Hi, I just updated firmware on my unit to v28. I had an app installed which rebooted my unit. I think that I downloaded the app from this forum, but i cannot find it. Can anyone help?
Thanks

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.

In the last few weeks my wireless CarPlay connection is lost, maybe every half hour. The seller recommended that I update to v28 which I did, but my wireless CarPlay is still disconnecting every now and again. Are there any settings I should look at, or possible solutions?
Thanks

Can you explain step by step what is the procedure for mcu update?
The file in post 1242 how can be used?

Click to collapse
You download the file, extract it from rar, copy the file to usb, instert the usb into your headunit (preferably the usb port with 6pins), then on your headunit go to settings -> car settings -> about device -> enter the hidden settings via code 8878 -> the third or second option will be mcu update -> press it and then press mcu update -> restart your headunit a you are all set.
Please be aware that if you don't know what you are doing you can brick your headunit so be careful.

    @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 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:

    Sure, the other side of the connector need to fit to your car.

    Here for your reference:

    Untested but may work:

    Put the logo on the root folder of an USB drive by naming it
    Code: 
    tslogo.bmp
tslogo.jpg
or
tslogo.png

    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.

    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.
