Radio problem.....

Hi guys,

when the Radio is not working, follow these steps ->

1. go to settings

2. go to factory-settings

3. press 126, then ok

4. go to application-patch (or something like that - top left)

5. change the radio setting (try all of these, one of them should be work for you)

6. after you change thise setting, reboot the Radio

Report when it works......

I have a question about the weahter app ? The weather app dont find my GPS signal, and i cant type a city in the app.

Is there a fix for that bug ?

Thank you :)
[MTCB Android Head Units Q&A] tmiller101:
Is the app finding stations and/or locking on to known freqs?

If its not check your antenna connection. Also, under factory setting there are settings for the region, make sure you select the right region.

If it is locking on and you here no sound, might try deleteing the app in the system/apps folder and reinstall it. Maybe something glichy happened to the original file.
[MTCB Android Head Units Q&A] kob87:
in the factory settings is the right antenna connection selected and also the right Area/region Band. The app does not found known Radio freq Stations. Only Noise. Its a TDA7786 device. The next step is a totally reinstall from the radio app. I hope it works! Many Bro's from me have the same problem -.-

I reply soon.

I have the Eonon GA1312 ( GA1312 1-DIN Android 4.4.4 Quad-Core 7” Multimedia Car DVD GPS with Mutual Control MirrorLink ) but I am unable to get it in to recovery using any of the methods in OP. Has anyone found a method for this model?

EDIT-----------------

• Power the unit make sure you have the screen open.

• Press the reset button to power down the system but leave the screen open.

• Press and hold the reset button for about 3+ seconds, you should be able to see the screen go slightly darker.

• As soon as you release the reset button, press the power button and hold it for 5 seconds. (One-thousand-and-one, one- thousand-and-two, etc)

• Release the power button for 1 second then hold it in again for another 2 seconds.

• Release the power button and wait for the screen to attempt to close, before it completely closes- hit the open button to get it to stay open.

• You should see the system load into the recovery.

Hi all ,

I m not sure i overlooked if already asked/answered.

May i ask if someone can suggest a link for buying SoM 3188 board to swap my rk3066 ?

Kind regards

Also, partly I think it is reset successfully.

However, some of my later installed programs remains just still installed

Now the following problem: the "unknown sources" will be dimmed (gray)?

So I can only install programs of google play.

Does anyone know how I can reset it the "unknown sources" ?

Just a heads up, on the YINUO MCU's (I own a KGL3 v2.68) the Bluetooth works but you can't control it, and only way it works is if before flashing you pair your devices. By accident I unpaired my OBD-II and now I can't use TORQUE only answer my phone and listen/talk from the unit to the phone (hands free) the A2DP is not enabled because when switching to Bluetooth app it switches to hands free and you can't press the "MUSIC" button to enable A2DP. Not sure why, tried the Factory Settings, 126 pw, and changing it to all kinds of BT (it was set to SD_BT) tried IVT_BT, all of them, with no luck. Worse case, can't I just plug in a USB BT dongle?

EDIT:

Another thing I noticed is, if I change it to non-24hour i.e. 1pm instead of 13 it doesn't stick, and reverts back to 24hour format. Besides those 2, this rom ROCKS!!!! I installed all the apps I use and MORE. :)

I installed the latest Malaysk ROM (12/25/2015) and everything is now working perfect. I highly recommend his ROM! VERY VERY GOOD!!! ALL WORKING!

Make sure you use RIGHT MCU!!! IMPORTANT!!!! If not sure, ASK MALAYSK if you can keep your old MCU and only use UPDATE.IMG and test.
[MTCB Android Head Units Q&A] florin1up:
The cars that are using CAN interface cannot use the remap buttons function (is written somewhere on their website). I have reverse-engineering and found that in order to use the remapping function, must be a hardware modification. But you cannot have both things (info on MFD and programable buttons), and you will need another canbus decoder.

There are 2 points on the mboard where you can connect a resistive remote control. Example: 1kohm resistor from pin 1 to gnd can be programmed as volume down or pause or whatever. 5 kohm resistor can be programmed as another function and so far.. I want to build now a custom programable jog dial. The sad thing is that you cannot control other apps like poweramp

If you want to invert the next/prev buttons, you must go to factory settings menu and type 126 as password and there search for "swap canbus next prev" option.

Working android apps using canbus informations

Hi! Is there any working app that support CANBUS and can read any informations from ECU like oil temp, boost, volt etc? Im searching it for my Seat Leon 1P 2007. Something like PolarFIS for big FIS LCD on the dashboard but when I have android HU I thought, there can be something for it. I have pre-installed app named Car Information, but there are only few not very important informations like how fast I drive and how much fuel I have. I'm searching for some better apps, especially boost and oil temperature are very important for me. Thanks for some tips.

Blank screen help!

After a bit of help. I have a Klyde unit with android 4.4.4 on it.

800x600

RK3066

Ram: 1GB

CPU: armv7 1.6GHz (x2)

MCU: MTCB-KLD2-V2.50

6 months old

I put the Malaysk firmware on it 6 months ago and did the external microphone fix and have had no issues with either.

The issue is That the blacklight is coming on, but the screen is just black. Have tried resetting the unit, leaving it unplugged for a few days and checking the ribbon cables are seated correctly. Nothing has helped and I have re-seated the cables, but to no avail. I did connected a screen to the rear video outputs and put a dvd in, this gave a picture on the external screen.

Everything is working as I can press where the presets would be for the radio and the station will change. I can also, from memory load up poweramp and get it to play music. So the touch screen is working fine.

No idea what has caused this as the screen hasn't been hit. I drove for 4 hours one night with it working perfect, then the next day the screen was just black as soon as I turned it on.

I am assuming the display has broken somehow, just wanted to see if anyone else had any other idea as to the cause of my blank screen?

Hi guys,

I "installed" this Launcher on my Radio (Radio Firmware: Malaysk - 4.4.4 - RK3188 - 800x480 - 19.10.2015)

But the Launcher UI is very small and I cant add shortcuts on the bottom (like the picture)

What I did wrong here :/

Thx

From within the bluetooth app select the sync icon. You will get a notification on your phone that your radio is accessing you contacts. I have found the sync function to be unreliable and sometimes it pulls the data across in varying formats. So if it fails... try and try again.

Every time you sync it wipes all previous info.

Hi everyone. I have just upgraded my HU to the Malaysk firmware (from 11 December, 2015, for RK3188 800X480). This is an Eonon unit with MCU MTCB-ZD-V2.81 and I did not try to upgrade or touch the MCU. Unfortunately now my radio doesn't work. I'm trying to use FM and I'm getting sound on one frequency, all other frequencies are mostly static. The factory setting is set to the Europe band. Before the Malaysk firmware the radio was working fine. Everything else works fine.

The unit is an Eonon (GA5153F).

Any help is appreciated, or anything I can try. Thank you!

Kinda unrelated question. Tried to wire a auot-vox rearview camera today. RCA cable in the deck. Red wire powered with the reverse light and black wire grounded (12v and ground was properly working).

Nothing happened? Anyone know what else I have to do or what I did wrong?

EDIT: Never mind. I got a reply from the seller. I didn't attach the reverse light in wire on the deck to the red power wire. Well I think thats what he meant.

[MTCB Android Head Units Q&A] m4f1050:
Why don't you use OBD-II instead of CANBUS? I use an OBD-II Bluetooth adapter on my VW cc. Torque has an option to start in dashboard mode, which can show you (I have done up to 12) but you don't need that many and my radio is 1024x600 so not sure if you have an 800x480 which has less room (or not less room, less resolution, so I wouldn't try to use 12 gaugues)

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

I believe (I don't have the radio so not sure) but you have to use the RESET button, check the FAQ to see if that radio's instructions are on the FAQ.

Thanks Brendo, but I mentioned it's set correctly to the Europe band, as it was before the firmware upgrade. Also I am in Europe, so it is correct.

I'm now thinking the antenna cable might have dislodged, which would be a huge coincidence so I'm thinking of checking that soon.

hi everyone.

i wonder if anyone can help on the following.

According to the manufacturer (of an android car dvd 4.4) directions i bought a HUAWEI E1820 usb modem. I plug it in and works just fine but only with the SIM card i used in it for the first time. After a month of use mobile data was over and i tried a second sim from the same operator. The first sim is prepaid and the second is a contract. I assume that since both sims are of the same operator (vodafone) apn settings should be the same. However i never set up anything. From the very begginng prepaid sim and usb dongle were brand new and i just plug them and played.

The seconnd sim works with the dongle but it does not connect to 3G so there is no connection to inetrnet. Android car-dvd recognises the usb dongle with the second sim, it shows signal strength but not the 3G symbol.

Any clue?
[MTCB Android Head Units Q&A] SeBsZ:
Yes you need to set correct apn settings, probably inside Android. These settings differ between prepaid and contract.

Hi,

I had the same Radio like you.

You don't need to install the Firmware in the recovery-mode, you can install the Firmware in the settings -> about Tablet -> Software-Update -> then press install (here you can chose, delete all Data or not).

But attention with this Radio, because you need a MCU for this Radio to get it worked.

The problem is, the MCU from this Radio is not 100% compatible to these Firmwares here (do you have the MCU: *****alex***** ?)

I tried to install only the Firmware without the MCU, the install was successful and it works very good.

But i'v got 2 problems -> first: when you plug a USB-Stick or SD-Card the system does not recognize it

second: the password for the factory reset does not work (126)

When you have some questions about the Radio, ask me :)

Now put the update.img in a usb-stick and insert the stick in the unit.

Now go to recovery and press the reset button short to move.

Then move to the option update wia usb-stick (update + delete all data) and hold the reset button to choose this option.

When this works its god, but when the unit cant find a usb-stick, follow this steps below:

+ Put the update.img into a sd-card

+ open the unit (replace the screws of the unit)

+ insert the sd-card directly on the motherboard of the unit

+ go to recovery

+ move with short press on the reset button

+ move to update system with sd-card, then hold the reset button to choose this option

Pumpkin button illumination color

Hi,

I've recently updated my head-unit (Pumpkin KD-C0223 - Dual core Android 4.4) to Malaysk's KLD2 rom from 02nd Dec 2015 and updated my firmware to KLD2 2.55 MCU (factory version).

I was initially having problems getting my external amp to power on and the factory MCU fixed this problem. However, I'm left with one annoying issue.

The buttons on the unit are blue and I need to change them to red to match the color of the other car illuminations. However, I cannot find anywhere to change the colour in this rom (I can only turn them off on the 126 factory menus).

Is there an APK I can install to change the colors?

I would be massively grateful for any help anyone can offer with this!
