страна на началния екран {това с кола и скорост)

6. Колко време е в режим на заспиване, преди да се изключи. Нямам настройки за това. Какво ще кажете за моята батерия?

7. Някои необходими настройки в тайното меню (това с код 8878) или някои интересни опции там. Просто не знам повече от тях какво наистина правят.

Всяка допълнителна информация ще бъде полезна.

Hello. I'm a new user with the junsun v1 pro.
My question come because I've got a Seat Ibiza 6j from 2014. And having problem with can bus type and swc. Can't detect any button but volumen +/- works , but isn't saving any button.
I want to add that reverse gear, makes the screen off. Tried the advice from the seller to set the flag from can type hood to off. But doesn't work either. In summary I think they gave me the wrong can type for my car.
How I could find it. Thanks.

Attached images, with software version.
The number they told me was 122 can type but even sometimes after reserve gear shows this image, regarding and fake open bonnet!??

Is it possible to turn off hiding the top bar when starting waze?

I went through the thread and didn't find an answer anywhere, I might have missed it.

Re-Hello :)

Does spotify / YouTube sound coming from Wireless Apple Car Play (with the AutoLink) sounds like it has little less quality ? Like just a little bit, it sounds like to have more high frequency vs when i am using bluetooth only and not CarPlay.

It’s not annoying but i can hear it.

Am I the only one for this issue ?
How do you connect CarPlay via wireless?

Hi All,

After weeks of trying to get used to it, I'm pretty happy with the device, even with the minor issues.
Currently I have two main problem, hope someone can help:

- The saved radio stations get reset every few days, and happened twice yesterday actually.... Any way to fix this?
- I'd like to run a few apps at launch, such as a firewall to allow only the apps I need via my limited bandwidth. Also Torque at some point. But every time I turn off ignition and turn back (properly wired), these gets shut down. Is there a way to stop the device shutting down these apps?

Btw, I was not happy with the Junsun camera, too narrow view. I installed this, and works great with the unit:
(I had to select AHD 720p / 30 fps).

steering wheel controls!

Hi all, I'm having a doubt with my junsun v1 pro.
I have correctly installed the steering wheel controls, and when I press the voice assistant button, the android car radio voice assistant automatically starts! But that is not suitable for infotaimant commands. Does anyone know if it is possible that the voice assistant button can activate the nexi voice assistant? or that of the mobile phone via android auto?

First provide name, type numbers and photos of your original OEM radio to have a chance to find a pinout chart. Maybe there is no need to use a can adapter to use the SWC. Often a radio labeled with "Alana" is used on Seat Ibiza...

Does this happen when you change something in the menu with the 8878 pin? I read it somewhere that just because it prompts for reboot, you don't have to do that. Just go to the main screen. It works for me.
But indeed, it does forget some settings...

    I haven't checked, nor do I have a multimeter handy.
    Just checked, only supplies 12V when in reverse. However with this setup (removing the 12V from the cigarette lighter), the camera still has a delay of about 10 seconds whilst the boot logo is shown.

    Hello guys,i installed a rearview camera and i can t figure out how to make dynamic lines when i move my steering wheel.i contacted the seller and he is telling me i need to buy another camera,If anyone can help?Thank you
    Dynamic lines will only work if you connected a canbus box. It has nothing to do with the camera.

    Exception: Some cameras are "painting" the lines fixed on the image. Those can be removed by cutting a wire according to the manual of the cam.
    1
    The 12V wire comes from a two wire harness connected to the head unit, it's a pink wire along with the reverse camera RCA connector.

    Here's the back of the unit and frame, see the reverse camera RCA connector and the pink wire that supplies 12V.

    I don't know about the brown wire; mine is not labelled. There's another photo when I was figuring out which camera connector to use, can you see the correct brown wire from that?

    (I assume the CANBUS module or a wire on the car harness provides the reverse signal to the head unit)
    So the pink wire supplies the camera with a constant 12 volts, the canbus is responsable to switch the head unit to display the camera video, and at the rear of the car you only have connected the RCA cable to the camera, with no 12 volt connections at all?

    View attachment 5439269

    I have one problem with reverse camera when I put on reverse the car ( toyota rav4 2010 ) nothing happens, the reverse cable gets 12v but the reverse camera app not launching . when i put reverse and the video wire of the camera is connected to aux video in I can get image from camera, but i need to launch the aux video app every time i put reverse.​

    I have something like this:​


    View attachment 5439271

    So my question are:​

    1) Is this a v1pro radio?​

    2) Someone has the same problem with the camera or knows what is happening?​

    3) There is any update for this radio?​

    Sorry my bad English, here are some pics from the device:​

    Thanks for your help​

    As soon as there are +12 V on the reverse wire your should see the rear view camera app with a black screen (if rear view camera signal is not connected).

    I think you have this device:

    Not a V1 pro with an old android version.

    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.

    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.
