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

Thanks!,
So it's the red, and yellow that go to the positive and the black to the negative. That red comes to the input connector to the radio from the cambus while the other two come directly from the quadlock.
So I have to connect the positive of the transformer to that red just before the input connector, right?

Connect pin 8 and pin 15 to the positive (+) output and pin 16 to the negative (-) output of your power supply (transformator).

CAN box connection is not needed to start the head unit.




I don't like to talk about wire colors because they may be not identical for different harnesses.

You could try to change video format in factory settings (code 8878, section Others). There should be the possibly to switch from/to PAL, NTSC and maybe more.

Thanks it worked!

Thanks it worked!

Happy to hear that. And thank you very much for reporting success.

Hi,
I have Junsun V1Pro 4/64, I installed AGAMA launcher, set as default launcher. When turning on the HU, the screen remains dark, no launcher works. I have to press the Home button to start the launcher. After that, AGAMA works without any problems until the next HU start. Well thank you.

I have the same shell, and starts without problems. I have the HU V1Pro 8core 4RAM/64ROM

I use this to stop the system from closing Agama when I turn my car off. It works great.

Does anyone has experience how to change car source button apps/inputs?
Right now i have radio, bt and music. None of them i don't use often. Rather i would like switch to homescreen.

Hey all, I don't know a better place to ask this question, so I'll ask here:
Does the V1 Pro actually support WIRED carplay? If so, how does it work? I've read at some posts that suggest using the 4-pin USB cable, but I don't know how to actually get it working. Wireless Carplay works fine, but every so often it loses signal and cuts out for a few seconds. Also, my phone gets quite hot with extended use, so I hope wired carplay can solve some of these issues.

Hi, thanks for the advice, I installed the app, whitelisted Agama and Agama is working. Once again, thank you very much.

@TorstenH Thank you for the support you providing here!

Do you or anyone else know how to make static reverse camera lines dynamic?
When i installed the camera (original junsun dynamic camera) it showed dynamic line when i moved the camera itself but really not much. When i move my steering wheel it just doesnt move the lines at all.

i tried everything i could find in the normal settings and in the 8878 menu

Usually dynamic reverse camera lines depend on CAN bus information regarding the steering wheel angle. This allows head units to paint the lines on top of a camera picture.

So the question is: How are dynamic lines generated by this cam? At least it's my expectation that the camera itself is "painting" the lines because there seems no additional data connection required. Sure it's not GPS and it's not gradient.

Maybe it's getting calculated by the picture itself but that requires that your car is moving backwards to be able to calculate an angle based on changing pictures.

Does the line change while you're driving backwards?

I found some hints from another camera:
It seems to be important how the camera gets mounted:


The lines getting calculated by the cam based on the moving. This means it will not response with adjusted lines if you only change the angle of the steering wheel. As I mentioned that's only possible if your head unit is connected with the cars CAN bus.
So there is nothing you can change on the head unit itself because in this scenario the head unit is just a stupid monitor knowing nothing about the lines. According to the product description of this camera you must turn off the lines on your head unit if you see too much lines - what makes absolutely sense to hide the static lines painted by the head unit.

I can tell how exactly they are generated but the camera is advertised with it.

i cant test the camera with backwards driving right now its pretty late here

Other head unit - same topic:

Do dynamic guidelines for backup camera only work for installs with canbus? (TS10/Topway/Oknavi)

Hi On my unit backup lines are fixed, they are not curving as the car is backing up even though the feature is on. Is this normal for cars that use no canbus? I have TS10/Toway HU.

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.

 

[musicdjs]

Thanks it worked!

Can you write what exactly you changed in the options or send photos from the menu, it will definitely help for more people, thank you and best regards

With latest v81 my unit also goes to shut down faster. Yesterday after i was putting gas in my car for few minutes. Setting for sleep vs shut down lenght would be really helpful.

 

[Ivo_Svk]

Today i tried versions v81, v61 and v50 which I know worked on my other unit but unfortunately,not on this one. I think it must be something in the settings, or maybe canbus
