[MTCB Android Head Units Q&A] jrgalang:
Hey all, while trying to flash Malaysk' August ROM today the update prompt won't come up again. Currently on the July version of Malaysk ROM, RK3188 1024x600. Not the first time I encountered this, and I resolved it before by replacing the SD card to a smaller capacity (8GB -> 2GB). But now even with the 2GB card, the prompt won't come up. I checked MD5 of the downloaded update.img in both my card and my PC and they're a match this time so I'm not really sure what's going. Steps done so far:

1) Tried replacing recovery.img http://xdaforums.com/showpost.php?p=62067954&postcount=16577 (what's interesting is that the extracted recovery.img from the same ROM of Malaysk both from July and August ended up with just a black screen on my device... and I had to use the recovery.img found in the Google Drive repository instead)

2) Tried using another SD card

3) Checkdisk / reformat 2 cards so far

Any thoughts? If anyone has a TWRP flashable version / backup version of Malaysk' latest ROM, maybe I can try using that? The traditional method never seemed to play nice with my unit so far.

Screen Backlight

Hi Guys,

I have a question: I have HuiFei 4.2.2 MTU 2.01 and just one disaster. When I turned the lights on, the screen dimming, but just ~10%. So at night it is stil to bright. Is it possible to dimming the screen to 10%... A have rooted device. Also XMTC or other programs are not as good as They wrote, because when I turn lights on, off it's gonna to reset the backlights... :D

So do You have any idea, how to do the dimming by turning the lights more dark?

Thanks and question about the launcher...

First of all thank you for your hard work Malaysk. After replace the apks in the System/app they work great, but the Launcher don't work, actually the original in the folder System/Priv-app is Launcher2mtc2 so if I just put the new one in there (Launcher2mtc3) don't do anything, I try renaming the apk to Launcher2mtc2 and then replace the old one but that also didn't work. Any idea what I'm doing wrong?. I'm still a little inexperienced on this, I try to find the solution here in case someone have the same issue but with so many post is almost impossible, Thanks.

When i went from stock to custom my device also didnt notice the update. My workaround was go to settings about and update and then the device found the update. Maybe you can try that. I did this just to be sure without a internet connection.

Hi, I now have the same problem. The external AMP does not receive the remote turn on signal. Did you fix this by moving to an older MCU? If so which one?
[MTCB Android Head Units Q&A] vdubskey:
So ordered a 7" Hot Audio double din on eBay, had them upgrade the unit to the RK3188 16GB/1GB for only 20 bucks more which I thought was pretty cool.

Anyways in the storage section it is showing I have 1 NAND Flash, 2 Mountable SD CARDS, and 2 USB Storages. But this unit only has one visible SD slot. So I opened up the unit and found two connectors. One says NAVI SD CARD (Which is by the actual SD slot) then I found one that said MPEG SD CARD that is not being used from what I can tell. These connectors are the flat ribbon type.

With that being said, where can I find a compatible SD card terminal with matching ribbon cable? The original SD terminal is attached to a daughter board which is soldered to the LCD/Front panel controller and the same exact pins are on the other side with the MPEG SD connector.

I have pictures of the unit and the connectors at the following link on imgur:

[MTCB Android Head Units Q&A] PUFF1N:
So after flashing some different MCU's and ROM's it seams that the remote turn on trigger for an external amp is driven by the native radio and music apps. I need to start playing a song in the native music app which turns the external amp on, pause that song, then I can use any other player. Not really an acceptable work around, so I'll have to find a new remote turn on 12V from a different source unrelated to the head unit. However if the native apps also trigger the RCA out's to send music signal, then this won't work. Does anyone know if signal comes out of the RCA's regardless of the app used?

Quick root for 4.4.4 needed

Guys, first off - thank you for all your hard work on these images and roms - but can we please get a quick root method as suggested for the 4.2.2 method on the first page?

This would greatly help people who have other generic rk3188 units with 4.4.4 on them. I have successfully installed Malaysk's images on my device but had to revert back due to google apps crashing and other weird problems. When in fact the only thing that I was looking for is having root, which the image did provide.

It would also be nice to have a CWM image made that actually works :) :) CWM is out there for the rockchips so modding it to work right for these I wouldn't think would be too big of a hastle::

[MTCB Android Head Units Q&A] koimr:
For root, go to Settings->Factory Settings and when prompted for the password enter:

*#hct#root#

This will temporarily give you root, to make it permanent install either SuperUser or SuperSU from the Play Store. :)

[MTCB Android Head Units Q&A] koimr:
Hey [MENTION=1670895]tsman[/MENTION]!

There should be two power connections to the head unit - one is ACC and is only powered when your key is in ACC or running and another which has permanent power (regardless of key position).

Is it possible you have mixed these up? Having the head unit's permanent power connected to ACC would definitely cause complete power off like you are describing.

For the radio channel reset thing, check out XposedMTC by the famous [MENTION=434511]agentdr8[/MENTION]. :) It has an option to remember radio presets.

Unfortunately I don't know anything about the static problem. You can try selecting a different radio type in Factory Settings to see if that's causing it.

Key mappings - detailed help is kindly needed

Hello,

I read thru all related post here on XDA and also on the 4pda forum. But I am lost and kindly need your help in a very detailed way.

I have this (with original MCU and Android versions):

Model: ES9610DE

HuiFei/KGL (KGL)

Original MCU: MTCB-KGL-V2.06

Model: S07

Android v: 4.2.2_30102014

Kernel: 3.0.36+ toot@ubuntu #1055

Build: rk30sdk-eng.4.2.2 30102014.11:40

I upgraded the unit to:

MCU: MTCB-KGL5-V2.53

Android: update_4_4_4_800X480_RK3066_26_MAL_16_08_2015 (thanks, Malaysk :good:)

Mostly it works after the upgrade.

But the 8 keys on the unit's front panel are not correctly mapped now. See the image.

Only the GPS button (which is assigned anyhow in the Settings) is correct. The other 7 are wrongly mapped.

I created the "mtc-keys" folder and the "mtc-keys.ini" file as described in - my case - the "/mnt/internal_sd "folder. However I am not sure how the rows in the file should look.

I run the CarService_2.1.3.apk as recommended to log the current key mappings and got this:

Left top-down:

keycode = 73
keycode = 72
keycode = 31
keycode = 51

Right top-down:
keycode = 23
keycode = 52
keycode = 3
keycode = 13

Then I wrote the ini file like this:

action_57 = HOME
action_74 = SETTINGS
action_31 = BACK [I](note: I am not sure this is the correct code for the "return" action (same like the horizontal "U" return key on top left corner of the screen) [/I]
action_51 = GPS
action_3 = RADIO
action_42 = DVD
action_80 = PICKUP
action_70 = HANGUP

But this didn't work. Note: I have enabled the mtc-keys Xposed Module

I also found a recommendation to try all radio models in Factory settings > Radio models. (i.e the various TDA**** or TEF**** ones). No change at all.

I might be totally dumb but I can't figure out how to fix this.

My questions:

(1) Did I install the correct MCU? I found that this unit needs the KGL5 but not sure.

(2) Could someone send me the correct ini file or at least a single row so I figure out the proper syntax?

(3) And pls advise what is the correct code for the "return" or "back" Android action.

Thanks in advance for helping me!

So I went ahead a tried out Malayks Rk3188 1024x600 JY rom on my unit but decided I didn't like changes made to the UI so I went back to my stock rom, never touched the MCU, and now my unit has been turning off randomly. Just cuts out completely. I thought maybe the voltage wasn't right but my meter shows it at a constant 12v. I even tried 13v thinking it wasn't getting enough juice. But no effect. Sometimes it will turn off a couple times just booting up now. The unit is only 3 days old and wasn't doing this before trying the custom rom. and figured that was the only change in the setup and now this happens. Any advice? Do these units have any type of voltage sensing or thermal protection that might be getting triggered accidentally? I mean this is still on the bench at home so I know heat or current isn't the problem, maybe just software. Thanks.

For sure the guidelines are inside the camera itself. Impossible to turn them off, and if you bought a camera without guidelines you'll never see guidelines. I doubt if the reverse camera input can be relayed to an app which eventually can capture the input and put an overlay with guidelines above the footage, but I'm not a specialist ... and I've seen more miracles happen on this forum. :p

Someone on the AN21-U thread soldered an external mic to the wires on the internal mic (and removed it), pretty sure that they said there was a big improvement in quality, its worth searching that thread (or the AN21-U hardware hacks thread) if youre still disappointed with the mic quality.

You dont (and couldnt) have guidelines on your rear view mirror or your windscreen and TBH if someone absolutely NEEDS guidelines, then I m sorry, but I d question whether they should be driving. :) But as someone else has said, theyre a camera thing, not a headunit thing.
[MTCB Android Head Units Q&A] agentdr8:
I might be able to do something with MTCBackView to add guidelines. I'll have to see if my theory pans out.

If it's possible, the only issue I see is the inability to properly scale the lines, as all cameras are different.

EDIT: I guess this would only apply once the system is booted, and not if you reverse when it's starting. Hmm, guessing there'd be less use for that.

Plus maybe this info will help others avoid repeating my legwork. Er...fingerwork? lol :)

Option #1: Eonon gm5163. This one has

- best looking face (its made for my mazda 3)

- awesome screen mirroring and 8" display

- better support than the generic clones

- but the win ce6 and 800x480 screen is looking a tad outdated for $380 ...

http://www.eonon.com/Car-GPS/Specific-Car-GPS/Mazda/GM5163.html

#2 Xtrons: TD729A+A1 or Td730A $380

- android 4.0 ( with detachable tablet face!) or 4.1 with tilt screen

- better looking GUI (dual core ARM9)

- but same 800x480, no screen mirror, needs dash kit bezel, less support than eonon.

http://www.amazon.com/XTRONS-Androi...ie=UTF8&qid=1405636018&sr=1-1&keywords=td730a

#3 Ugode (which might be a huifei?) DG6068 for around $340

- great specs: android 4.2, 8" screen, 1024x600, dual core 1GHZ with optional mirror link, fits my mazda.

- but it's total generic china clone from alibaba. :/

http://ugode.en.alibaba.com/product..._600_WIFI_3G_Dual_Core_Bluetooth_and_GPS.html

and lastly...

#4 CA-FI 80100 $575

- android 4.1

- custom fit for my mazda 3

- 1024x600 AND 8" screen!

- dashlinq lets you screen mirror and control the HU with your device (and vice versa, I think)

- 16 band EQ! (the others only had 2 or 3 bands, but some can fix that with apps)

- seems to have the most solid rep of the china units.

http://store.ca-fi.com/index.php?route=product/product&path=133_139&product_id=308

There are like 3-5 others I am looking at which are very similar to these... but I am so sick of research, I am almost ready to just buy a 8" tablet and velcro it to my dash. lol

I ve seen that one before, its model name is "RM-MD11" suggesting RoadMaster and as you say the back looks like a RoadMaster, but the menus and Homescreen are the Klyde type, its a hybrid ! Lol

I m afraid absolutely none of those units are anything to do with the ones in this thread, the first is a Windows CE unit (possibly made by Klyde), then there are some Android 4 units with removable tablets, then some android 4.1 units, plus a 4.2 with a single core Telechips processor, but none are RK3066 dual core devices.

The B&M wont make a difference to the SWC - you have 8 SWC buttons with or without B&M, they wont be connected to the B&M if youre installing this unit so they make no difference, the only possible thing is that the "Windows" button wont do anything windows related, it will do whatever function you assign it.

my unit is (as expected), a klyde:

MCU-Version: MTCB-KLD-V1.86 (please correct it on the first post, where klyde devices are listed with version ...KLY...)

here is what I have found not properly working so far:

Stearing wheel control / can bus:

Volume turns up or down automatically without pressing any button. Something seemst o be wrong with the can bus?!

Radio App:

AF (Alternative Frequency) does not work. The radio does not change the frequency even if much stronger signal is available.

On one occasion I realized that only front right speakers where playing sound. All others were muted. Adjusting the equalizer did not help, only complete removal of power supply solved the problem!?

The cooling fan of the device is very loud.

Wifi does not work properly. I use my mobile phone as a hotspot (Samsung Galaxy S4). But the connection breaks after short period of time and can not be reestablished until the unit is rebooted.
