Hi guys,

Found this Android 4.2.2 HU on ebay store but i not sure there is compatible with firmwares and patches on this thread?

hello is it possible to make one for mx player? so it starts on boot and plays?

Thank you
[MTCB Android Head Units Q&A] tolymatev:
That looks like a klyde unit, looking at the radio app and music. If I had to guess it would of been a yes it will work with the stuff in this thread.

Hope some one else will be able to confirm.
[MTCB Android Head Units Q&A] giornistrani:
I managed to get into the factory settings but it is not an option for CRUZE, there is only MAZDA & OPEL. I read in some posts that Astra J is GM ... I can select that option?
[MTCB Android Head Units Q&A] matekhr:
You can try different options until you find the right one.

BTW, what kind of canbus decoder do you have?

If it is "Raise", select GM (Raise) option.

GM (Hiworld) What is it?

Do you know if coudou's 4.4 breaks the radio? ive read people that have updated to 4.4 the radio stops working.

I have the eonon ga5153 unit and few of the memebers on http://www.golfmk6.com/forums have this also and after updating to 4.4 the radio stops working. I would like to upgrade but not at the expense of losing radio.
[MTCB Android Head Units Q&A] typos1:
Yes, its a KGL/HuiFei unit, only KGL use that front, it doesnt have 2Gb of RAM though, only 1Gb.

AS its 4.2.2 the apps shown are the 4.2.2 apps, ALL units running 4.2.2 used those apps, including the radio, not just KLDs

---------- Post added at 11:56 AM ---------- Previous post was at 11:55 AM ----------

Then it sounds like you need to update your MCU, what version are you on at the moment ?

---------- Post added at 12:04 PM ---------- Previous post was at 11:56 AM ----------

Not for most people, I have heard a few people say their radio broke after the upgrade.

Recently someone complained about this, but after investigation it turned out that they had not read the fist page correctly and they also updated their MCU at the same time using an MCU update that didnt match their unit (you can use ANY Android version on your unit from any of 8 or so manufacturers of these units, but you ONLY use an MCU update from the manufacturer of your unit, eg only KLD MCUs on KLD units) and this is why their radio did not work and I strongly suspect most people that complain about the radio breaking after upgrading have done this and that thats why their radios stopped working.

Less often I ve heard that the radio settings changed after the update. To change them back to the correct settings, go into factory settings (password 126) and try all the radio areas and all of the radio IC types (TDA7706, NXP6624, TEF6621 etc).

You dont have to be too worried though, as downgrading to your previous version is as easy as upgrading, so just try it.
[MTCB Android Head Units Q&A] ga!nusha:
Do you guys kave the release notes for the MCU's ?

I have seen that for KLD i have 2.0 and the latest is 2.4.
[MTCB Android Head Units Q&A] giornistrani:
Hello friends this is my current situation. I tried all the options in the "System Settings" and steering wheel controls do not work anymore. Tell me please what Rom install and MCU which should I use? Thank You
[MTCB Android Head Units Q&A] typos1:
No, there are no release notes, just try updating, if theres a problem, downgrade.

---------- Post added at 12:59 PM ---------- Previous post was at 12:57 PM ----------

Try the latest KGL5 MCU, the ROM is irrelevant. SWC is controlled by the CAN Bus adapter.
[MTCB Android Head Units Q&A] giornistrani:
In the third picture you can see that I have already installed the MCU KGL5 v2.22 ... and this is the latest version:(
[MTCB Android Head Units Q&A] v1ks:
Thanks for the detailed explanation mate, that explains why people end up having issues.

If i installed the OS without updating the MCU that should be ok then i guess? or do we need to update the MCU (of course to the relevant one to my unit) in order for 4.4 to function properly?
[MTCB Android Head Units Q&A] typos1:
No problem (all the info is on the first page). You dont have to update the MCU for 4.4.4 to work, it should work with the oldest MCU version all the way up to the newest.

---------- Post added at 01:37 PM ---------- Previous post was at 01:36 PM ----------

And there is no Chevy Cruze or GM Raise option ??
[MTCB Android Head Units Q&A] giornistrani:
CRUZE is not present, there is only CHEVROLET and GM (Raise). I tried them both and it does not work. I do not know what to do, I'm desperate:(
[MTCB Android Head Units Q&A] typos1:
Try all of the CAN Bus options and see if any works.

At every setting I have to reboot the device Android?
[MTCB Android Head Units Q&A] maan2304:
Hi giornistrani,

are you sure, that "KGL5" -xxx was the original MCU-version? As far as I know, KGL5 is often for BMWs, this could explain, why there is a strange behaviour in GM/Opel/Vauxhall or whatever cars.

Yours Markus
[MTCB Android Head Units Q&A] giornistrani:
You know what would be right for me? Thank You
[MTCB Android Head Units Q&A] maan2304:
No, but there are many users with wrong MCU-update and therefore strange behaviour of the radio...

Strange thing beside: your vendor told you to update with an Android version ....KDL.... and MCU .....KGL.... This is normally no problem, but especially the MCU-version has to fit to your radio's hardware, MCU is not interchangeable between brands (there are actual 6 or so). Do you have a screenshot from or do you remember the original MCU-version?
[MTCB Android Head Units Q&A] typos1:
Good point maan2304.

Go to the MCU download page and try all the non numbered KGL MCUs (ie just the KGL MCU Vx.xx and not the KGL1/2/3/4/5 MCU Vx.xx, giornsrani

Hitting "apply" should to enable new settings.
[MTCB Android Head Units Q&A] giornistrani:
no unfortunately not. The seller sent me mail with this MCU but not good

---------- Post added at 04:34 PM ---------- Previous post was at 04:26 PM ----------

to install the file mcu I reinstall the rom the beginning?
[MTCB Android Head Units Q&A] typos1:
No !! Read the first page !! Put the MCU.img file on an SD card, put the card in the GPS slot and press "OK" when prompted.
[MTCB Android Head Units Q&A] giornistrani:
guys I found the screenshot:) where do I find it? In the list there
[MTCB Android Head Units Q&A] uncleg:
MCU is for HU model, not for proper car model. If you flash mcu from other HU model (GS, KLD, KYD, etc), you'll have not correct working front panel buttons. In sum, if you have KGL5 from factory by default, you wiil need the equal (KGL5) MCU's images in the future.
[MTCB Android Head Units Q&A] typos1:
You misunderstand, we think he may incorrectly have one of the KGL numbered MCUs on his head unit and that he should have a non numbered KGL MCU.

---------- Post added at 03:51 PM ---------- Previous post was at 03:49 PM ----------

You earlier screen shots showed you running Malaysk's ROM and KGL5 MCU, now you are running a different ROM and have the non numbered KGL MCU v2.21, so you have updated both. Has it worked ?
[MTCB Android Head Units Q&A] RyanBRZ:
I checked and realized i accidentally upgraded with KGL instead of KLD. Is either superior or is it just the layout that is different?
[MTCB Android Head Units Q&A] uncleg:
But I saw on his screenshots. He has KGL5.
[MTCB Android Head Units Q&A] typos1:
As youve been reading this thread for a long time Ryan, I thought you knew that you could use an Android version from any manufacturer (KGL, KLD, GS, JY, RM etc) that you want on these headunits !

Its entirely down to what you fancy. I would try them all and use which ever one you like best. Its just layout and style that differ really.
[MTCB Android Head Units Q&A] giornistrani:
The photo is of Rom who had initially, then the seller made me change rom and MCU because I wanted a red ROM. . Initially, with the Rom blue, steering wheel controls work well now with this no. The MCU file is indifferent to all the Rom?
[MTCB Android Head Units Q&A] typos1:
Yes, but now he has KGL v2.21 !

We think he may have been given the incorrect MCU by his seller and that he should not have a KGL numbered MCU.

EDIT: and now it looks like he IS supposed to have a KGL5 MCU and NOT a non numbered one, its hard to keep up, maybe its because English is not his first a language plus the fact that he hasnt read the first page and his seller gave him an incorrect MCU

---------- Post added at 04:03 PM ---------- Previous post was at 04:01 PM ----------

Yes, the MCU and ROM are different !! PLease read the first page, translate it into Italian if necessary, do this BEFORE you do anything else with your unit !!

The ROM makes no difference to anything MCU related, you can change that later.

So, with the KGL5 MCU the SWC worked, is that correct ?
[MTCB Android Head Units Q&A] giornistrani:
Excuse me guys I'm Italian and Use google translator, sorry for my bad English. I think he's right typos1, maybe my seller gave me the wrong MCU. Where can I download the file right? The list can not find it. Thank You

I mentioned last week that Klyde will be making RK3188 quadcore versions of these units, now KGL have put their RK3188 versions as "coming soon" on their Alibaba site:

http://kaigele.en.alibaba.com/productlist.html
[MTCB Android Head Units Q&A] giornistrani:
KGL V2.18 there isn't in the link that gave me
[MTCB Android Head Units Q&A] typos1:
Why does that matter ?

This is getting confusing, please confirm whether the first picture you posted with the green colours and the KGL5 MCU worked or not.
[MTCB Android Head Units Q&A] giornistrani:
No, green color does not work. Blue color works. I need the MCU V2.18
[MTCB Android Head Units Q&A] RyanBRZ:
I know that... My question was is there any technical/functionality differences between KGL/KLD or is it just aesthetics/layout differences? Which you've just answered. Thank you
[MTCB Android Head Units Q&A] typos1:
Right, previously it appeared that it was the otehr way round.

You do not need the KGL v2.18 MCU, you need a non numbered KGL MCU, preferably the latest version, so simply install the latest KGL MCU that is in the link.
[MTCB Android Head Units Q&A] giornistrani:
ok I try, thanks typos1 and sorry again for my English ...
[MTCB Android Head Units Q&A] uncleg:
Oh, now I see :)

But anyway, main key of my reply for him, is for future information about MCU's and their main target.

Not for car model, but for the right HeadUnit usage, only. :)
[MTCB Android Head Units Q&A] typos1:
Ah right, well there are - KGL has separate widgets for radio/music/ipod/BT etc, whereas KLD and JY have built in widget-like displays that automatically change between radio/music/ipod/BT etc depending on which you are using. KLD and JY alsohave a "car app" button, KGL does without, some people have said that the KGL versions sound better, there are also minor layout differences - KLD has a red theme to its apps, KGL and JY have mainly white. Also KGL has a strange phone pad - its laid out different to any other phone key pad in the world, being sort of on its left side, with "0" being in the middle on the right instead of in the middle at the bottom as normal phone keypads. Thats all I can think of for now, I d just try all of them and pick what you like best.

---------- Post added at 05:04 PM ---------- Previous post was at 05:02 PM ----------

Oh but wait, hes changed it again, KGL5 is wrong AHHHHHH ! lol.

Fair enough, always good to confirm correct usage, especially for people who dont read the first page, mind you we re up to 1000+ pages now ! :crying:

I downloaded this file MTCB-KGL-V2.09, I plugged in SD, I added to radio on and nothing happens. How should I proceed?

There are two ways:

1. do a complete update with update.img and mcu.img on your sd-card

or

2. boot to recovery mode (read post #1) and install only mcu.img from there

Hello friends,

I think I found my ignition problem on my car radio.

Some wire does not match the pattern on the car radio.

In the photos you can see there are 2 wire not the right color then I think they are not well placed.

I dare not inverted because there are + 12V on the pink and not the orange / black.

Do you have any idea?

Do you have a picture of your wiring so that I compare?

I'm from Belgium, please excuse my English
[MTCB Android Head Units Q&A] typos1:
The reverse wire is for the reverse camera and the brake wire is for connecting to the handbrake ground so the headunit knows when you are moving or not, I dont think either of those would affect the igntion.

Your problem is that the car language has changed, is that right ?

If so how would you normally change the language on you car ? I can change the language of my car from the dash board, are you sure that you cannot do that on yours ? Have you checked the handbook ? I m tempted to say as was suggested yesterday that you have to go to a dealer or have some special software to do it, but for the fact that your headunit has done it.

I think I killed the bluetooth module on my KLD head unit. I removed the C32 capacitor next to it, along with soldering a mono 3.5mm jack to MIC+ and SGND. I checked my connections for continuity. Seemed fine, but now it doesn't look like bluetooth initializes. The Bluetooth app doesn't show anything for the name/pin and when I try to change them in Settings, Settings crashes. Anyone know what I might have done? Does anyone know where to get a replacement?

Did you get a magnifying glass and check for solder bridges? If you are using no-lead or low lead solder, it's very, very easy to get small bridges. Also, did you clean the flux off the board after soldering? Did you accidentally cut a trace?

Lately, I have been taking pictures with my phone and zooming in.
[MTCB Android Head Units Q&A] matekhr:
I suspect you have some problem with your canbus decoder and/or settings. Can you post the picture of the label on your canbus decoder?

Does any of central console buttons work? How about HVAC (air condition) commands/buttons? Can you hear the system sounds (door open, lights on, turn signal etc.)?

[MTCB Android Head Units Q&A] webdude12:
One other side note. I did disconnect the Reverse wire from the back of the radio. When the radio is in "Rear Camera" mode, all sounds stops. This needs to be fixed. As I currently do not have a rear view camera. It was simply looking at the radio wiring diagram and snipping that one wire.

Not sure how quickly you want this unit, but Im in talks with the manufacture about becoming a US distributor for them. I am starting a side business, that having a product line like this kinda makes sense. But really wanting to see what they are doing with root, and the few requests before I commit.

However if you really want it, I am setup to take credit cards now, and can ask if they will sell me 1 unit. Just not sure I what pricing I will get on it.

Is there not a setting to keep sounds on on reverse like on the AN-21 and OUKU? I would be interested to see what settings pages are available and what possibilities they offer (SWC, front panel buttons, sound settings etc.)
[MTCB Android Head Units Q&A] webdude12:
No there is not a settings, nor is there is a setting to re-map the hard buttons on the front of the unit (outside of the GPS button, but even this has it limitations, has to be an app you install, so can not link it Google Maps, since we can remove it without root and then re-install). Although that would be great. :)

Maybe Keylo can chime in on this as well.
