Reverse Camera APP?

If your camera isn't wired to your reverse lights (i.e.: only powered when in reverse) you can split the cameras RCA cable with a Y adapter and run one to the backup camera input and one to the AV input, then use AVIN to view the camera at any time. Note AVIN will take over the sound as well as the picture, but this is the easiest way to do that AFAIK.

OK thanks, ya its just wired to the cigarette lighter wire for power. ok thanks seems like to much work, I thought it would be something simple like an app, dont feel like running a whole new cable from front to back.

You don't have to run a new cable like that, or even disconnect everything. Just pull the unit out enough to disconnect the camera, put on a Y splitter and connect it to reverse camera and AV in :good:
If your head unit comes out easy should be ~10 minutes.

I have a problem with my camera - when the HU is fully booted up, it does not switch to reverse view. When it is booting (i.e. while in boot animation), it shows up correctly. I checked the signal, it's 12v when engaged reverse. I've tried reflashing stock rom with Malaysk, reflashing mcu; nothing works. Enabling the front camera in factory settings, putting in reverse and manually starting AVIN with reverse camera, it works. Any idea why it stopped automatic shift into "backup camera mode" and how to repair it?

Did you update your MCU file.. Look under factory settings and enable rear camera if it is not (might be called something else)

actually, i downgraded it.. from 2.86 to 2.85 as i havent found newer one for KLD6. I checked the factory settings toroughly, nothing helped. The problem came out of the blue, one day all was working fine, the next day this problem. No change in settings, installed apps, nothing.

Found it - using another "radio" setting under factory settings turned the cam back into normal operation!

Now my FM radio doesnt work :D with neither radio i choose. Some produce weird noise when chosen, some completely silent.

Is there any list of devices which radio should be set to which device? Mine is Eonon GA2114.

Regards,
Tine

I simply wired in a 12v switch to manually enable the rear camera. You will need a resistor but it's simple. When the head unit notices the camera getting power ( via switch ) it switches to the backup camera automatically. It does require running a power lead from somewhere though. I pulled mine from the power accessory wire, ran it to the switch, from switch to resistor....then to the radio.

O.K. we used to be able to launch the reverse camera by using F-Cam.apk and selecting the camera icon on the left side of the screen.
As long as the camera was powered and video while driving was enabled in the "driving" settings it would give a full screen view of the backup cam at any time regardless of what gear you were in. In malaysk 4.4.4 I have not found the icon on the left side anymore.
I tested his Lollipop build, and the icon is back in F-Cam.apk. and once again I can view the backup cam while driving around.
The backup camera may well be controlled by the MCU, but it is accessible through the F-cam App depending on the version.
Not sure why it doesn't work in the 4.4.4 anymore, but I hope to find a solution.

Any progress on this issue? I own a Android PX5 for my Prius. I am able to see my reverse image when I shift in reverse, but can't see it while driving. F-cam does not seem to work. Any other solutions?

My camera is always powered when ignition is on.

edit: Can you post the F-cam APK? I used this app from the Play Store: https://play.google.com/store/apps/details?id=com.apexis.p2pfcam&hl=en

I assume they are not the same?

The F-cam Apk you link to is not the OEM F-cam apk I was speaking of. The one I am looking for is pre-installed
on my MTCB head unit.

That being said, I decided to go with a hard wired solution. I bought an RCA cable splitter, and plugged my camera into both the camera port, and the AV IN port. By doing this I am able to see the camera when I an in reverse, or when I open the AV IN app.
My camera is constantly powered when the vehicle is on.

Got it working, when I switch 'front camera' to enable in the factory settings, the F-cam app showed up in my app drawer. Inside F-cam I can enable my rear camera while driving. Nice gadget :)

Does anyone know how to change which camera gets launched when there the reverse trigger line has voltage? I know this is in the MCU and not android.
Here is my scenario -
Installed in an RV.
Camera has microphone since normally a spotter is used when backing into tight spaces.
So when the reverse line has voltage, I want the AVIN leads to come up not the Back-CAM


I know I can kick in the AVIN manually, but I don't want a two step process especially for turning. My RV has a video switcher that runs a lead out that acts like the reverse camera, but it will change from reverse to side camera based on if the shifter is in reverse or if a turn single is on. That is the lead I currently have in the AVIN to get the sound also.

After installing my front camera by RCA input, I only can see the image with AVin.apk and not with F-cam.apk (I would like to see it with both).

Anyway, my main problem is that I bought a rear camera to be used as a front camera, so it has screen mirroring enabled by default. Does anyone have a modified AVin.apk with screen mirroring image option or something like that? or does someone knows whether there is any way to do it changing any option?

I would like to keep the camera without buying a new one. PLEASE, PLEASE, PLEASE

do not you have 3 extra wires on you camera harness to switch mirror effect in your camera ?
like here "NATIKA Backup/Front View Camera"
"https://www.amazon.com/NATIKA-Backup-Camera-Waterproof-Reverse/dp/B07H852D49/ref=sr_1_13?keywords=Tailgate+Backup+Camera&qid=1555372080&s=gateway&sr=8-13#customerReviews"
it's a very nice camera so far.
maybe someone know better ones ?
