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

[cblossants]

The camera socket is yellow with a pink wire but since I couldn't find where to connect the red wire that comes from the reversing lights, I had to connect the camera to the yellow cable between the videos of the car radio because if I plug it into the camera socket it can't work and the red wire with the pink one doesn't change anything! Thanks

Ah OK, then your unit is different than mine. In mine when I put the car in reverse, then 12 volts are passed to the pink wire which powers the camera. Is your canbus working, e.g. when you open a door then it is dislayed on your screen. If you connect the red wire to the pink wire, does your screen change from Android to black, but with no signal?

No, if I connect the red wire from the camera to the pink wire, nothing happens! I have no open door signal with my canbus my car is renault clio 4!

Then I guess that you need to connect the black connector on the main head unit harness and connect the camera to your reversing lights. You could try connecting the red wire to the brown wire as suggetsed by your seller to see if that works

Yes I will try tomorrow thank you

Hello and happy new year to everyone ! I have a question, I've never managed to get the camera to work by going into reverse! The seller told me to connect the red wire coming from the back to the brown wire that goes to the radio except that the brown wire number 14 on the diagram is connected to the can bus, he told me to cut it and try! I'm afraid of damaging the radio. What do you think ? Thanks

The brown wire on pin #14 is an input for 12V+, it's the trigger for the head unit to switch to reverse camera mode.
The red wire from the back should be connected to the reverse light. So it will provide 12V+ as soon as you switch to reverse gear. This wire is connected to your can box and the can box should forward the information "reverse" to your head unit. This seems not to work and so it is a good alternative to connect the red wire with the brown wire directly.

This time big exception (we should mark it in our calendar): The Chinese head unit seller has a good idea and you should do what he says. :-D

Le fil marron sur la broche n ° 14 est une entrée pour 12V +, c'est le déclencheur pour que l'unité principale passe en mode caméra de recul.
Le fil rouge de l'arrière doit être connecté au feu de recul. Il fournira donc 12V+ dès que vous passerez en marche arrière. Ce fil est connecté à votre boîte de conserve et la boîte de conserve doit transmettre les informations "inverse" à votre unité principale. Cela semble ne pas fonctionner et c'est donc une bonne alternative de connecter directement le fil rouge avec le fil marron.

Cette fois, grande exception (nous devrions le marquer dans notre calendrier) : le vendeur de l'unité centrale chinoise a une bonne idée et vous devriez faire ce qu'il dit. :-RÉ

A super Thank you very much for your affirmation of what the seller told me because as the brown wire is connected to the canbus and to the car radio I was afraid to cut it to connect the red wire! I'll try I'll be fine!

Don't see any problems here. You can't destroy the unit by doing this. But cut it in a way you could connect it again without opening the can box: Not directly on the case of the can box (better save that than sorry).

hi all. There is a firmware with a screen resolution of 1280x720. CarPlay looks just awful, huge icons. I tried to change the screen resolution to 1024x600 the image does not fit on the whole screen. how can i win this?
I'm writing through google translate, sorry in advance.

 

[Gaga92i]

Ne voyez aucun problème ici. Vous ne pouvez pas détruire l'unité en faisant cela. Mais coupez-le de manière à pouvoir le reconnecter sans ouvrir la boîte de conserve : pas directement sur le boîtier de la boîte de conserve (mieux vaut garder cela que désolé).

OK thank you

I have just installed Agama Launcher, disappointed that neither Google Maps nor Sygic show direction information in the centre of the launcher, guess there is no solution? A!so I cannot map my 'Car Info' app to a button as it does not appear when I go to select apps. Any ideas how I can map it?
Thanks

Car info is just an activity of mainUi.
Here you can find a lot of shortcut apps which link to activities of MainUI:

Junsun V1 - start equalizer/AUX/BT music/CarInfo... from launcher

The app equalizer.apk starts the equalizer (activity com.ts.main.Media.ADASMainActivity): EqualizerShell.apk starts the equalizer (activity com.ts.MainUI/com.ts.set.dsp.SetDspMainActivity) via su shell command. See post below for further...

And here you should find an app linking to Car info (I think it was in the car_apk.zip):
Post in thread 'Junsun V1 - start equalizer/AUX/BT music/... from launcher' https://forum.xda-developers.com/t/...-bt-music-from-launcher.4237797/post-85047137

Someone told me that it opens an old version of Car info. Unfortunately he didn't helped me to create a version linking to the new activity. So let me know if it opens the expected screen.

Hello I wanted to use Android auto but whether it's Spotify or amazon music or radio tuning it works for 3 seconds then goes to stop so I press play and it starts again do you have any idea? I uninstalled Android auto several times and it's the same I have the latest firmware! Thanks
I have the Junsun 4G Pro

Hi, it opens the same version as what I have, at least I don't see any difference. Many thanks

Only for your information.

I bought a Junsun 6GB 128GB.

It looks like the installation of the internal mic was changed. The mic is not longer soldered with cables, but directly on the circuit board.

I have made several calls with it and it works fine.

I have to say, that I make calls with a sim and not via bluetooth.

A photo would be nice.

The question is still if they changed it for all variants. In meantime learned a Junsun V1 (Pro) is not as Junsun V1 (Pro). They sell it with different CPUs, firmwares and UIs.

It is possible that this is solved differently in others.

Here the pictures.

When I drive reverse, the reversing camera turns on. If I then switch back to forward gear, the camera image is displayed for another 5-7 seconds.

Is there an option somewhere to set the delay for the camera if you drive forward again?

How is the reverse wire connected? To the reverse light?

No it goes directly into the head unit with the 6 pin plug. The rest I think makes the Canbus.

I think only the camera picture is connected with the yellow cinch connector of the 6 pins cable.

The trigger wire should be a brown wire which is not connected by default. Or are you using a can box?
