check the connection of the camera, it must point to "rear cam" or "reverse cam" not connected to "video in" .. check the power supply of the camera. try to connect another video signal (old DVD player, etc.) or borrow a cvbs camera if the image appears , then you will know that you need to switch the input to AHD. Does your device support AHD? as far as I know, there must be an AHD chip present on the device board. take a good look at "developer setting" or "factory setting", try to click on the display where the camera is with an exclamation mark to see if the settings menu appears. I have the option to switch to AHD but I don't have a chip, so hardware is needed not only software. I don't have Junsun and I don't know exactly menu items. Maybe try to contact the seller or Junsun, where there is an option to switch the camera input.
[Android Head-Units] rigattoni:
Why not asking the seller for this pin there?

You even did not tell details of your head unit, like MCU version, Android version, stuff like that.
[Android Head-Units] fgarlam:
This is the information I have about the radio version. On the other hand, I asked the seller for the codes and just tell me the code of 000000. I think that’s insufficient

[Android Head-Units] rigattoni:
Well... Did you ever tray to search within this forum for "CVD1810 and PIN"? You will find a lot of other threads about your radio, even if it is a different seller. May be you find some more information.

Nevertheless: You really need to ask the radio seller for the PIN to change the setting. As also @dodo6 mentioned... check another cam.
[Android Head-Units] v1le:
Kinda same problem, although i just want to disable reverse camera because i dont have one. No menu, no option, no nothing.

I have the newest JUNSUN UI3.0 or whatever its called
[Android Head-Units] fgarlam:
I need the code for menu developer for this radio.
[Android Head-Units] rigattoni:
You won´t need the developer settings menu for that.

What you need is the PIN for the hidden system menu... and this only can be provided by the seller of the radio, if you don´t find it somewhere in one of the threads for this kind of units.

As I already wrote:
[Android Head-Units] rigattoni:
Yes, that´s what I wrote. Dev-Menu does nothing regarding those settings.

There is possibly be a separate PIN to enter a hidden system menu. There should be some setting regarding backup camera... should, no guarantee. I don´t know anything about your unit. So you really should have a look at other MCU related threads in here. That I posted now twice. ;)

If you don´t find anything and the seller is not responding accordingly, you need to buy another camera, which has the right resolution for your unit. There is no other way around that.

Edit: And just to be clear... You can´t change the resolution of the camera, you may be able to change the system behavior regarding the different resolution.
[Android Head-Units] dodo6:
Settings > at the very bottom "About device" > click on the gear > enter the code > confirm...got it right?

try code 1912 or 8878

-------

or try:

When reverse is on, tap the screen, a gear will appear in the corner.

And after pressing it, it asks for a password.

1111 - position, angle, line size settings.

0000 - adjusting the image from the camera (brightness, contrast, etc...)

maybe it won't help...
[Android Head-Units] fgarlam:
Thank you very much for your answer, I tried but I didn’t get anything. It’s a pity but I can’t find any solution online. It’s hopeless but I think it’s possible that this radio version doesn’t have factory settings for the rear camera thing.

You could install MainUiUpdater from here

Hey Folks - I just installed mine and I have a similar issue. My camera is working however the screen is black and white. And its seems that each part of the camera is in one area of the display.
[Android Head-Units] .:rogy:.:
Hi. It's very weird you cannot access setting with code 8888 or 8878. I think I have newest UI and it works. Please, double check if you enter via correct menu. On my unit I can change CAM type via the below steps (sorry for image collage).

I have however problem with detecting AHD cam. It only works if selected CVBS (and image quality isn't good). Camera is AHD 1080p, but it doesn't work if I select AHD-1080p-25Hz. Why ... I don't (yet) know.
[Android Head-Units] dodo6:

[Android Head-Units] flaviopac:
Same problem here. I have the same headunit with a rear view camera that has both cvbs and AHD modes.

I was only able to get the CVBS mode to work. Any configuration that I tried for AHD resulted in a black/white fuzzing screen.

My headunit should have the AHD chip (that's what I'm being told by the seller at least).

Any hints?
[Android Head-Units] zaballe:
I guys,

I found the solution. I'd some troubles too, and my researches arrived on my favourite forum (thanks XDA)

We must select :

- cam type : CVBS

- cam format : NTSC

AND to modify "reverse mode" to choice 2 "CAM" (for me it was by default CAM+OPS choice 0)

Then Save, reboot and then for me it works.

I got a problem with my oem rearcam

I cant get a signal on my hu.

Przede wszystkim trzeba wiedzieć jaka jest rozdzielczość samej kamery. Jeśli znasz to ustaw taką w radiu np. 1080 i to ustawienie trzeba zapisać (powinna być opcja zapisz lub sawe) i tak postępuj z każdą rozdzielczością. Musi zadziałać wczoraj to przerabiałem.
[Android Head-Units] dodo6:
what does the seller say? if you engage reverse, does the radio switch the input? try to connect +12v from the reversing light to the red cable
[Android Head-Units] Jeffiant:
I installed it with instructions from the seller the hu does switch to rear view i Just get no signal. The red cable is connected to the reverse cable (pin 14) from the schematic the seller provided
[Android Head-Units] dodo6:
I think that 12v from the tail light is connected to the reverse cable so that the radio switches the image. our car gives the radio information that it should switch the image via CAN. try to connect the 12v from the backup light to the red cable, in the case of an OEM camera, the converter will be powered by the 12v signal from the starter
[Android Head-Units] Jeffiant:
I have the oem camera wich one is the 12v signal from the starter? And wich cable should i connect to it?
[Android Head-Units] dodo6:
apply 12v to the red cable (reverse). Turn on the key, put it in reverse and see if you have a signal. If it will work, 12v only from the reverse light
[Android Head-Units] Jeffiant:
Okay i will try it later this week and keep you posted.

Hi

I recently purchased a Junsun V1 Pro.C 2G/32G unit for my Golf 6 2011. After connecting all wires and adapters everything is working fine except the OEM rear camera. When I put the reverse gear the radio changes to the park view but no stream from camera. I connected the "back" and "B+" wires (red and yellow) from the adapter to the "reverse" (pink) wire from the radio harness and "GND" to "GND", I also checked that it's really getting 12V (so normally it's not a connection problem).

I tried going through the settings on the radio to see if I can change anything regarding the rear camera stream with no luck

Would really appreciate any help.

Thanks.
[Android Head-Units] TorstenH:
Seems like the camera is not getting powered or provides no video signal.
[Android Head-Units] dodo6:
do you have an OEM camera? do you have an adapter for it? I think that the OEM camera adapter converts the signal to your Chinese radio. see the post above where oem does not work even with adapters

You should may try to put a noise filter for rear camera it is available on ebay or amazon or aliexpress
[Android Head-Units] housm:
I tested with a multimeter it's getting 12V. I'm convinced that I need to change the video format on the radio. I just can't find where to change it from

Hi Housim. I had the exact same problem with my camera. I had the put the ground wire to the car body and not the negative side of the reverse light. Also the reverse line from the harness to the red line on the camera wire . If you have a canbus like me then it should be the oink wire you splice into. Then I had a signal.

[Android Head-Units] Fumling:
My wiring looks like this, what should I do different? Ground is in ground, back is in reverse (pin 14) and my ACC+ is in B+ pin.

I also got this guide from their support with no luck.
[Android Head-Units] 2015_RVR/ASX:
Ok. Check you reverse line with a multi meter or light tester to verify 12V output. Put your car in reverse and check for 12V. When you put it back in park the voltage is "0". If you have 12 V then you are feeding it to your camera so that's step 1.

Then, on the camera end of the harness in the back of your car. Splice the red wire of the harness (the other end of the one you just spliced behind the HU/ the one along side the RCA) and the red wire of the camera power (the one with the black end). Then, the negative side of that same harness should be connected to you car body to get ground. Do not use the negative side of you reverse light socket (I tried it that way with mine and I got nothing on screen)

When I tried to connect my camera using the positive and negative of my reverse light I got no signal at all.
[Android Head-Units] Fumling:
Are you using the stock camera with RGB to AV connector? Because what you have sent it another guide.
[Android Head-Units] dodo6:
no, you don't understand OEM cameras, you need a video signal converter for your Chinese radio. I'm convinced that you won't solve the problem by changing the format in the radio, but maybe I'm wrong.
[Android Head-Units] Fumling:
Yeah, im using this one with no luck.
[Android Head-Units] dodo6:
what does the seller say? bring it back!
[Android Head-Units] Fumling:
The Junsun support is a joke, they seem to not understand English at all or just using weird scripts to help. They also don't even know how their own products work haha.

I've tried to get help via email and directly through Aliexpress with detailed explanation of the problem but they give me like guides on how to connect their own camera and stuff or give me wrong codes for older Android head units.

I think my unit is a new one where they have accidently removed the support to use the OEM rear camera.
[Android Head-Units] Jeffiant:
I agree i have the same expierence with the. Im still trying to get it to work :'(

I saw that you had some trouble getting into the camera configuration menu.

In my hu When in reverse and your tap and hold your finger on the Screen and then a cogwheel will aprear and the pin is 0000 atleast on mine hu

Junsun V1 Plus + VW Passat B7 OEM rear view camera not working

Hi group, I have an annoying problem, I can't get the OEM rear view camera to work, tried the instructions I got from the seller and also different connections that I read and saw on YouTube but I can't get the camera to work. I have a VW Passat...

[Android Head-Units] 2015_RVR/ASX:
So after a lot of searching I got my camera to work. Because my car had a factory amp and sub I knew I needed a canbus module. When you vehicle has this then your reverse trigger wire with not be labeled as "Back" or "Reverse". It will be the third wire from the side of you android HU harness plug. Its next to the red wire and is usually pink, but in some models like mine it was brown. I spliced the red wire next to the RCA end into this and it supplied 12V to my camera when it shifter goes in reverse. This is the only power the camera needs. The negative (-) black wire to the camera is grounded to a body screw in the back.

Option 2. (No canbus). The trigger wire labeled at "Back" or Reverse" on the harness. Connect you red wire next to the RCA cable to this wire. In the back, Connect the other end of this wire to the positive side of your reverse light socket. Again, Attach the negative (-)black wire to a body screw.

OPTION 3 If you have a VW and some American cars, you will need to install an inline filter (available cheap on amazon) as some of these cars have fluctuating and unstable 12V power. Filter installation.......

Input Red Wire: Reversing Light Positive Pole

Input Black Wire: Reversing Light Negative Pole

Output Red Wire: Camera Positive Pole

Output Black Wire: Camera Negative Pole

Hope this info helps everyone with camera problems

So the manufacturer apears to be alps and it seems to be based on the AC8257 hardware which also gives a lot more hits if i google it.

IMPORTANT: If you reboot into LineageOS before installing Google apps, you must factory reset and then install them, otherwise expect crashes.
This also applies when you experience issues and want to try an older or other package of these apps.
