I d update your ROM now if I were you. :)
[MTCB Android Head Units General] efrasjourney:
Yeah, already did. I'm in Malaysk ROM :D
[MTCB Android Head Units General] typos1:
I meant to 5.1.1 there may be probs with the latest MCU but an older Android version.

I have seen KSP MCU v.2.98 (the latest one on this thread is 2.89) from the new HU on my friend KIA car.

How can I extract that MCU file? Or where can I download v.2.98 for KSP
[MTCB Android Head Units General] typos1:
Theres no known way of doing it, but you could contact your seller and try and get a copy, then I can upload it to the fileserver.
[MTCB Android Head Units General] StoneRoses:
The HU is on new car (KIA Carnival sold in Thailand). The car dealer seem to know nothing about the android head unit. :(
[MTCB Android Head Units General] typos1:
Really, theyre putting them on new cars ?
[MTCB Android Head Units General] hode2:
WhatÂ´s new?

Hello,

what´s new in "KLD2 v.2.81 factory"?I have no info found?

thx
[MTCB Android Head Units General] typos1:
There are no changelogs for MCUs, if youve recently updated the Android side, would be a good idea to update the MCU to the latest version.
[MTCB Android Head Units General] StoneRoses:
Yes. KIA Carnival (Sedona in the USA) have android head unit as a stock HU (KSP quadcore 800x480) I suspect it related to offline GPS apps for Thailand (HoodDude http://hooddude.com/Products.aspx#hooddude) It's has special version for KIA cars and installed on GPS SD Card.

Hi,

Is there any MCU update for KGL? Does 2.64 mod work with lollipop?

Moreover how to make button light sync with headlight?
[MTCB Android Head Units General] typos1:
2.64 works with all versions, but it is not the latest KGL MCU. Dunno about headlight sync, try it an see.
[MTCB Android Head Units General] oatja:
Hi typos1

Many thanks for your reply, about sync with headlight. It's sync with illumination wire. KGL MCU not sync even I turn on/off in this function except mod MCU.
[MTCB Android Head Units General] typos1:
Have you tried all KGL MCUs ?

[MTCB Android Head Units General] typos1:
Great, how did you do it, did you just re-flash a KGL MCU ?
[MTCB Android Head Units General] sayborg:
MCU MX

Hi,

I have also flashed the new MCU MX from v2.21 to v2.82 (I am not sure if I flashed it correctly but at least in system/about it displays v2.82) and now the radio is muted. How do I solve this issue ? Everything else works fine.
[MTCB Android Head Units General] typos1:
Go into factory settings and make sure the radio tuner is set to the correct type.
[MTCB Android Head Units General] sayborg:
Thank you for your help but I went into the factory settings via the password '126', entered into a new menu, under the RADIO tab, Europe was already selected, therefore I didn't change it (because I live in Europe). Under the APPLICATION tab, I see the radio settings which displays a drop down list where I see TDA7706 selected amongst several options. What should I select there ?

I have attached the screen shots...

thanks in advance
[MTCB Android Head Units General] typos1:
If you didnt make a note of what tuner you had before you upgraded and didnt save your MCU config so you could restore it after updating, then your ll have to go through each tuner type in the "radio" list and see which one works.
[MTCB Android Head Units General] sayborg:
Ok, thank you. So, you mean, under the APPLICATION tab, for the RADIO option field, I have to select the options one by one, right ?
[MTCB Android Head Units General] typos1:
Yeah, thats it.
[MTCB Android Head Units General] sayborg:
Ok thank you, I will try and report back...
[MTCB Android Head Units General] gianluca.barocci:
MTCB-ZD-V2.86 can you tell me what brand it

Inviato dal mio ALE-L21 utilizzando Tapatalk
[MTCB Android Head Units General] typos1:
Yeah, the brand is "ZD" hence the "ZD" in the MCU identifier.
[MTCB Android Head Units General] sayborg:
I have tried all options for the radio tuner. I have selected an option, clicked on 'apply' and 'exit'. The radio is still mute. Any suggestions?
[MTCB Android Head Units General] typos1:
Remove the top and check that the radio tuner is earthed (the earth cable has been known to come undone), re-flash the MCU to another version or simply reflashing the same MCU may help.
[MTCB Android Head Units General] sayborg:
OK, will do.

The previous version was working fine until I flashed it with v2.82. IfJust to be sure, how do I properly flash it again ?

I just want to be sure I do things correctly to avoid further issues... What are the step by step instructions ?

Thanks in advance,
[MTCB Android Head Units General] oatja:
I did but key light always on. :rolleyes:
[MTCB Android Head Units General] typos1:
You could play around with the CAN Bus type in factory settings.
[MTCB Android Head Units General] DJAVI2010:
Does anyone know where I can find mtcd_ht

No, but youre in the MTCB/C forum, youd be better off asking in the MTCD forum . . .
[MTCB Android Head Units General] Tisho85:
Hey hi,

This may be a long shot, but do you have dimming functionality on your car itself. The dash board of my car is quite bright so I'm dimming it, but then when I got the desired brightness of the dash board the illumination wire of the head unit is not getting enough voltage (I suppose?!) and the buttons of the HU does not light up at all. When I increase the brightness of the car itself, then the buttons come back online

PS: Sorry I just saw that your problem is that the lights of you are always on

I've got a mtcb-jy-2.86 MCU. Is it possible to install a newer mtcc MCU from kld?

Are there any improvements or is there no point in updating the MCU?

Thanks in advance!
[MTCB Android Head Units General] typos1:
NO ! - you can only install JY MCUs if you have a JY MCU, the ONLY MCU types that are interchangeable are BN and HA.

Its always good to update your MCU, but you already have the latest JY.
[MTCB Android Head Units General] anna_01:
2.86 MCU

I have mtcb-jy-2.86 MCU. I think it is the latest MCU for JY. But when I speak via BT connection only right passenger speaker is working. Not left driver. When reinstall to 2.73 all work fine. How to fix it in 2.86 MCU?
[MTCB Android Head Units General] typos1:
Go into factory settings and uncheck "rudder" (Chinglish for "right hand drive") then it should come out of the left hand front speaker, if rudder is not checked try checking it.
[MTCB Android Head Units General] anna_01:
Thanks, but I have done it many times. No results(
[MTCB Android Head Units General] typos1:
Hmm, not sure what else to suggest, I m afraid, sorry, seems like a bug. :(
[MTCB Android Head Units General] mbt28:
Can anyone tell me which mcu should I use for this head unit? I think I flashed wrong mcu my buttons mapped wrong.

Thanks.
[MTCB Android Head Units General] typos1:
Thats a Klyde launcher, but that doesnt necessarily mean its a Klyde unit, what was the MCU originally ?
[MTCB Android Head Units General] mbt28:
Actually it is a custom rom from malaysk. The problam I dont remember the original mcu. Probably I made a mistake but cant we figure out it from button order? Is there any other way?

Thanks.
[MTCB Android Head Units General] typos1:
Cant necessarily figure it out frhe button order as it could be the correct MCU but the button map settings could have changed when the MCU was updated, or it could be a "KLD" MCU and you flashed a "KLD6" MCU or something like that.

A picture of the back of the unit would help me identify your unit.
[MTCB Android Head Units General] mbt28:
Hi,

Thank you for your help. I will put here at evening.
[MTCB Android Head Units General] mbt28:
Here are pictures from backside of head unit.
[MTCB Android Head Units General] typos1:
Is that a "Hui Fei" logo on the motherboard at the top right ? If so you have a KGL.

When you say you "think" you flashed the wrong MCU, did you check what the MCU version was before you flashed an MCU ?

What MCU did you flash ?
[MTCB Android Head Units General] mbt28:
I flashed like a year ago KLD mcu, I think I just remembered wrong the original MCU and flashed that one. At left upward it is written:

Hui Fei

KGL -MAIN-90D-V2

2014-7-20

Which mcu should I flash?
[MTCB Android Head Units General] Roerbakeitje:
The MCU from JY version 2.87 on a 3066 device I can report that is not working well. Bleutooth connection lost and reverse camera error.
[MTCB Android Head Units General] RobRoy:
Hi,

Had to Reflash my MCU, lost touch screen and buttons.

Now touch screen works, some buttons work correctly, some have wrong assignment (execute wrong function) and some don't show a code when pressed.

Its a special radio for Mercedes W211.

Original MCU showed as:

MTCB-KGL-V2.55

May 19 2015 09:19:44

Menu = no key press registered, no function

Navi = key 51, works

DVD = key 45, need to remap

Mode = Key 46, need to remap

Mute = Key 4, works

Loud = No key, not working

Eject = no key, not working

AMS = Key 42, need to remap

"1" = key 43 , need to remap

"2" = key 73, need to remap

"3" = No key, Opens Home screen

"4" = Key 4, mute, need to remap

"5" = Key 19, need to remap

"6" = key 27, need to remap

Rwd = key 27, need to remap, clashes with "6"

Seek Rwd = Key 49, need to remap

Seek Fwd = Key 3, need to remap

Fwd = 52, need to remap

Play/Pause = Key 69, need to remap

Somewhere I read Merc should be KGL1 instead of KGL.

Any ideas?
[MTCB Android Head Units General] typos1:
What MCU did you update to ?

Why dont you try KGL1 then ?

---------- Post added at 01:23 AM ---------- Previous post was at 01:20 AM ----------

KGL, if you have a KGL, surprise surprise !!
[MTCB Android Head Units General] RobRoy:
Hi,

Is it safe to flash a different version/branch of KGL?

Also should I go to a later version covering all KGL branches (0-5) ?

If yes, which version?

Cheers
[MTCB Android Head Units General] RobRoy:
Hi,

Good news:

Updated to KGL_1_ 2.55

What works:

Screen

ALL buttons

Radio (after I change the radio to the correct one in the Factory settings)

What is not working:

GPS, Antenna connector faulty

Blutooth, after playing with blutooth in Factory settings, can pair, but always connects and disconnects, cant make calls or listen to music., will have to try the remaining BluTooth settings in the Factory settings, tried half so far

What I learned:

1. Dont believe when the MCU says KGL, it may well be KGL_1 or similar

2. Take a pic of ALL factory settings pages and system info pages as soon as you get the radio before you tinker or it crashes.

3. Be patient grasshoper.
[MTCB Android Head Units General] typos1:
If it says KGL it is KGL, it may be that you have to go t an older version, or that later versions only work with later firmware, or that later firmware doesnt work with earlier MCUs, or even later firmware only works with non numbered MCUs - most KLD numbered MCUs can be upgraded to KLD6 and KLD9 MCUs, although this doesnt apply to KLD non numbered MCUs, so it may be worth trying all the KGL MCUs listed here.
[MTCB Android Head Units General] mbt28:
However which version of KGL should I install?
[MTCB Android Head Units General] typos1:
Impossible to tell, your ll have to try different ones, I would suggest trying later versions of every KGL type first and seeing which works best.
[MTCB Android Head Units General] mbt28:
Now I flashed, KGL5 v.2.55 with sleep and redesigned sound processor from darkleo, everyting seems working but even if I choose rgb option I cannot see Elements application. What should I do?

[MTCB Android Head Units General] RobRoy:
Hi,

New (old) issue.

Second time my MCU settings appear to be corrupted.

One note: my battery is a bit low at times, need to replace eventually, wonder if the dip in voltage can cause the corruption.

From recollection same circumstances.

Key in ignition (not yet running).

Radio starts

I turn key to start car while radio starting

Radio seems to restart again

Some radio physical buttons stopped working correctly

Radio is no longer picking up preprogram stations as per mtc-radio.ini

Will reflash booth MCU and Android image again and reset everything from scratch.

Any thoughts?
[MTCB Android Head Units General] pa.ko:
Yes voltage drops can partially or fully erase MCU memory. These units don't have internal battery nor other protection. Some have possibility to keep power during short ACC voltage drop (requires later Darkleo modified or OEM MCU very). But voltage drop on BATTERY line is not amortized by unit itself.

There is some capacitor mod around which may help in cases of short drops. But, I would recommend replacing faulty car battery anyhow.

I had few times in year or so situation that for some reasons (disconnected my battery in car service for short time) MCU memory get messed up. First time I was scared and flashed both MCU and Android again and reconfigured everything and it was fine. Next time I flashed only MCU and not Android and it worked. In meantime I learned that you can save and reflash only MCU config. Didn't tried it myself but you can. Worth to check as you will save time on manually reconfigure MCU every time.

My dear friend hi. I read your response and it is an opportunity to ask and if the device which has factory MTCB KLD2 MCU can be upgraded in other KLD3, or 4,5,6 ..., and change will be any-more?

Thank you for your time :)

[MTCB Android Head Units General] typos1:
Its normally only "KLD" MCUs (ones without the number after the letters) that cannot use the latest MCUs, so KLD9 should wprk on your KLD2 unit, try it.

Good news indeed upgrade to MTCC last successfully KLD9 not lost on factory settings menu and everything is working well !!!

Now that when I spotted, shut the machine and make the car key lighting of buttons now stays open for approximately 30 seconds and then closes. It didn't ever seen with the MCU: KLD2 MTCB., and it is not a problem.

[MTCB Android Head Units General] pcmender2005:
Yes you can but make sure you have a copy of the one you already running. But first boot the radio up and goto factory settings code should be 126 and take a pic of all the settings in the tabs as you may need to reset them back after flash of mcu try this version MTCC-KLD9-V2.98.

Or simply use the MCU.cfg option which backs up your MCU config settings and then you flash it after flashing a new MCU.
