You misunderstood - edding7 complained that they do not make a model specific for a BMW 1 series, so I suggested he ask the factory to make a BMW can bus model with a universal front, I did not say "a universal can bus" I said a "universal model with can bus".

edding7 - ask the factory to make you a BMW can bus model with a universal front !!

Does anyone use there unit with a permanent 3G connection? How does it function with regards to google maps. Etc.

Also, anyone using google now in the vehicle? I love using my PC to search for something, leave the office, and my cellphone already has the directions.

This looks like a nice unit. I like the detachable screen. I wonder how good it is otherwise?

[MTCB Android Head Units Q&A] tomc99:
I did find a capacitor linking the BT module on my JY unit, but removing it didn't give me the results I needed, so that's when I moved to cutting the leg on the BT module.

I seem to get some bias at the microphone socket - maybe a little low, from memory around 1.7 volts, but no audio whatsoever.

A little bit of a mystery to me is that after cutting the leg on the module the internal mic is now virtually clear of all buzzing that was evident beforehand.

I may spend a few hours this weekend and set it up on my bench power supply and have a better play with it.

Are you using an USB camera? My JY unit only has rear camera, and that rear camera is only active when the rear camera trigger wire has 12v on it. Otherwise it is a black screen.

My original problem was an ugly pink screen on my USB camera. That was solved with the Android update to 4.4.4.

After the update, I got a good picture, but it was jumpy while recording. This was solved by using a different car DVR program. All the programs I tried from the play store at least had a picture displayed from the USB camera

That sound great! Thnaks!

With Poweramp I was wrong. I made some tests today and I have to say, Poweramp resumes from the last time position if I close from the notification bar and then start with the PA shortcut. If I press the MODE button on SWC it plays from 00:00 the last song. This is just for me?

Is it means an USB webcam works as an inbuilt camera in my phone? I ask it because there are some apps what can adjust screen brightness about the phones front or back camera. With this we can make a real auto-brightness thing. Here are some apps:

Quick question cause im not sure now.

My unit is GS. Default android 4.2.2

Ive downloaded this rom: 4.4.2 JY_KitKat_2014-12-21 from google drive from this topic.

It upgraded without any problem with the update.img but the question is: does it have matters that android is from JY and my unit is GS?

After update steering wheel stopped working and the buttons on the unit (volume) doesnt work properly. Also theres issue with SD cards.

Can i downgrade to 4.2.2 ?

Android 4.4.4 on Huifei KGL w/2.02 MCU (BMW version)??

Hi

This may have been answered before, but having read through the posts I could not find it.

Is it possible to install Android 4.4.4 on a KGL with MCU 2.02 (or other MCU) ?? My unit is a BMW version w. SWC, 800x480.

If so what version should I choose, there seem to be several floating around. Obviously 800x480, but I have seen KLD, JY, GS and Klyde???

Thankfull for any assistance .

This will be useful for offroading, etc.
[MTCB Android Head Units Q&A] whbbrasilusa:
Yes you can, update only the update.img from any unit it is just android party

But if you decide to update the mcu it must be for your unit because it is the other system part and they are different between units. You can go on 800x480 first if it does not give you a good screen fit you can install the other.

Sorry to bother all of you again, but i am still having an issue with my HU. My screen stays black and the HU won't turn on again. Is there a way to connect the unit to the computer to flash everything from there? My unit has no front usb.
[MTCB Android Head Units Q&A] RyanBRZ:
Look in the first post of this thread. You download an app and click root and it does everything for you.

Or

Download and install a firmware that is already rooted.

Do you know if it is powering on (can you run radio/music app so you can hear music playing)?. I had a similar issue where the screen was not powering on but the unit was still working and able to play music. After multiple attempts of booting I was able to get it to light up, when it did I flashed a new firmware and MCU by putting sdcard in GPS slot and it fixed the issue. Did you try using the reset button or disconnecting 12v constant?
[MTCB Android Head Units Q&A] swanie2000:

[MTCB Android Head Units Q&A] parazit26:
I can't really say if it's powering on or not. But i would say no. My unit is at home and i connected the unit to an power adapter the same way as i always did (red+yellow wire 12V and black ground). When i do this nothing happens. If i use a usb flash drive with an indicator light and connect it, the light is not flashing. Since i have no fron USB, i asked my seller how can i connect the HU to my pc and he said that i should use the lower usb port on the rear side. So i connected the unit to my pc and suddenly the dvd drive started to make noise and the indicator light of my flash drive started to shine but the pc still didnt recognized the unit. I tried this combination to with power on + reset etc. but it didnt help. Right now i am thinking, that the mcu is dead because the front buttons don't shine and dont work because this all happened while i was updating to 4.4.4. The screen freezed and became blurry so i wait some time and pressed the reset button and ever since, the screen is black.
[MTCB Android Head Units Q&A] agentdr8:
You can't install a privileged (system) app in a normal fashion. You have to remount the /system partition read/write, remove the existing launcher from /system/priv-app, and place your old launcher apk in there, change permissions to 644, and root.root as owner/group. That's assuming the apks are all signed with the same private key, which more than likely they are, but you never know. All this can be done from ES File Explorer if you have root on your device (which you should if you use any of coudu's roms).

Hi, did you order this unit?
[MTCB Android Head Units Q&A] peti007:
Do you send it when Poweramp starts or when close?

When PA plays music, I press HOME button on the HU, PA goes background (music keeps playing), then start the radio with shortcut, PA pauses, radio sounds. Then when I start PA, music paused at the last time postion, when I hit play, it starts playing the last track, from last position.

So I think the "play/pause" signal have to send just when PA starts.

A small update on sniffing the the connection between the CANBUS decoder and the head unit.

Hi agentdr8, not sure if I'm just a corner case but for some reason when I was running version 1.3.1a of XposedMTC, I would get no sound from BT phonecalls. I have since upgraded to the latest 1.3.1g and it's all working fine. Would you have any clue as to what might have been the cause as there doesn't seem to be any mention in your changelog or from other people's experience in this thread.

Had to revert back to JellyBean as I initially thought it was an issue with KitKat but alas, after I restored all my apps and the problem resurfaced I finally figured out it was XposedMTC causing the problem ><

That should probably read App Settings, not XposedMTC.

That is true. No one has found a valid root method for a headunit running a stock KK rom. Luckily, the update.img files that the mfgs provide can be unpacked, and the files needed for root access can be injected into the image and then repacked prior to flashing, thus giving us rooted roms.

Hey guys, I mentioned in an earlier post about leaving the sub mono rca alone and only using the front and rear rcas to power my 2 amps. The front rca are Y split into my 4 channel amp that powers my front and rear speakers. The rear rca brings sound to my sub amp. I use the gain controls on the 4 channel amp to fade front and rear. I then use the field (fade)settings from the HU to even out the sound as i like it. I now have as good or better sound in my van as I have ever had. It takes a little time to fine tune the sound, but once you have it done you will be glad you took the time.
