I have this exact same problem!

What phone are you using?

If I connect Samsung S21 to headunit it works normally.

If I connect Motorola G82 the Bluetooth connects but the sound stays on the phone.

I've tried resetting everything on the phone and the headunit but still it's not working.

Has anyone else had this problem or found a solution?

I am currently using it with Oppo Reno5 Z.
Maybe he doesn't like the phone? :)
The only thing that is interesting is that the sound was output to the car's speakers until the first software update.

I don't know if it is your case, but I had a similar problem when I installed my reverse camera. The problem was that when starting the engine the video signal was very noisy, the cable coming from the camera is triple, ground, video and positive (red) (the one that informs the HU that the camera is on, that the reverse gear is activated and thus automatically shows the image).
My solution was to run a second independent cable, and on the other side to use it as a positive.
Before disassembling the whole car, do a test by connecting a cable in the middle of the car, if it works, you know where to go.

My opinion is the same, the problem is the noise. I had this problem in power line, and it solves puts a diode in serial to insulate the camera and a capacitor like voltage stabilizer.

Hi
I bought a junsun v1 pro for my rav 4 2017. But I can't seem to get the original rear camera, nor the 360.

I saw some people were able to get the camera to work by setting to Ntsc or PAL format but I don't have access in my version. With the code 8878 in the settings I only have access to CVBS, tvi, ahd...

I tried directly by going to the parameters in reverse with the codes 0000 and 1111 but I can't change the format

Can you help me?

Hi!
I would like to turn on the radio without putting it in the car yet and configure it like this. If I connect the red cable from the quadlock and the black one to a 12v and 2A transformer, will I be able to use it normally or do I also need to connect some other cable? Thank you

You just need to connect B+ and ACC to the positive output, GND to the negative output of your 12V power supply.

Junsun V1 pro won't save settings
So far i've tried:
Adding USB drive as Android space, also as travel media for music
Reset
Update to v61
Manual save to USB drive via 5555 code
Manual save to SD does not work
After restart head unit loses radio stations, equalizer settings

Car is Peugeot 207, Junsun V1 Pro with 64GB of storage and 4GB of RAM
Any tips are welcome

    @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.
    Click to expand...
    Click to collapse
    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:
    IMG-20210301-WA0001.jpg
    Sure, the other side of the connector need to fit to your car.

    Here for your reference:

    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.

    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.

    Firmware installed in meantime?
    Click to expand...
    Click to collapse
    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.
