[Honor 6X Questions & Answers] venugopalu007:
Ho nice one that's pretty good explanation.
[Honor 6X Questions & Answers] alnaloty:
this is my solution ( made by me ) after trying many solutions over this forum @ other forums

just

1- delete any folder for themes u made (as hw_init or themes in root folder or at any site )

2- make folder & name it ( HWTHemes ) in internal memory

3- download this folder & put it inside (HWTHemes )

4- go to themes app and chose ** Aqua theme ** & apply it

5- no need to change any permissions

this was try on huawei y 7 2017

Mod device you need to understand all the risks.

Neither I or the website is responsible for your actions and possibly killed devices!

After take a loock of schematics I found how to add the front parking camera.

Here you can find schematics: schematic

The video input is in the video switch FMS6502 IN2 (pin3) :

Screenshot_2017-08-27-17-17-07 by Hugo, en Flickr

We have to connect the camera signal to pin 3 on FMS6502 in series with 0.1uf ceramic capacitor and 75 ohms resistor to ground. (see schematics for reference)

IMG_20170821_202803 by Hugo, en Flickr

Now we need 12v for power up the camera, the MCU pin 91 it's the control for this, but can't connect direct to 12v of the camera, we need a power mosfet.

Here the schematics of MCU:

Screenshot_2017-08-27-17-15-46 by Hugo, en Flickr

Solder the cable to pin 91 (be carefully pins on MCU are tiny you can easily short two or more pins)

IMG_20170823_193110 by Hugo, en Flickr

Now here schematics and board for connect camera and 12v control:

The lines are from the camera I already buy a cemara without lines but I'm still wating for arrive.

I made the control with LMUN2211LT1G and AO3407 because I already have this transistors but there is many option.

I include eagle files for board.
[MTCD  Android Head Units Q&A] apollo1976:
WOW !!!

This thing is awesome !!! It is very much that I was trying to figure out how to connect a front cam.

Thanks for this information !!!

But I'm not very experienced in these things.

I did a diagram of how I understood the connection to be made from pin 3, is it correct ???

I have to connect a wire from pin 3 to a 0.1uf ceramic capacitor and then connect the 0.1uf ceramic capacitor through a split to one 75 ohms resistor going to ground and on the other to a rca connector

Did I get it right??

Thanks for the support
[MTCD  Android Head Units Q&A] hugovw1976:
It's correct.
[MTCD  Android Head Units Q&A] apollo1976:
Thank you!!!

Tomorrow I buy everything and try it right away !!

You've been really brilliant, this thing is very useful !!
[MTCD  Android Head Units Q&A] hugovw1976:
Just remember you have to enable front camera in settings, and you can't power up the front camera with the same cable of the rear camera because is power down when unit change to front camera.
[MTCD  Android Head Units Q&A] techo91:
That’s very cool. I have two questions though:

1. How can we switch on the camera automatically? As long as I see you use it through the app.

2. Can this be applied to a MTCD KGL unit?
[MTCD  Android Head Units Q&A] hugovw1976:
1. The MCU pin 91, it's 3.3v when front camera is switch on, just have to add a PNP transistor to 12v to control the cam. Check the last pic the left part is the diagram of transistors switch to power up the camera, the right side is the connection of camera to video switch chip.

Solder the cable to pin 91 (be carefully pins on MCU are tiny you can easily short two or more pins)

2. Only have a GS unit to test this. but I bealive almost all units have same components just check if your board have the video switch chip FMS6502 and check if pin 91 on MCU 3.3v when front camera app is on.
[MTCD  Android Head Units Q&A] Xamadeu:
My GS Device has three camera inputs, but the front cam app does not work on any of them. Is there no possibility to change/mod the app? To take another existing channel instead of modding the hardware?
[MTCD  Android Head Units Q&A] hugovw1976:
Posible yes, but you must have to mod app and MCU software (MCU controll the video switch chip), I'm not a expert but I bealive mod app it's no very hard but for mod MCU software it's necesary to have MCU source code (not the compiled program that all vendors send to upgrade MCU) and I don't know if some ona have it. (and you must mod this with every MCU upgrade).
[MTCD  Android Head Units Q&A] xirix22:
In which directory eagle files for board.

Thank you
[MTCD  Android Head Units Q&A] bettuccio:
Hi, I would like to run my front cam from Fcam but I can not make the change. Alternatively I have attached the RCA AV wires but when I open the "Avin" application does not open at the first shot. I have to force the opening several times to view the images. Is there a solution? Another question: Can you modify the Fcam application for those who can not change the hardware? Which archive Fcam.rar is in which path to insert?
[MTCD  Android Head Units Q&A] hugovw1976:
At the end of first post is the fcam.rar file
[MTCD  Android Head Units Q&A] hugovw1976:
Unfortunately is not only to modify app you must need to modify MCU file and without the source code of MCU file I believe it's almost impossible, and I never see some one to share the source code of MCU file all I have is the compiled file.
[MTCD  Android Head Units Q&A] bettuccio:
I understand the impossibility. Why does apk Avin not open at the first shot? It's a software problem or current link because I've only done a test by leaning black and red threads without isolating them well. I wonder why the manufacturers have inserted Fcam if they knew it would not work! However, I would like to know the same way in which your "Fcam.rar" wires should be inserted. In the future I could use it if I cut my car radio. Now I'm only connected to an "AV in" extension in the dashboard and I take 12 volt power from a dismounted Dvbt receiver. From what I understand Fcam would not work that way. in addition to the modification You must connect behind the car radio to another source. Is that so?
[MTCD  Android Head Units Q&A] hugovw1976:
This shoud be a software trouble.

Just conect the camera to AV cable and the 12v output from the board (in the Fcam.zip) to power up the camera just when the Fcam app is open.
[MTCD  Android Head Units Q&A] bettuccio:
sorry I did not understand where the files in the "Fcam.rar" folder should be inserted. Can you please tell me? Thank you
[MTCD  Android Head Units Q&A] hugovw1976:
FCA.rar are files in eagle for schematic and board if you want to made board for easy connection but also you can solder components direct to wires.

For video input you just need 75 ohms resistor and 1uf capacitor.

And for power up camera (12v) you just need a NPN and PNP transistors with a couple of resistors. Check schematic on pictures of first post.
[MTCD  Android Head Units Q&A] bettuccio:
ah ok, now it's clear. I thought they were files to add to FCam apk. Thanks friend . ?
[MTCD  Android Head Units Q&A] bettuccio:
:dita incrociate:

hello, sorry for my insistence, in the end I opted for the Avin RCA entrance. Now I've resolved with Avin apk and it opens at the first shot. Now With a special application let me just unblock the Avin application that opens the front image for a few seconds

after the reverse . Now , however, I would like to know one thing: By doing various tests, I noticed that the wires that are connected to the 12 volt power of the car radio after a while are overheated. I would like to know if the current always circulates in the camera even when I close Apk Avin. I'm thinking this is why the threads are overheated. I'm afraid can burn. To avoid this problem from where do I have to take exactly 12 volt power?
[MTCD  Android Head Units Q&A] hugovw1976:
Yes the camera always drawing power that's the main reason for hardware mod. When you open the front camera app the MCU power up the circuit on the board I made to power up the camera only when front camera app is open.
[MTCD  Android Head Units Q&A] bettuccio:
in my case that I use Avin what can happen that I have always attached it to the power supply?
[MTCD  Android Head Units Q&A] hugovw1976:
I'm think you can short the life of the camera
[MTCD  Android Head Units Q&A] bettuccio:
sorry. How can I do this to prevent this? Is there any fuse or device to attack? I would always have it turned on. Alternatively I thought I would connect it behind the power of the reverse light so that it only activates in that circumstance. The problem is that I have already attached the rear camera there.
[MTCD  Android Head Units Q&A] hugovw1976:
If you connect the camera to the reverse light the camera only work if your car are in reverse, this not work for front camera.

You can install a switch to manual control the camera when you need it oterwise you need to made the mod on the first post.
[MTCD  Android Head Units Q&A] bettuccio:
Thank friend
[MTCD  Android Head Units Q&A] bettuccio:
hi hugo, I open this discussion again because I want advice from you. I purchased a 2-way box that changes the rear view to the front one after a few seconds. I thought that with this device I was passing your hardware change. I am not expert in the connections so I left the job to a specialized person but we could not make it work well. First we got the video source from behind the car radio but without success, then we attached it to the RCA Avin source and it worked well but the problem is that when the front view is closed, the power supply remains active. The duty of this box is also to disconnect the power supply after the front view has been displayed after 10 seconds. In addition to this the box has a button to activate the front view manually. What are we doing wrong? I put some a link, mine is the 2 way one. if you understand how to do it, can you help me in the links? Thank you .

[MTCD  Android Head Units Q&A] hugovw1976:
I believe something is wrong with the wiring connections. But the only way to know is if you made a wiring diagram of how is connected in your car and radio to check.
[MTCD  Android Head Units Q&A] bettuccio:
The specialized person has closed the connections because he was fed up. He had to abandon this project. He wants to install a delay timer but after that I will not be able to use any buttons to start the camera when I want it. Now I have found this 12 volt timer that you can put a button on. What do you think can be good to use in the dashboard of my car?

[MTCD  Android Head Units Q&A] hugovw1976:
Maybe work, but that isn't the solution. The module you install all ready have a timer why install another one.

There's two possible trouble with the module, or is bad wiring or the module itself is bad.

You must have to find another specialist.
[MTCD  Android Head Units Q&A] hugovw1976:
Also I believe the trouble can be a bad wiring on the reverse cable, your radio is connected with canbus module?

Because some canbus modules control the reverse input to turn on the reverse camera app. but this don't work if you install the module with the rear and front camera and you must bypass this wire and connect the reverse wire on radio direct to the output of module.
[MTCD  Android Head Units Q&A] bettuccio:
Yes, my PX5 has a CanBus PSA. The best wiring was when the switch worked and displayed the camera in the monitor but by measuring the current voltage with the tester, it was always active. Changing wiring, we realized that after the switch the front camera could not get power, the green screen came out, in fact with the tester it signaled almost 6 volts. There are 2 types of this device. I would not like to have bought the wrong one. The seller told me that this model I had was better than the other. My intention was to activate the front view after a few seconds from the back and close the circuit to not burn the front camera. In addition to this, I also wanted to activate the 12volt circuit from a physical button and close it when I wanted to. Unfortunately it did not work for me. Now the technician no longer has time to do other tests. I will put everything as before and leave this road.
[MTCD  Android Head Units Q&A] deliad:
Why do an hardware mod when you can do software mod that will catch the event and then show the aux av input??
[MTCD  Android Head Units Q&A] apollo1976:
I have done hardware mods and is perfect. now using the app F-Cam whenever i take off the reverse appears to me the front cam for 4 seconds and I can also use the entrance AV in for other things because it has remained free from the front cam. Perfect, thanks to hugovw1976 for its great help !!
[MTCD  Android Head Units Q&A] hugovw1976:
Simple, you have the A/V input free and software mod don't trigger power (12v) for cam only when you need it.

Built-in front camera connection

I was troubleshooting my rear camera problem and discovered surprisingly my unit has a built-in front camera connection and it works well.

See the picture below: there are two options in Factory Settings that front camera can be configured. My unit has a front view video input in addition to the one for rear view. When I connect my rear camera to the front view input, I can switch front/back views with a press to return button on the unit. Of course the back view was black when the camera was connected to front view input.

Since the option is in Factory Settings I wonder if anyone else has used it in real life.
[MTCD  Android Head Units Q&A] vassandrei:
Hi, thanks for the info, I’m gonna try it this weekend. This is the first time I’m buying transistors.. if I can’t find the ones you mentioned, is it just one pnp and one npn transistor? Or are there special specifications I’m looking for?
[MTCD  Android Head Units Q&A] hugovw1976:
For the NPN transistor most generics could work, and for the PNP just check how much current need your camera and buy one that can handle the current you need.
[MTCD  Android Head Units Q&A] vassandrei:
Okay. I’ve made a list here

Breadboard

(LMUN2211LT1G)npn transistor

(AO3407) pnp transistor

0.1uf ceramic capacitor

75 ohm resistor

47k ohm resistor

3k ohm resistor

RCA female plug yellow

Shielded wire (?)

Anything I’m missing? I figure I’ll mount the circuit inside the housing of the head unit and just have wires coming out.
[MTCD  Android Head Units Q&A] hugovw1976:
Shielded wire is preferred. And yes you put circuit inside head unit.
[MTCD  Android Head Units Q&A] pakoner:
Hi dear friends

On KLD, you can modify connector for rear camera...

Without any other modify. KLD already prepared

Work very well
[MTCD  Android Head Units Q&A] vassandrei:
What wattage are the resistors? Also I couldn’t find the npn one you listed, and I got the bc846b.. is that okay? I’ve literally never done this before and have no idea what I’m doing :)

https://ru.mouser.com/datasheet/2/258/BC846A-BC849C(SOT-23)-478240.pdf
[MTCD  Android Head Units Q&A] hugovw1976:
That npn transistor should work, for this purpose it does not matter the wattage of the resistance.
[MTCD  Android Head Units Q&A] vassandrei:
Okay... prepare for the worst job you’ve ever seen.

Aside from how terrible it looks... is everything in the right place? The red wire is where the 12v+ for the front camera will connect to. The blue wire is 3,3v+ pin 91. The yellow wire is 12v+ in, and black is ground. I’ve indicated the connections behind the breadboard in green.
[MTCD  Android Head Units Q&A] hugovw1976:
Those are some large resistors, Is hard to see in the small transistors but I think you mix some pins. Here is how must be connected. The upper one is PNP and bottom is NPN.

And I forget if you don't use LMUN2211LT1G you should add resistors to that transistor to, check datasheet of LMUN2211LT1G and you see the transistor already have resistors inside but yours don't have. Just add resistors like the ones connected to PNP and should work fine.
[MTCD  Android Head Units Q&A] vassandrei:
Ahhh! That’s another thing, I noticed that the npn one I got didn’t have integrated resistors. Okay, I’ll work on it some more. Also I just got a schematic for my head unit (it’s a Witson, MX series MCU if I remember correctly) and it might actually have pre-made connectors for fcam-in and fcam12v+... but they’re covered up by a piece of tape. I’ll check tomorrow. Anyway this is super neat and I’ll be excited when it finally works :D
[MTCD  Android Head Units Q&A] vassandrei:
Okay, update. On my WITSON unit there was a Second AV connector. Using the schematic that a Witson rep gave me got me nowhere and I basically had to use process of elimination to find out which pin was for the front camera. I used a multimeter to find out that PIN number 3 on the second connector was ground . (On the schematic it said fcam 12v was pin 8, Gnd was pin 4, and fcam cvbs was pin 7) Then, pin 13 on the main AV connector (labelled cam pow... nothing to hint it’s front camera) already automatically gave 12v when front camera was turned on, so it was fcam 12v. So basically after figuring that out I didn’t need to do any more soldering. Front camera works as needed. Now to get everything wired up. With the parking sensors too, and I’ll be set.

EDIT: So I've got it all installed! Works great. I wonder if there is a way to get the reverse camera to work manually as well (so, I could access it through the app and not have to shift into reverse.) Does the front camera power pin also stay on when I switch to the back camera in the f-cam app? Now I have to go investigate that too.

EDIT2: Yep. I should have given the rear camera/parking sensors power from pin 13 as well. Will change wiring. when f-cam or any camera module is open on the head unit, rear or front, pin 13 sends 12v+.
[MTCD  Android Head Units Q&A] ivellios:
Hey there!

I have a WITSON unit. It is for Ford Focus 2015 PX5 Android 8.0.

Crystal says there is no f-cam input. I use AVIN application for front camera but it cuts my audio out.

What is your model? Do you have the diagram with you? I am scared to open and do soldering to box.
[MTCD  Android Head Units Q&A] vassandrei:
You don't have to open the actual head unit, or do any soldering. Check if there is a small 8 pin connector next to the large AV connector on the back. one of the pins on that little connector is your F-Cam in.
[MTCD  Android Head Units Q&A] ivellios:
Thanks for the feedback. Unit is installed to vehicle at the moment. I hope It is not a problem to remove the unit due to the plastic quality, i am a little afraid to remove it :)

Where did you find connector to fit this 8 pin? Can i buy from somewhere?

Also do you have squeak rattle noise coming from head unit when it bad roads? How to solve this issue, with some foams maybe? Sorry for being off topic.

Regards,
[MTCD  Android Head Units Q&A] vassandrei:
I don’t have any squeaks or rattles but I’m sure you could get some adhesive foam, cut it to size and stick it on the outside bits of the unit that are hidden to prevent it. The connector is small, I’m not sure what they’re called but look into female motherboard header connectors (something like a motherboard header connector(?) would probably do.. I just had one lying around and cut it to size. Best bet is to see for yourself and check a local electronics store or market)
[MTCD  Android Head Units Q&A] johnpullen:
Where can you buy that harness?
[MTCD  Android Head Units Q&A] vassandrei:
I had a chance to take the unit out. You can see in the pictures the second mini connector I had to make and the pins I used. The black one is ground and the white one is fcam in. I also made another pin for fcam 12v+ but it ended up being pin 13 on the large AV connector
[MTCD  Android Head Units Q&A] pakoner:
You can ask your seller
[MTCD  Android Head Units Q&A] johnpullen:
Oh thanks I hadn’t thought of that
[MTCD  Android Head Units Q&A] Ben.suffolk:
I did that, and they simply said it was not a feature they supported. So I'd like to get that cable from somewhere. Which supplier did you use, maybe they could sell me one?

[MTCD  Android Head Units Q&A] pakoner:
If your product is KLD, you can modify the cable like in picture
[MTCD  Android Head Units Q&A] Ben.suffolk:
I have tested the pins with a multi meter and can confirm they are all correct as per your colours.

I just need to get some pins that will fit in the connectors. May use the audio out ones as I don't have an amp for them to plug into.
