[MTCB Android Head Units Q&A] jkchr1s:
I did use a PAC adapter I bought from best buy until the new one arrived. But to make it work, you have to power the unit up and change the canbus settings in the factory settings menu to "no canbus." My wiring harness only had a key2 wire, but you need key1 and key2 wires to make the steering controls work. I was able to use my unit until the replacement came in.

To get it to temporarily power up for the PAC adapter, I used a wire to connect the battery wire to the accessory wire, then changed the canbus setting in factory settings.

Edit: it should power up without this just wiring up the PAC adapter. You will have to press the power button after turning the ignition on the first time to change the canbus setting. Just be sure to switch it back to what it was out of box before swapping out the PAC adapter for the Chinese one.

The sound quality actually sounded much better with the PAC adapter than it did with the Chinese canbus adapter. I had to choose between SWC and sound quality. I ended up getting a Newsmy stereo instead (rk3188 quad core) and was much happier with it. It had much better sound quality with the alpine audio package and a larger screen. The mixer of the heifei unit never sounded quite right with the factory alpine amp. The newsmy unit sounds amazing with it.
[MTCB Android Head Units Q&A] DiGi91:
Thanks for the help man, So I could just leave it without the canbus and there is no issues? I have the PAC CP5 Steering wheel control module and the unit I bought is the 4.4 quad unit. I attached some pics or the fact it came with 2 harnesses (1 with the canbus adapter and 1 without it) also only seeing key2 on both of the harnesses.

EDIT: So I won't be able to use steering wheel controls with the CP5? =/ this is ****ty lol

[MTCB Android Head Units Q&A] jkchr1s:
Yeah, if your harnesses don't have the key1 and 2 wires the SWC won't work with it. I used a different PAC adapter, PAC C2R-CHY4 that handles the factory amp. Not sure if yours is the same or not. But it will power up and work with a PAC adapter.
[MTCB Android Head Units Q&A] DiGi91:
Hmm that sucks.. I'm having a shop do it because I don't trust myself doing this **** and I've had them do my other installs on my older vehicles. So how does the wiring change adding in the PAC module? Thinking maybe I should wait to see if I can get the right canbus adapter and then go but not sure.. I'm impatient and I want this thing installed now lol. I hate the stock jeep radio!! The PAC you used was for premium sound I'm guessing? I don't have anything fancy in my PAT just 4 speakers and no sub and to my knowledge no factory amp.

do you lose anything else bypassing the canbus?
[MTCB Android Head Units Q&A] ProGEEKNZ:
No sound after boot

Im running Malaysk's latest build, and I have an issue where the system will boot, Sound for a split second and then its gone, Pressing either of the volume buttons seems to restore sound.

Any ideas ?
[MTCB Android Head Units Q&A] Malaysk:
Try disabling the program MTCServis (Car) - establish a secure volume when loading.
[MTCB Android Head Units Q&A] ProGEEKNZ:
That was it. Thank you. What part of MTC Service would be causing that? Cause on previous builds, The Safe Volume on boot worked fine.
[MTCB Android Head Units Q&A] etsmes:
Hi typos1,

Thanks a lot for your answer.

Just a few more questions:

Do you know if it is possible to develop and updated version of MCU frimware with Ford compatibility like the AN-21 U one?

You said maybe in the futur will be possible to connect android directly to our Convers+ display, because car data hardware support is under development. This connection have to be done by bluetooth OBD?

thanks a lot
[MTCB Android Head Units Q&A] jkchr1s:
You would only lose steering controls since you have factory sound. To get the PAC to work you have to cut out the small white connector that goes to the red canbus box and splice in the PAC. I asked my seller to send another harness with mine so it didn't have a million splices in it to use the correct provided canbus adapter.
[MTCB Android Head Units Q&A] typos1:
My car has CAN Bus but resistive SWC too, but both key wires need to be attached. I ve read in the thread a few times that some cars only need one of the key wires attached. Its down to the manufacturer of your unit not supplying correct instructions.

You could wire in an on/off switch, its been done before on those types of units.

Very strange, does everything still work ok, including the buttons ?

The pre-outs are 3V, at least on Klydes, they are. 3V is not quite enough for my OEM amp, it needs at least 4V. Youd have to use either something that increases the voltage of the pre-outs or a converter box that takes a speaker level signal and converts it to a line level signal. Your ll have to search the thread for how to connect a BT OBD, but it can be done, I cant help as I use USB to OBD. Try all the VW/Audi options in factory settings/CAN Bus and see if you can get the display you want on your MFD.

Which ones the official repository ?! :)

It would bother me too, cant understand why you didnt get a vehicle specific unit, but still, you can probably buy bezels specifically for your Mondeo that fit exactly in the opening in the dash, although you may have to cut down the inside a little to exactly fit around your HU.

Its more the app on Android that needs to be modified to work with your particular Ford. I said it MAY be possible to use some of what is being developed for AA vehicle connectivity in the future on these units, the key word here is "may".
[MTCB Android Head Units Q&A] tylerwatt12:
Everything works fine, I'm thinking different developers must be sharing the MCU source code and creating their own forks.
[MTCB Android Head Units Q&A] typos1:
Its probably just a name change. The devs are the same for all versions and the code for all MCUs is very, very similar.
[MTCB Android Head Units Q&A] etsmes:
Hi typos1,

Excuse me. I'm a little bit lost .

You said:

So, where the problem comes from (MCU or Android)? And how should it be solved?

thanks a lot for being so patient and understanding :)
[MTCB Android Head Units Q&A] typos1:
Play around in factory settings with the different CAN Bus types, if nothing works you cannot get what you want.

However at some point in the future the manufacturer MAY add support for your vehicle, or you could try getting the info via OBD (this may or may not work) or at some point in the future something MAY be able to be made to work using the AA vehicle connectivity being developed (I say may as this could possibly be closed source or may only work with AA). You could also hack the CAN lines, it has been done, although not with an Android head unit, with among other things an Arduino, Google it.

Radio stopped working after new ROM and MCU

Hi all,

I updated my EONON GA5150F last night (KLD) to Mayalsk's August rom (RK3188, 800x480), and the newest KLD MCU, and everything seems ok except the radio doesn't work at all

It doesn't even seem like it activates the tuner, as when i try to change stations, there is no audible change like you'd expect, just a completely consistent white line noise. The radio does not appear to do anything.

I tried reverting to a 2.12 MCU as someone in the MCU Compatibility list with similar hardware (but not identical, same manufacturer/KLD though) reported it working, but to no avail.

Does anyone know what's going on with this? I would think this is related to the MCU but I saw somewhere earlier in the thread that someone was having a radio tune issue with this ROM, could it be the ROM? Does anyone know what the stock version of the MCU is for this hardware?

Any ideas or suggestions would be very much appreciated. Thanks!
[MTCB Android Head Units Q&A] Malaysk:
It all depends on the new MCU, go to the factory settings (password 126) - the first tab from the top - put a type of radio - apply - exit - Reboot
[MTCB Android Head Units Q&A] DiGi91:
I have two harnesses (One with the canbus adapter and one without it) so that wouldn't be terrible I guess. The seller replied to me asking for photos. So I sent the photo of the adapter they sent and told them what I needed. I used one of your photos of the compass canbus adapter so I am hoping I can get this resolved quick and easy. Not sure if I want to get it installed the hacked up way for now by the shop or If I want to just wait.... This sucks =/

EDIT: I am assuming that the install is much easier and seamless with the correct canbus adapter?

Thanks for all the help man, I really appreciate it.
[MTCB Android Head Units Q&A] maynardflies:
The man himself!

I tried several of the Radio types, nothing changed, I will try the rest but is there anything else we can look into here? Is there any reason that a particular version of the MCU shouldn't work, is there a particular supported MCU, anything like that?
[MTCB Android Head Units Q&A] Malaysk:
Yes there is. You need to know necessarily what you stood native MCU ??? The numbers at the end of it is very important ... For example KLD - KLD1 - KLD2
[MTCB Android Head Units Q&A] maynardflies:
In a collosally stupid move, I didn't record my original MCU. Is there any way to find it? I think this is the original system

(I'm not allowed to post outside lins yet, but the Klyde KD-7212

and from the reseller

EONON GA5150F

I emailed the reseller asking for the info but maybe someone has some idea?

[MENTION=3590033]Malaysk[/MENTION] Thanks for your ROM.

Is there a way to put the volume for the stock music player to lowest by default. I did set to low in equalizer but i still need it to be lower. Reason is that the Igo Primo TTS navigation volume is very low and music player overrides it even at lowest equalizer setting. Tried changing in factory settings for sound and set system volume to 0 but that has reduced overall system volume including Igo Primo. I can achieve this by another player from android market using it's own equalizer but wanted to see if it can be done through stock player.
[MTCB Android Head Units Q&A] Malaysk:
Unfortunately it is impossible. :( On Poweramp this can be done without problems, the stock player - you can not

Malaysk, Thank you very your nice rom.

I just installed update_4_4_4_800X480_RK3066_25_MAL_NEXT_LAUNCHER_09_08_2015

I have some questions:

- the Shot Down button display only (reboot + recovery). There is NO (Power Off + Screen Record).

What am I missing? Whey I don't have Power Off and Screen Record under Shot Down button?

- I have a full back up with TWRP format. How can I get the apps only from the backup?

I want to restore IGO from the backup but there is no TWRP or CWM (ClockWorkMod) installed I think? (May be I missed understand this part :( )

How can I use the TWRP or CWM recovery?

Which one you are using in your ROM?

Thanks.

[MTCB Android Head Units Q&A] halloj:
In the case of JY it's easy to swap icons. What about KLD? Is there any easy way to swap icons on the main launcher.

I like to have Waze and other icons rather than the standard ones. If I move an icon it only leaves an empty space and

it's impossible the exchange icons.
[MTCB Android Head Units Q&A] agentdr8:
To change the main "nav bar" buttons in the KLD launcher, you have to hit the Car icon first, and then drag desired app icon to the space in the nav bar.
[MTCB Android Head Units Q&A] DiGiTY:
How do you stop app icons in the launcher from disappearing when they're updated via Google Play?

Anyone know if it's safe to install KGL versions on KGL HU? E.g kgl1 kgl2 etc
[MTCB Android Head Units Q&A] halloj:
I like the clean style of KLD. Next is too cluttered in my opinion. KLD shows the selected station on top of the

Thanks for the update. I will download poweramp. Reason to use stock player is that it's quick on start. Adding custom player to startup service takes at least a minute to start music. Of course i am using a different player not sure about how poweramp would work.

Again appreciate your hard work for this ROM. There are lot of people who loves your work. My NAV looks lively now.

[MTCB Android Head Units Q&A] slackmartian:
I too have radio issues on latest Malaysk. And I didn't update my MCU and previous Malaysk worked.
[MTCB Android Head Units Q&A] maynardflies:
So is your radio non-functional with the new ROM without updating the MCU? Maybe I'm barking up the wrong tree about the whole wrong MCU thing...

Is it the same symptoms? Absolutely no discernable tuner activity when trying to tune the radio, but everything else seems to work ok?

What HU do you have? Is it KLD based? 3188?

Malaysk, could you have a look at the ROM and see if something could be affecting this?
[MTCB Android Head Units Q&A] slackmartian:
Yes, no MCU updates only the rom and radio isn't silent it just isn't tuning anything. So just noise... Was working excellent on previous rom. KLD2 MCU and RK3188...
[MTCB Android Head Units Q&A] maynardflies:
Wait, you have a KLD2 MCU? What exactly is your headunit? I have an EONON GA5150F which I think maps to the KLD2112 as the same unit, but I flashed a KLD MCU and I'm wondering if that's wrong or not. My Radio is the same, just line noise, clearly nothing tuned

Maybe this is a ROM issue then? Have you tried flashing back to the previous ROM?
[MTCB Android Head Units Q&A] slackmartian:
HU is pumpkin brand. I pasted a link to it on one of my previous posts..

I have a GS unit and have tried various images and MCU's; I'm having the same problem, screen doesn't pickup my touches on the top 1cm or so of the screen (so the status bar, as well as the menu in "factory settings"). Mine actually stopped working all of a sudden without my making any changes to the firmware, I flashed and have done resets without any improvements. Did you ever figure out what caused this?

Corret root image for KDL 3188 800*480

Hi All,

After reading 1000 or so pages on Android head units, I think I have found the correct image to flash my unit with which has root built in, but I would just like to confirm.

My unit specs

Model Number: S07

MCU version: MTCB-KLD2-V2.51

Android Version: 4.4.4_15052015

Kernel Version: 3.0.36+ root@ubuntu #13

Build Number: rk3188-eng4.4.4 15052015

From the file mirror here:

http://huifei.fs-fileserver.de/content/firmware/KK 4.4.4 Quadcore/KLD 4.4.4/800x480/

I'm thinking that the KLD 800x480 20150715 Fake/ is the best image to flash to give me root access, can anyone please confirm?

Thanks in advance

Same here!!

I owne dual core on 4.4.4, button less screen, running under JY.

Since one month and without notice the top of the screen (about 1 cm under the statut bar) doesn't respond to my touch.

I try to flaxh new mcu and rom but nothing change. I open the screen to check if naps were well connected but all looks ok.

However i have noticed that when i let my car under the sun and the radio is geeting the heat, the screen respond a couple of time then nothing again.

since we are already 3 to have this issue, let's keep in touch when we find out something.

all advises are more than welcome

Hi just wanted to share some info, may be in the 1000 pages though.

Bad radio reception with pumpkin android stereo, after playing around with wiring and ending up buying a different antenna for my bmw x5 which was ok reception i had a bright idea that the original bmw antenna would be an amplified one that needs to power up. The stereo adapter wiring didn't use this it came with an antenna adapter booster and reception was very poor.

Solution. Cut the white wire (same for most bmw's) from the original bmw stereo harness and connect to the blue antenna wire on the new stereo loom, if it uses the antenna adaptor booster don't connect that blue wire to anything. This powers original bmw antenna amp and now i have better reception then the original stereo.

For any other make of car get a wiring diagram of stereo wiring and find the antenna amp power wiring and you should be in business.

Sorry if this has been posted but hoping to help someone as i have wasted so much time on this already

WiFi Issues on 1024x600 KGL RK3066

Is anyone else having periodic issues with WiFi on their 1024x600 RK3066 KGL unit? Most of the time the WiFi is fine, but periodically the follow happens:

WiFi signal fluctuates significantly from full strength to nothing, even when close to AP

Unable to ping device from network (can't access ADB because of this)

Takes very long to attach to WiFi AP

Device powers up with WiFi turned off. Cannot turn WiFi back on unless reset switch is pressed or power is completely disconnected

I've already modded the antennas on several which helped immensely, but we're still having these issues. If I could find the source for this, I'd patch the drivers to remove some garbage such as power save mode.

Hi Friend

Thanks for the support and information but still I haven't got through the issue.

I disconnected the internal mic, soldered the external mic wiring to 4th (Mic +) and 3rd (Mic -) still there is no voice in the BT nor in android (I didn't remove the C102 capacitor). I checked the mic if it is working on other device and it looks fine to me. I didn't get any voltage from the BT mic connection though. Any solution or is there anything specific to do with my version (KGL MAIN 90D V2) the BT does not depict the mic + and Mic - and through the forum I assume it is same BT module and PIN 3 and 4 will be for MIC

Please anyone has any update on this guide me.
