I really tried each Radio Typ of them and always made a restart. It didnt help nothing. With KLD2. 2.51 it worked. No idea...
[MTCB Android Head Units Q&A] george2350:
Other than the radio is everything else working fine? MP3 playback using the Music app?
[MTCB Android Head Units Q&A] MayfairDROID:
There is a KLD2-2.55 with Sleep and Music fix available now. I had a KLD2-2.51 and just updated to the KLD2-2.55 Sleep/Music and everything works well.

Post 14139

Look at the bottom, where it says Firmware. Pick the Processor type you have, and then select the rom for 800x480 you wish to flash. If you want sleep, you need to flash the appropriate MCU update as well.
[MTCB Android Head Units Q&A] kruuth:
I found it.

Is there a factory EONON rom? I can't find display mirroring anywhere except in that rom unless there's one here.
[MTCB Android Head Units Q&A] MayfairDROID:
EONON is a reseller. Your HU is made by whomever made your MCU file. Even still, all the Malaysk ROMs, unless notated, are based on the KLD ROMs. ROM is not as important, as they are all interchangable as long as you flash the one for your processor (dual or Quadcore) and screen resolution. The MCU IS VENDOR SPECIFIC though, so make sure you install the right one, or your unit may not work. You will have to reflash to get it working again.
[MTCB Android Head Units Q&A] Waldorfer:
By the way: The radio via FM still sounds like a good AM station. The sound is crap (reception is ok, but treble is absolutely weak). I think it's "normal" for an android radio. What about your head units?

When I flashed the new firmware the lights where also off. But when I turn on the headlights of the car the dash lights up as well as the head unit.
[MTCB Android Head Units Q&A] mike.s:
The tuner has nothing to do with Android. It's all on the MCU. The tuner app just tells the MCU what to do.
[MTCB Android Head Units Q&A] kruuth:
I figured. However it looks like only the factory one allows you to mirror your screen. That's what I'm trying to do.
[MTCB Android Head Units Q&A] Reptile-X:
Hi Jeroen, you got me thinking there and I went for a solution with success :)

First I was experimenting with cooling the backplate because of my blown out amplifier IC, but I was busy with another solution by using an external amplifier and that works now.

So today I took out the head unit and checked for best possible solution to cool the WIFI board and the RK chip, after installing a 40x40mm fan just next to the WIFI board solved the WIFI problem, I was able to download 6GB Europe Map from TomTom servers without any failure, it scared me around 56% download because download speed on the unit went to 0B/s, but after couple seconds it keep going with the percentage that moment I realized the whole 6GB was already downloaded and the maps where getting installed, so download finishes around 56%.

Anyways thanks for the tip :good: :D I didn’t expect WIFI chip getting hot, after reading your post I checked back my older photos and I saw brownish color on the WIFI board which indicates heat on the coating.

Anyways this is my fan install:

Front view with CD player installed before installing display and processor board:

Everything put back together:

And success with 6GB TomTom Europe Map

Both of those activities are located within com.dr8.xposedmtc (specifically com.dr8.xposedmtc/.activities.Music and com.dr8.xposedmtc/.activities.Radio). I'm not sure if mtc-keys can launch specific activities, or if it only can launch the default one specified within the manifest. If it's the latter, then the button would just launch XMTC preferences, which is the default activity.

Great job! I'm still busy designing a bracket to guide the airflow because the unit isn't a full 2 din high. And I have the bleutooth module located where you have positioned the fan. So more challenges for me to overcome. I will send some pictures.
[MTCB Android Head Units Q&A] Murdock80:
Gday guys

I threw out my old EwayGps unit and bought one of these models (KGL Rockchip 3066) to replace it- pretty happy with it so far, but I'm having two issues with it:

- I upgraded the unit from the stock 4.2 image to the Coudu 4.4.4 January image and the 2.47 MCU. Now I don't get any sound from the front speakers when using the Radio and CD player. Any advice here? Used to work fine with the stock setup.

- Is the unit supposed to actually turn itself off when holding the power button? All I get is the "Shutting Down" message when pressing the button, but as soon as I press it again, the device is back on instantly.

Pretty sure something similar might have been asked before but I couldn't find anything when browsing through the search.

Thanks!
[MTCB Android Head Units Q&A] kruuth:
Hi guys. I've finally got malaysk's rom going. It's great. However, I'm trying to connect my android phone via USB to use as a modem. Is there a way to do this with this unit?
[MTCB Android Head Units Q&A] agentdr8:
Try flashing the original MCU version that it came with. If it resolves the speaker issue, then you can probably leave the MCU alone, unless you're after a specific feature (sleep timer, modified EQ settings, canbus support, etc). There's really no reason to muck with the MCU unless you're having issues.

That's how my KGL unit works. Except it isn't really a power off, as much as it's a fake "sleep". The only way of doing a full power off is to take the key out and wait ~30 seconds.

[MTCB Android Head Units Q&A] MayfairDROID:
anyone know of a way for the system to hold off restarting apps after sleep until WiFi is established? I use SiriusXM app almost exclusively, but when the car starts, the unit restarts the app faster than it can establish WiFi causing issues with the app....

---------- Post added at 10:14 PM ---------- Previous post was at 10:06 PM ----------

Yes. And I upgraded the MCU to KLD2-2.55 sleep and Musik and everything works wonderfully. Sound quality is great now. Have a few things i dont like, such as the soft power button, and the fact that the unit starts apps faster than it can connect to WiFi after sleep, but other than that, its perfect now.
[MTCB Android Head Units Q&A] agentdr8:
It should be possible to nest the restart loop for SiriusXM in another loop that runs a ping to something and if it comes back good, then start, otherwise sleep, and repeat check.
[MTCB Android Head Units Q&A] MayfairDROID:
That would be brilliant..how would one do that lol...;)

Hi Reptile,

Great tutotrial on how to instal this.

Quick question, where did you connect the wiring from the fan to?

And what about the noise, are you using a low noise fan?

Thanks for the reply

[MTCB Android Head Units Q&A] edit:
Guys,

Is worth updating the MCU with one moded for better sound if I use Viper4Android? Is the difference noticeable?

Thank you
[MTCB Android Head Units Q&A] markcm:
Yes,

The MCU sound update is just as significant as Viper, if not more.
[MTCB Android Head Units Q&A] edit:
Yes I understand that the quality went up but are you able to hear it when using viper4android or is just more usable when using stock EQ (or no eq at all).

Feel free guys to share your impressions if you upgraded and you used Viper4Android previously ... I am trying to figure out if i should update to get better sound or keep the original MCU in place because the v4a does the same job just fine.

I am a little reluctant to upgrade because read that some of you ran into issues... some solvable some...maybe solvable?

[MTCB Android Head Units Q&A] DJCannonball:
i have tested A2DP on some other devices: Lenovo Yoga 13 (windows8) , an old blackberry and a Nokia Lumia 520

inside A2DP, there are 4 codecs that can be used:

SBC

MPEG-1,2 Audio

MPEG-2,4 AAC

ATRAC family

when pairing 2 bluetooth devices, there will be a negotiation which codec to use and what bitrate.

in combination with my KLD HU somehow it chooses to use the SBC codec to transfer the audio (worst choice).

i even popped in a certified bluesoleil usb-bluetooth radio and set the default factory bt radio to IVT, that didn't work either.

is there a way to get a grip on codec-selection in the bluetooth stack?

and maybe 'steel' the bluetooth Atp-X feature from another firmware (for example google nexus) ?

i know this isn't hardware related.

Hallo guys i've a Problem after updating my mcu. Everytime i push the gpsbutton my System restarts. What can i change in the factorysettings?
[MTCB Android Head Units Q&A] DJCannonball:
apparently you flashed the wrong type of MCU.

only use MCU images for your type headunit. if your HU is KLD, then only use KLD MCU images.

Careful with flashing wrong mcus you might brick your HU.

this info is also on the first page.

I'm a KYD(witson) user same with you and I am upgrade the modify MCU by darkleo yesterday had 1 issue .The wheel controller was useless ,head unit function button work normal . Check the factory setting are same with before .

I don't know why ? Or someone could help KYD user modify the 2.43MCU of sound quality config .:p

About the sound quality I down think that be improved very much .The viper4android is direct and obviously .So I will recover to original MCU 2.43 .:(
[MTCB Android Head Units Q&A] Reptile-X:
Hi Maverick,

Thanks for your compliment.

With the wire I had two options, one of them was soldering the wires directly to the connector inside head unit, just inside where the power connector sits, and the other option was to bring out the wires outside the unit and using connectors to power the fan with ACC +12V.

I went for second option, because of the very same reason you ask; the noise. If the FAN gets to loud for my liking I can disconnect it easily now.

I have used a normal FAN and I can hear it if the radio sound is off, I am thinking to get a R56 5Watt load resistor and hook it up with a hidden switch so I can switch between the resistor and directly to +12, this way I can choose between lower speed and full speed.

The head unit is out again, thanks to Jeroen. He saw my copper fiddly thing on my radio antenna connector and the radio receiver was broken in the pictures so I am going to fix that and maybe add the resistor with a switch.
[MTCB Android Head Units Q&A] edit:

rooting KGL 4.4.4 rk3188 HU

Hi All,

Just received my KGL 4.4.4 (0150601 1024x800) rk3188 (Quad core ) + MCU (v2.47) HU and i'd like to root the system,

I see in the first post that since the Root Master app is not compatible with 4.4.x then my only option is to flash pre-rooted firmware (or inject SuperUser app which is for experts) - However I have 2 major problem with this option:

- I'd like to do backup first to the firmware & MCU , is there a way to backup them without needing root ?

- I can't find a pre-rooted firmware for my unit at the repositories , is there somewhere else i can look ?

TIA!!!
[MTCB Android Head Units Q&A] edit:
1. You cannot backup without root

2. As long as you choose the right firmware (choosing the quad core and correct screen ress it should work)

Are you sure your screen resolution is 1024x800 ?
[MTCB Android Head Units Q&A] MayfairDROID:
There is no way to back up your factory system, however, you can download the same MCU you currently have from the repository. You need to go to settings, about device and look for the line that has MCU in it, then download that same file from the repository. If you can't find it, post your file name and we will direct you to it. As for the rom, any rom will work on any HU as long as you get one for the processor type and screen size of your unit. Rooted factory images are listed on the first page, or for nodded ones, look at the bottom of Mayalsk's posts.
[MTCB Android Head Units Q&A] mrbean2k:
OK so i have no choice and continue without backup , Regarding the resolution - I was mistaken it's 1024x600 of course .

MX MCU Part 3! mission accomplished....MTCB-MX-V2.55 found :)

Hi Guys,

I know i'm just the only one on this forum, but there are also a few other Russian guys who have a unit with MX firmware. The good news is i have the MTCB-MX-V2.55 MCU. And a new official MX firmware for W2-A6XXX units (for example Witson units).

Also the sleep mode works with the official firmware for i think about 10 minutes. Today i'm going to install Malaysk rom (June 7 2015 800x480).

[MENTION=3590033]Malaysk[/MENTION]: When i use your firmware my radio does not scan for radio channels automatically. Any idea? And if there's no solution for it, is it possible to grab the original radio app out of the original firmware and install it manually in your firmware? Or has it something to do with more than just the radioapp alone?

MicroController Unit, System On Module, and I believe JY is for Joying.

I think BT streaming in car audio is a rather niche capability. I've used it in the past, but the sound quality you get out of 320kbs mp3s is lightyears above BT audio, even at its highest bitrate. That said, the BT on these headunits is oddly implemented, and the Android side doesn't handle A2DP/AVRCP.

Seems to work fine for me. I have whatever the most recent version of TomTom USA is.
