Thanks so much for the response! I have tried it inmediately.... unfortunately it doesn´t work... don´t know what more can i do... i tried hard reset, flash firmware and install apk.... radio still no working
any help please? thanks very much!

regards!
After installation you have to enter "Seting -Car Infotaitment - 888 ...... Factory Setup- Radio" and re-check the box with the type of radio CIP (IC Typ: 7708, Zone: Europe), then Save Seting- Reboot .
That's how I suffered after reinstalling the radio firmware, it didn't work anymore.
Please be patient and read back. As I said above, this solution was posted. Just have a little patience and read on.

După instalare, trebuie să introduceți „Setare -Informații auto - 888 ...... Configurare fabrică- Radio” și bifați din nou caseta cu tipul de radio CIP (IC Typ: 7708, Zona: Europa), apoi Salvați setarea - Reporniți.
Așa am suferit după reinstalarea firmware-ului radio, nu a mai funcționat.
Vă rugăm să aveți răbdare și citiți înapoi. După cum am spus mai sus, această soluție a fost postată. Doar aveți puțină răbdare și citiți mai departe.

Rodry26, procedeaza astfel : Setting-Car Infotainment-About Device-"Seting" on the top right of the screen-Type 8888-Radio
and there you do what I wrote above (you have to activate the IC type and the Europe area).
That's exactly what I suffered like you. After reinstalling the firmware, the Radio did not work at all (just like in your movie). Don't forget to Save and Reboot after making these settings. Succes

Hi guys!
This post is very useful for the owners of the Junsun V1pro, thank you all.
I've an issue with my unit on my accord 2009 euro, the radio lost the signal every 5 or 7 seconds and I've found that there is a blue cable on the antena cable provided with the unit that have to be connected somewhere... but I dont know where. I've search on google where it should be connected but I didnt found the correct pinout for my model because all I've found are from USA.
Another critical issue is the bluetooth calls, I've disable the internal micro, I've plugin the external micro on designed connector but the calls are really bad, the sound is scrapy at all, nobody can understand me on the calls... have anyone any solution?
So, please, if someone have the correct pinout for the antenna and a solution for the calls it will be very useful!

Is this blue wire COMING from car side and is it bundled with the antenna wire?

I have also a couple of questions:


1
I agree with #245 - the sound quality from the onboard mic is terrible. I connected an external mic too, and the quality has improved a bit, but still far from good. Is there a solution? Has anyone got an acceptable sound quality?

2
The HU is installed in a Renault Clio IV. I connedted everything as it should and I found the right CAN-protocol and rebooted the HU. Still I have no connection to the cars CAN BUS, therefore my SWC don't work. As I checked the pinout of the connector in the car, I could see that the wiring harness that came with the HU and should connect the car to the CAN BUS interface and the HU had a blank space without a pin where the low CAN is placed in the cars connector . Since the CAN signals is a difference between the high and the low CAN that means no CAN signal is transmitted with the wiring harness. Is it common you have to modify the harness you got with the Junsun HU?

Best regards form Denmark

In my settings to enter the radio chip, the password is 8878, not 8888.

Hi,
I would appreciate your help.
I just got my brand new device. 4/64 junsunv1 pro.
After setting everything up, I have an issue with the reverse cam. When moving the gear to reverse it's display "no signal".
Previously I had an old android device in my 2008 grand Vitara, and I decided to buy a new one. The aftermarket camera worked in the previous system and I just connected it as I suppose.
I was reading this thread all over and couldn't find anything that can help me.
I tried to change video setting from cvms to all the other setting and it doesn't help. The only thing that I noticed is when I set to 360-720 and moved the gear to reverse, the reverse showed in the right hand side of the 360 cameras very corrupt.

Hope you can help me.

Hello everybody,

I have a little and stupid problem. My head unit have no internet if the sim card is installed. I can make calls and receive messages. Mobile data is activated on the device and APN is working. Same SIM card in the phone has no problems.

Thank you for your help!:)

    I tried several things. Nothing helped...
    Here is some pic's I've taken... Maybe someone knows how to change ntsc to pal...
    In my case (different car) backup camera was feed from CCD AVIN and it looks like that input is shared with 360 surround system back camera.
    Changes in 8888 -> Backcar Setup affected 360 system and back camera connected in CCD AVIN.
    Gift camera I received with unit was working on CamType CVBS.
    360 Surround System is working on CamType 360-720P setting.
    When I had connected 360 system and back camera in CCD AVIN image was corrupted and flickering (sometimes you could see parts of one or the other image).

    I have a brown/black (brown goes in CanBus brown/black coming out) the instructions says that its the wire.
    I think its something that i need to change on my Screen. Any other Ideas?
    No, just connect to this wire...

    no, all the settings stay ok. and i dont think the clock resets it justs starts always at the same hour. 03:18.
    If it starts always at the same hour, then for me it means it resets itself.
    For me workaround was to set clock synchronisation with GPS and not cellular.

    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.

    Seller just told me that I have to send back the device, this can't be the only solution?
    I got my Internet working. The problem was that the headunit searched up an old APN for my simcard. So I made a new APN profile in the settings with the values found on my operator homepage. Worked fine after that.
    Hope it helps you to.

    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.

    Hi, I have this same radio. I tried to connect it to the computer as I read here and I could not do it. What I would like to do is to root it and if I can put the TWRP RECOVERY. I have not been able to extract the boot.img from the firmware.bin. On the other hand, the "back" button has been deconfigured and now the action it does when I press it, is that I turn off the screen. Do you know how to fix it? I have used the "BUTTONS REMAPPER" application but I have not achieved anything.

    Best Regards
    Did you try connect with Flash Tool after MTK driver installed? How did you understand that no connection? About buttons remap - consider should be enough to uninstall buttons remapper.
    What car do you have?

    Hola chicos, soy nuevo en el foro. Tengo la misma radio de hace unos meses, y no sé si les pasará lo mismo a los que tienen un Peugeot 307, y son 2 cosas. 1 kilometri pentru revizuire, lo reseteo, dar atunci când începe la ziua următoare, întorc 0 cu simbolul llavei. 2 ca schimbare la oră la ecranul central, ya que la hora se adelantó en mi país, se actualizează la radio dar în ecranul de serie al auto-ului nu se actualizează. (Lo siento por mi ingles)
