It sounds like the auto dimming for night time is working and you have the setting set to 0% light. I would go through the settings and make them no less than 50% as well as go through the MTC settings and car service settings. I say go through these one by one because something is only doing it sometimes per what you said.

USB sound option

Hi,

First of all many thanks for you all the guys who contributed enormously to this forum. I actually ask a question a week ago and no one answer to it. However, many of you thought that there is an answer around the forum. Anyway it is not a a big problem. I have some more questions; The first thing is I have a different HU and its running win CE. In that device i am able to adjust subwoofer frequency and also the low cut point of the all other channels. However, in my RK3066 4.4.4 1024*600 device we are all unable to adjust its level and for sure the cutting frequency. This made me to do some research and come with a basic answer, that android is not too good at multi channel sound processing. It is normally able to send two stereo channel information via USB. Then i seek for DAC options which can process the sound and create nice multi channel amps. In windows based system one can easily attach an USB sound card then can obtain very nice sound via that card, for eg. CM6206/8/9 option. So, is there any USB sound processor that you now supporting android? Because i am more interested with the sound quality in my car and willing to build a multi channel Class-D powered amp. If someone knows then just put the name of that IC. The other thing is there anyone that can open the SW settings which is already inside these android devices? There may be some other options for eg. HDMI output which is not available in our device but, i think it is actually inside the device.

Best wishes to all

I was looking for an easy way to root my 4.4.2 head unit, and I found one that works. Kingo Root 2.5 APK available on the mobilism market.

It took about 5 or 6 tries for it to work, but it successfully rooted the system, and it seems to be running fine.

Initially it was getting hung up at 40%, but after retrying as the program said to do a few times, it finally completed the rooting process.

Here is a link to the webpage

I just used the SYNC app on the head unit, i did opt for the extra CAN interface that was an option when buying the unit.

Your car did have Bluetooth before changing to the new head-unit?

As far as i can tell the SYNC app is an interface with the original Ford equipment, the layout is different but not to bad..

What happens when you press the SYNC app?
[MTCB Android Head Units Q&A] BiliTheAxe:
No, it turns out that my system is like these units, but not one of them.

There are subtle differences, so things like the root pass don't work, also I do not have a GPS sd card, sygic is installed in the main memory instead.

Also the pass for entering the engineering section does not work.

Anyone know where I can get a Dodge boot animation from? Mine does not have that either, and I want it. I've tried making one before, but failed miserably.

I have a HotAudio unit, brand new.

On my desk, running off a power supply, it draws 250mA when off. This will kill a car battery in about a week. I know it's not in sleep- in sleep it draws 600mA, and then 30 seconds after it goes to sleep it drops. When I boot it from the 250mA state I get a cold boot.

Is this normal or do I have a broken unit?

Backup camera

Hello,

I have a question about wire connection for a backup camera. I have a JY HU and camera on a ford focus (no canbus). I am not sure of where to connect one wire (see the picture).

Thank you for your help.
[MTCB Android Head Units Q&A] halloj:
That cable is used to carry +12 volt from your white back-up light to detect that you're in reverse. Should be connected to the reverse-cable in

your HU-loom. I.e if you don't have another way under the dash to detect reverse.
[MTCB Android Head Units Q&A] jordanow:
Thank you for your answer.

So basically 2 cables should be connected to the 12v of the white back-up light (one for powering the camera and the other one for detecting I´m in reverse.
[MTCB Android Head Units Q&A] halloj:
Correct.
[MTCB Android Head Units Q&A] warr4768:
Nothing happens,I did have Bluetooth but I assumed when you take the original head unit out you take the original Ford Bluetooth out. I still have ford audio paired on my phone, I tried to pair to see if the Bluetooth is anywhere else but nothing happened. Reference to the canbus I only connected the ford harness to it, I did not see any other spare wires left. It would be good if I could have my original sync back.

Hey guys, so I recently bought a headunit for my slk280 2006 from aliexpress. It didn't turn out to be the one as advertised but it is the rk3066 and I seem to like it, the problem is my MCU is MTCB-HLA which I have not seen any sort of firmware for. Is it safe to use JY or any other MCU to update it?
[MTCB Android Head Units Q&A] OneCheekyDevil:
Dont go mixing up MCU firmware or you'll risk bricking the HU.

I'm guessing you need the HA firmware, but i'll let DSA or MALAYSK step in and confirm.
[MTCB Android Head Units Q&A] antvic:
Well, I'm back to follow your step by step instructions; but TomTom still settling into the internal memory. I already do not know what to do. Good, Yes; can't find a solution I not renovaré subscription with TomTom, I will continue with Sygic that Yes allows me to place all maps in external memory.

About "command df" I must say that I do not know what means.

I do not think that it is so difficult to resolve this matter. I've done other things more difficult.

I would remind you that I have the latest ROM from Malaysk to 3066, I don't know if it will be relevant.

Anyway, if I can't find a solution soon, I will forget the theme and TomTom. I sent them an email telling them the problem and does not seem to import them much.

You said, " at THIS POINT there is a boot up delay before music starts and high amp draw on standby". Is it safe to assume after a period of time developing the ROM and kernel that these two issues can be fixed?

I have a 2008 Ford Edge that we spent ~$2,500 for a sync nav unit upgrade that I've been beyond disappointed with. I was thinking about upgrading to one of these units.

One thing I will say is the stock radio with Premium subwoofer sounds pretty good in the car and I'd like to keep that same quality sound. How would you owners compare the audio quality between and OEM HU (with sub) and this one?

Which reseller/model would you guys suggest as far as upgrade ability and reliability?

The current Version is mtc-keys-2.4.

Since Version 2.0 action, activity, intent are also supported.

Because i haven't seen some example about the configuration, i will poste my actual configuration with the Version 2.4, and it works fine!:good::good:

First i've tried the Version 2.1. This won't work under Android 4.4 (its stop the start with an error)

You will find the current version under ..sorry not allowed for me to post the link .... , but you have to register to download files (it's very hard to register in russian :)).

app_42=com.microntek.music

action_4=apps

activity_44=com.android.settings/com.android.settings.MtcAmpSetup

That means:

- With the "DVD" Button (42) the MediaPlayer starts instead

- With the "MUTE" Button (4) i will get the overiew of the current running apps

- With the "LOUD" Button (44) the equalizer will start instead the Loudness toogle

What happens when you start the SYNC app on the head unit?
[MTCB Android Head Units Q&A] greatmilk:
So my rk3066 1024 unit has a horrible touchscreen issue that started right after installation on my first drive with it. There is a dead zone that runs horizontally across the head unit so I cant even click on things like "ok" in a confirmation or use the top part of the keyboard. I've tried many things including resets, replugging everything in (including all the cables behind the touchscreen) and messing around with the factory settings. The manual says to recalibrate the touchscreen in case of problems, but I do not see any way to do so. Can someone offer some tips of how to recalibrate the screen and hopefully that will fix it or do I have a defective unit?

[MTCB Android Head Units Q&A] agentdr8:
Maybe, but it's probably easier if you just download a newer GS mcu from the FTP server. Details are on the OP and Wiki.
[MTCB Android Head Units Q&A] torquemonster:
The latest GS MCU I can find anywhere is 2.54, while my unit had 2.73. If I can get 2.73 off my backup, I can post it for everyone else...

---------- Post added at 03:54 PM ---------- Previous post was at 03:49 PM ----------

And I guess along with that...

GS MCU's are listed as HotAudio, however when I put a HotAudio MCU on my machine, the buttons were wrong and the MCU was listed as a "HA" MCU. Also, HotAudio's web site doesn't show my unit. Is GS actually a different vendor?
[MTCB Android Head Units Q&A] vdubskey:
All of the MCUs that I downloaded for my HotAudio unit given to me straight from HotAudio all have the HA tag in the MCU. Never seen a GS.
[MTCB Android Head Units Q&A] mike.s:
There's no known way to backup an MCU image. It's totally separate from Android. TWRP backs up Android partitions/files, the MCU image won't be in the backup.
[MTCB Android Head Units Q&A] torquemonster:
Thanks. That's what I assumed and was afraid of.

So does anyone know who makes the units with "GS" as the MCU identifier? It doesn't appear to be HotAudio like the OP wiki says.
[MTCB Android Head Units Q&A] agentdr8:
I too have a GS unit, but no idea who makes/resells it. After buying, the seller on AliExpress no longer responded to any of my inquiries (typical).

I just wait and eventually a new GS mcu shows up, and if I'm lucky, darkleo modifies it to improve sound.

What's wrong with the v2.55? It has the sleep timer, and you can get the improved sound version too.
[MTCB Android Head Units Q&A] torquemonster:
Well, when I put 2.55 on my unit, it boots with no backlight until I tap the mute button (center of volume knob). So I'd have to press that every time I get in the car. Appears newer hardware needs a newer MCU. It didn't do this with 2.73 on it, and it doesn't do it with other MCU vendors on it either (the buttons are just messed up).

Also, my unit is drawing 250mA when turned off. Still drawing 250mA 15 hours later. Which will kill my car battery in a week. Not sure if this is a MCU issue or a bad unit.

pls take my appologies for any misspelling, but english is not my mother tongue. maybe that is also the reason why i cant find the right keywords in search to find a solution for my problem.

i have a rk3066 with 1.6 ghz dual core mcu=klyde rooted and running with mcu mtcb-kld-v2.55. Antenna-booster, desk-camera, navigation, alsmost everything is running quite good, but i have one issue that drives me nuts.

its the music-player starts after boot-issue. i bought the poweramp full version wchich replaced the factory music playing app - but now poweramp is starting automaticaly. if you are hearing radio an switching of the unit, after restart the radio is playing and poweramp at the same time, after every boot i will have to close the music app manualy.

i tried to fix this problem wit the free version of the app "autorun manager" but it didnt solve.

how can i preven t the unit from autostarting poweramp and any other music player or radio? is there a fix?

and is there a way to force "wlan on" after booting the device?

Hello, friends.

I have a KGL RK3066 unit, now with Android 4.4.4 and last Malaysk firmware version. But I realized this problem just after upgrading from original Andrond 4 version:

If I begin to watch a DVD right after using the RADIO, there is a kind of interference noise, mixed with DVD sound.

If I turn on the unit and play DVD (without use Radio before), the sound is perfect.

So, the issue is related to Radio.

I've tested the same situation on another unit, so the problem is not related to HW, is SW.

Anyone had this problem? How could I solve this?

Thanx a lot.

Paulo
[MTCB Android Head Units Q&A] DJCannonball:
It depends on a lot of things, like

Quality of cables

Quality of amps

Chipsets inside your headunit

I spent a quite a few bucks on these and still i have a (barely audible) tiny hiss and a high pitched sound.

The pitch hight changes when i step on the gas or step on the brakes

It has probably something to do with the hybrid system ( i drive a prius).

My car has 9 300v batteries and a 13v auxiliary battery that feed my amps.

I have tried a groundloop isolator between HU and amps. It takes away the tiny noise, but it also takes down a lot of soundquality, lows and highs.

My Hu came with a dual-core cpu rk3066, and i changed it with a quad-core rk3188 SuM. It doesn't change anything on soundquality. The only disadvantage with Kld units specific with 1024x600 screens: the graphics are slight garbled if you put in a rk3188 SuM.

Kldunits with lower resolution screens don't have this problem, neither do have the other brands.

[MENTION=4071425]torquemonster[/MENTION]--If your unit is still on your bench, you probably have not disconnected the ACC connection to the head unit because it will continue to

about 6mA! You have a problem if it still draws 250mA after removing that wire.
