Junsun V1 Pro MTK8259 4GB + 64GB Android 10 headunit

You unsoldered and then soldered cables in the same order as they were before? And what app did the seller activate?

Desoldering, I cut the wires and then I re-soldered in the same order of colors as it was. All manufacturers (in theory) have to follow the same standard color code. The code they sent me to compensate was the standard edition of Nexvoice or Toppai (Junsun's voice assistant)

Before desoldering it was not working and after cutting the wires and solder in the same order as before, it worked?can you check please according to the plug what is the right order in sim socket?(between Red and blue wire is Green but don't seem in photo left and there is one Black cable that in connected in the other side of the plug in photo right)

 

[AlbertoBmwe90]

What is your SIM adapter, photo left or right? . The correct order according to my Sim socket would be according to the image I attach. The radio connector, I have not been able to verify its order

Edit: The photo on the right, I didn't pay attention when I repaired the cable. If it works like that, I wouldn't play anymore.

If it already works well, and you are well welded, do nothing else. There are times when trying to improve, it spoils something else. Greetings

Hey all, I need help with my junsun v1 pro 4gb +64gb-mtk8259- I just had it installed and everything works except Bluetooth. I can make calls from unit and or my cell phone. Apparently the people I call can hear me but I can't hear them. On occasion as it dialing I hear the ringing for a second then it cuts out. Is this a hardware issue, install issue, or something I need to change in secret menu?? I've reached out to junsun with no luck. I fixed the issue with the swc thanks to this forum!! Hoping someone can help me. Car is chrysler 300c and phone is samsung galaxy note 20.

BT audio is working fine but has a small bug.
For starters, check the Infotainment Options -> Sounds and adjust the level of bluetooth audio.
Also, when you start a call, the BT audio level between your phone and the HU will try to sync.
Therefore try to use the volume buttons on your phone (while the call is in progress) to raise the volume and see if that helps.
If it does, then it's your phone that once it connects tells the audio to go in very low level output.

Thank you for reply. I tried to adjust volume in secret menu and my phone, still no sound. I tried a different phone and same thing happened. Seems to me the unit is not allowing sound to come through speakers. On occasion you hear it for a moment when can first starts then cuts out. Wonder if I should hard reset the unit to see if that helps. I love the unit would rather not return it but I absolutely need Bluetooth calls for work. All the other items work fine with bt.

Does AD2P work ok ? (Streaming audio from your phone to HU via Bluetooth)

Yes music plays fine.

Then it must be a setting or something similar and not a faulty unit. I can't help any further though as it works fine with my Samsung S9 from the first moment the phone got connected.

There is a claim on the website that a new headunit with 6gb +128 gb setup uses QLED display. Anyone using this variant? Seems fake a little bit but all of the other info checks out. Cant find anything about the SoC tho.

I have seen OLED displays on Android headunits as far as the beginning of 2021. I would not pay for it as OLED displays tend to break easily in extreme conditions (the car can get very cold or very hot easily).

I agree. OLEDs burn out and wear much faster when there is a hud style image shown constantly on the screen. However QLED is just regular LCD with added quantum dot layer for better colour, sometimes they add a better backlight layer too. I just searched for any other headunit with qled display and there are some so i think a manufacturer produces qled displays in these sizes so they just slap these in for the top units. Not sure how much better it gets with this upgrade.

My bad, QLED is not OLED. Maybe one needs to see the screen in real life in a car before jumping to a QLED head unit.

Issue with Bluetooth resolved. Speaker inputs had to be reversed. Now Bluetooth working perfectly! My installer said cars with more than 6 speakers have this problem with these units. Loving the Android unit now, looks stock in my car with all the features of a tablet. Thanks all for your help

How did you reverse the inputs? I got this unit since today and have the same problem. It also sound much worse then my stock radio.

Has anyone had a go at fitting a 360 aftermarket camera like you can find here?

My unit certainly has the input on the back for it, but I can't find any reference to the 360 app to actually view the camera. Has anyone else got a 360 camera working?

Tempted to buy for an experiment.
