[MTCD  Android Head Units Q&A] homer.ali:
Hey guys,

After being inspired by this thread I decided to implement my own solution to this problem in order to have a working fcam.

While I've soldered a few times I certainly didn't feel confident enough in my skills to solder onto the chips as mentioned by OP. The risk of catastrophic damage to the tablet was too high for me given the relatively small benefit of having an integrated fcam.

My solution is an external circuit. Which requires no soldering on the expensive radio whatsoever.

Here is the circuit:

Explanation:

When you hit reverse, 12V goes immediately to relay 1 and turns it on. This allows the reverse camera input on the tablet to be connected to the actual reverse camera.

At the same time the 12V trigger goes into the RC circuit to charge the 100 microfarad capacitor. This turns on the npn 2n2222 transistor to allow the collector to connect to the emitter which turns on relay 2 by connecting it to ground. When relay 2 turns on, 12V(from the cars 12V ignition wire) goes through to the reverse trigger wire on the back of the car radio to tell unit to switch to the reverse video.

The result of reversing is what you'd expect; the reverse camera turns on and the tablet shows it. The magic happens when you switch back to park or drive-- the capacitor that was charged before keeps the transistor on which keeps relay 2 on for a few more seconds (about 3 with that configuration) thereby keeping the tablet on the video screen. Relay 1 however immediately turns off which connects the reverse camera input on the tablet to the front camera instead. This allows for effectively the same behavior that you would get from the mod described by OP in this thread without having to open or mod the tablet itself at all!

Hope this helped someone!

I have a KLD unit and have wired up a front camera by adding wires to the backup camera harness. Works perfect! Thanks for the tip that KLD was already wired for this.

Thanks!

[MENTION=6964181]hugovw1976[/MENTION], before starting this mod, did you check whether fcam (and 12v for fcam) is already connected to some of the pins at the back of your unit?

If yes, that would simplify things a lot...
[MTCD  Android Head Units Q&A] hugovw1976:
In my board the pins from the microchips where I need to connect video signal and the output signal for power up the cam don't have any connections. For that reason I solder wires directly to a pin on microchips.

But I know some units already have the connections for just plug and play the front camera.
[MTCD  Android Head Units Q&A] l3ft3r1s:
Thanks. So is a multi-meter enough to check if the microchips are connected with the pins at the back of the unit?
[MTCD  Android Head Units Q&A] hugovw1976:
Yes
[MTCD  Android Head Units Q&A] silviocross:
Hello, I'm sorry for resurrecting such an old thread.

I have a KLD MTCE unit (PX5) and I am not able to get FCAM working.

On the back connectors I already have the pins properly connected, and I verified the board already: I have a right connection to the pin3 with capacitor and resistor compliant to the schematics.

The 12V supply is correctly activated when opening the app, but I am not able to see anything on the screen. I tried 2 different cameras, they are working if I connect them at the reverse camera input.

I assume this is a SW issue, am I missing anything in the configuration settings?

Thank you and best regards

FCam

Model and Hardware: HF S8 Series H2061 (1024x600)

Android 9 HAL9K

MTCE_HF_V3.30_1

Build: RK3368-userdebug 9 PI20200106.145242 test-keys

First of all...I really appreciate this community! I was ready to throw it in the trash until I installed the Hal9K. It would lock up every 5 minutes prior to installing that ROM.

I have AV-IN that only displays on AV screen. I'm trying to run FCam.

I have 3 issues I'm looking for an answer to.

1. I've made it this far in my search and wanted to confirm I need to do this mod for my unit?

2. While running FCam if I set in to rear cam I get a very distorted image. If I unplug the cable and plug back it it's perfect. If i switch front to back the video is distorted again.

3. While my unit is cold, I will get a black screen and lose audio for a second. Sometimes my backup camera will display for this sort second. Will happen 2-3 times. Once warm I don't have this issue.

I really appreciate this community! I was ready to throw it in the trash until I installed the Hal9K. It would lock up every 5 minutes prior to installing that ROM.
[MTCD  Android Head Units Q&A] honasvocas:
hello, trying to revive this post...

Id like to have a front cam recording (aka dvr unit).

I have kroak K-cs01 unit which is basically F9212B and have it connected to rear camera and front camera.,

Front camera works with AVIN app no problem. What I want to know is if theres a way of connecting it as a DVR to be able to record the route all the time?

I was thinking of adding this module from AE:

HD CVBS to USB UVC Drive Free OTG Module AV to USB Camera Module Fishing Car Monitoring

or this more expensive one:

New video capture card AV signal to USB camera H264 hardware encoding UVC drive-free OTG

Anyone has experience with these modules?

It basically converts CVBS camera to usb and to my understanding it should work in FCAM then...

Hello guys, i did successfully this mod few years ago but now i’m thinking to change my front camera wich is cheap ccd/ntsc low quality and i want to upgrade to a better quality one like AHD1080p PAL , anyone knows if Dasaita PX5 4gb ram 2017-2018 model support AHD camera for front mod ? In the unit settings/ Factory settings i did not find anything about Fcam or Rear cam output format or resolutions , just enable/ disable .. fcam , rear cam or how many seconds triggered..

I forgot to mention , for rear backup i have an 2011 eom vw flip badge camera since i have this android unit and works flawlessly with this dasaita.
[Huawei Mate 9 Questions & Answers] mscion:
Hi. Like many, I bought a Chinese version of Mate 9 (MHA-AL00) because it has superior specs. Unfortunately, the phone was dropped and I now have a small crack in screen and scratch on bottom side near speakers. What is the best way to get this repaired? Is there any place in the US that will service this phone? I contacted Huawei in US and they won't touch it. I asked if they could order the parts and have it fixed. I will pay for it and they said the phone is too different for them to repair. The reasoning escapes me here... Any help here would be appreciated! Thanks!
[Huawei Mate 9 Questions & Answers] Swan Princess:

[Huawei Mate 9 Questions & Answers] mscion:
Hi. Is this genuine Huawei parts? Also is Huawei logo on front? By side rim I meant the outer side of frame. Like along where the speakers and buttons are. Thanks!
[Huawei Mate 9 Questions & Answers] Swan Princess:
Do you want your phone fixed, or have genuine parts? I've not seen genuine Huawei parts outside an authorized Huawei repair shop. My replacement screen works though and looks mostly like the original did. Outer frame can be found there as well probably, but I haven't looked yet.
[Huawei Mate 9 Questions & Answers] mscion:
Well, both actually! I want the phone fixed using genuine parts. Currently a Chinese friend is kindly contacting Huawei in China to see if I can mail it to an authorized repair shop there. Unfortunately Huawei US won't touch my phone. I don't understand why Huawei US can't just order the parts from China and fix it for me in US. I can't believe the variants are that different structurally and I'm willing to pay the cost.
[Huawei Mate 9 Questions & Answers] Johnsonyc:
Different region have different policy for their phone if there no different why they need to be sell on different model and version as International or Chinese / Asia / Europe. When you buy the chinese version you should know it will not cover any warranty beside Huawei china. Yea because you save few dollars for buying the chinese version and you want to enjoy the full international version benefit? You get what you pay is that hard to understand?
[Huawei Mate 9 Questions & Answers] mscion:
;

Hi. I think the misunderstanding is on your part. I bought the Chinese version because it has better specs than the one one sold in US. More ram and more memory. Better meets my needs. Not because it is cheaper. Btw, it was more expensive. Second, I fully understand that warranty does not cover Chinese version outside of China. I have been in contact with merchant that sold phone and they can send it to have it repaired by manufacturer. Just want to avoid having to send phone back to China. Would prefer to have official parts mailed to me and have repaired here in US. But to be clear, I am not asking for repair that is covered by warranty. I am asking about a repair that I will fully pay for. Is that hard to understand?
[Huawei Mate 9 Questions & Answers] :
I'm looking for a way to send my phone to China for warranty from Europe. If you have any information or know a third-party that can arrange this, that would be of great help. Thanks
[Huawei Mate 9 Questions & Answers] mscion:
Hi. Your question is the point of this thread! Hopefully we will have an answer we are happy with. I'm still checking on possibilities. I originally bought my phone from Geekbuying. They have offered to send it back to manufacturer for repairs. So you might consider contacting the merchant you bought it from. I am still waiting to hear from my Chinese friend. Once I know more I'll post what I learned.
