Okay so Im trying to get my Eonon Andoid head unit for my E46 BMW to switch to Reverse Camera when I put it in reverse. I have wired the camera up for power from my reverse lights and ran RCA to the front and connected it to the head unit. This worked fine when my car had an Auto transmission but after I swapped my car to a manual transmission the camera will not auto launch on reverse. It does work as I downloaded an app to open camera and when I put it in reverse the camera shows whats behind me. But if I'm not manually opening the camera app the head unit does not switch. Any ideas?
Eonon may have mislabel the RCA lead, did you try the other video in leads? It should have come on when the camera got power from the reverse positive lead. May also be a firmware issue. Contact Eonon on Facebook and describe it to them. They may send you a firmware update.
I'm wiring up the harness for my car, but I've got no clue what the "Brake ctrl" wire is on the Panlelo head unit. Cannot find anything on Google either.
Does anyone know what this is? I know it's not the wire to switch on the rear-view camera.
Thanks in advance,
Tony.
It likely connects to the switch on the emergency/parking brake, the idea is to disable video unless the car is stopped with the parking brake applied. IME most of these headunits have a setting that can disable this feature meaning you likely don't need to work about it, alternatively you can just connect it to ground that will make the headunit think the parking brake is on all the time.
Hi, just installed my new Android HU in my Golf MK5, I have configured everything and it is working great apart from one issue no matter of searching has got me to the solution.
I do not have a reverse camera installed but every time I put the car in reverse it goes to a black screen as it is was there.
As far as I can tell there are 2 usually solutions to this:
1) Turn the option off under ‘Extra Settings’. My particular unit does not have an Extra Settings menu and I have looked at all other settings and there is no option as far as I can see to disable it.
2) Cut the reverse signal wire going into the head unit. My HU takes the original wiring loom from the car with no extra CANBUS. I have checked wiring diagrams there does not appear to be any dedicated wire for the reverse signal.
Can anyone help me get to the bottom of this please? Let me know if you need any more information.
Option 3: Install Backup Camera
FYI You didn't list the HU model so not sure anyone can help you. On my IDoing uis7862 it's in the settings to disable auto switching.
I'm also looking to disable that option in my head unit. Its a 8227l installed on a Peugeot 407.
For now I will keep the camera for another time when I have the budget for it.
You have to identity the REVERSE wire of the wiring harness. You car provides a +12V signal on it as soon as you enter the reverse gear. You can unpin this wire - don't forget to isolate it.
Another approach could be to disable the Android activity which presents the picture of the reverse camera. This can be done via ADB command (Google for it).
It requires to get the package and activity name but I think there are apps in Google PlayStore available which can list the recently started activities.

Thanks! I will look for that. I'm pondering installing a camera, so this solution would be temporary.

Then, if I were you, I would not invest time in this issue, because it is not a malfunction for you.
I've searched for my particular scenario and I haven't exactly found it. I have a 10.1" android headunit sold by Rongji listed here:

I've wired my reverse camera into the back of the headunit for power and the AV cable is plugged in accordingly. When my vehicle is running and I go into Reverse, nothing happens.
However I can click on the F-Cam app and choose reverse camera and the image shows while in Reverse.
Is there any way to make this happen automatically?
I've not understand the comments I've read through where some say the reversing action is managed by the headunit software not by F-Cam. If anyone can explain that would be greatly appreciated.
Thanks for help, links, info.
F-cam has nothing to do with the back-up cam. It's just a separate app which allows manual control of the cam. You don't need F-cam at all for the reversing cam feature to work.
If you don't have a can bus box then you need to connect the reverse trigger wire to the reverse lights (the orange wire from the head unit).

If car has canbus, it can be solved by adding relay. Activated by reverse light power, relay is suposed to switch some stable voltage to suply camera. For example cigarette lighter voltage can power camera. Here:

Toyota C-HR hybrid is my car, if that's interesting.
no in my opinion the 32pin iso cable where the original rear camera cable passes is not well wired because I saw that there is no power to the rear camera. we have to find the problem and solve it. if you succeed let me know how you solved.

I haven't had any results yet. Maybe you should try pairing the canbus first. It installs an extra app with car setup options.
But I have tried in vain so far, there are too many choices. Although I found my car on one of the models, I didn't get the picture of the reversing camera.
The seller's response today is:
"Did you connect the Cam in port on our power cable to the Rear camera input port on RCA cable."
Of course there is no RCA, there is a canbus.

I did it, but nothing happened ...
There are two CAM IN RCA connectors on the POWER harness. I tried both, although nothing from the factory radio is connected to one of its pin connectors.
Hi, is your hu with 360? If so, then k7 will use the 360 cam instead of your existing cam. The reverse cam will only work if 360 app is not running. Try restarting the hu while in reverse. Then as the hu boots the reverse cam will show at for a few seconds.
If hu did not come with 360, then check the reverse cam type.
The rca connector is in B harness not power. It is brown color. Then if you have canbus, it should be automatic. Make sure your reverse cam is terminated properly ie. Power and ground.
i have TEST YOUR SOLUTION, i don't have 360 camera , i have CANBUS WITH BROWN CABLE but i when insert rerar gear not appear. if i open app for vision cam the message is NOT SIGNAL.
i have test at connecting at aftermarket cam and i see image in app. where is the problem of my original cam??

No, there is no 360. But only part of the problem is that there is no reversing camera image!
Unfortunately, nothing works about CANBUS, only the left side of the steering control.
The seller also sent a picture of the camera connection. I repackaged the radio, checked it, everything is as pictured! It also sent about CANBUS type selection, but it is.
No door opening, no radar, no air conditioning, nothing ... Who doesn't have a reversing camera, do the other things work?
I have write to winlink ownice and the result is the camera original not work and seller send me a camera sony! When arrive i test
The problem for me is in the canbus decoder not support rear camera original. Because the original camera is 6v but radio send 12v

Considered installing a voltage regulator and using the factory camera, like for Toyota models?
The knockoff won't be a Sony...

For me, Toyota C-HR hybrid is my car. Unfortunately, nothing works about the CAN BUS, not just the factory reversing camera. But I think the Toyota camera is 12V. Now I’m there for the seller to contact the engineer to see if the smooth and hybrid CHR require the same CAN BUS. (There is a different type of hybrid in the Factory menu.)

Has the promised camera arrived? Now they promised me one too. I hope this already works, although I would have preferred the original to work!
Funny mixture of topics here.
You need +12 V on the reverse cable of your head unit as soon as you in reverse gear. This is just to tell the hu that you're in reverse. You can grab the reverse signal from can bus box or from the wiring harness of your car. Use a multimeter to verify if you get the 12 V. Search for the pin description of the original OEM radio.
