Can you please provide the following information:
- What's the (exact) name of your TV app?
- Screenshot of the TV app when it performs station scan?
- Which TV box model is selected in the factory setting's option menu?
---------- Post added at 10:20 AM ---------- Previous post was at 10:14 AM ----------


Which remote did you expect to receive? For the DTV box? Apparently there is none shown and mentioned in the advertisement because the intended operation of the DTV box is via the HU's touch screen.

HI
Its digital TV application.

The TV is standard silver box listed here;
http://www.aliexpress.com/item/AiRo...Box-Tuners-for-Pure-Android-4/2033316321.html

It has DTV4 ticked on it.

When I go to advanced settings, following is selected.
TV_03 ISDB-T (infospace)

and I tried to select DTB, but then touch screen functions in TV application stopped worked. I reverted the settings back to above and touch screen functions are working again.

I do not have screen shoot of it scanning, but when it does, signal quality stays at 0% but progress bar moves.

I looked up the electret mic, and it appears that it should be powered via some resistor (its drain terminal).
Just wondering how is an external electret mic powered if connected directly to the mic input of the BT module. Or maybe the external mics are not of electret type? Specifically, a Parrot mic I had recently purchased.

The BT module powers the MIC input @ ~1.4V. All car mics are electret with internal impedance matching FET (including the parrot ones). The Android CODEC can also bias the MIC (it has a separate pin for that) but it was disabled in the build by not installing a jumper resistor from that pin to the MIC since they shorted the internal and external mics (very bad practice).

Hi, new to the forum and just purchased a KGL-7685HD and need a bit of help.
Connected the unit to my 2007 Audi TT all works but I have no sound (just a lot of noise).
The car has BOSE but i was under the impression that it should just work with the connectors supplied. Is there anything else i need to get this working with the BOSE amp. Thanks

I have a Mazda with bose and I needed to cut the supplied connector speaker wires and connect them to RCA head unit output. No more noise from the speakers :)

Interesting, just a minor point, but the frequency also matches the 3188 - thats 1.6 Ghz as well, albeit as you said quad core not dual core.

My Klyde has good radio reception in the rain, wonder why yours didnt ? Mind you the AM reception is not very good, but this is common for a lot of aftermarket and OEM radios nowadays. I think a booster would help, was it AM reception that you had a problem with ?

I'm pretty sure the radio reception is partly/mostly my car to blame. The VW dual fakra diversity antennas have a bad reputation with aftermarket stereos. I have tried FIVE different antenna adapters now, all with largely the same result. I have returned the Klyde and got a full refund due to the missing GPS atenna and remote control that was advertised as included. Back to the GS (running latest klyde software). Of note, I completely rewired the GS wiring harness and the audio popping issues I had are gone. The harness came wired with two different factory connectors so everything was split in a "Y". I removed the extra connector and rewired it all so nothing is split and it's much better.

I see now the RK3188 is also 1.6GHz. Looking at this listing, it lists the GPU as Mali-400MP4 @ 250MHz up to 400MHz. AFAIK, the Mali-400MP4 is correct for the RK3188, but the clock speed should be 533MHz up to 600MHz. The 250MHz clock speed matches the Mali-400 (Non-MP4) which goes with the RK3066. Based on that and the fact all the listings state "dual-core" I'm pretty certain these are all the same hardware... RK3066/Mali-400.

I've noticed that the unit doesn't always power up when I turn on the key. If I click the power button, everything comes back up, though, so it's not *that* big of a deal. I'd say it powers up on its own about 20% of the time, and usually only if it hasn't been powered off more than an hour or so.

Anyone else notice this?

I see, thanks.
But do you have a CANBUS adapter, or is it the orange "illumination" wire that triggers the change (is it connected or not)?
And, are they RGB LEDs, or of fixed color?
And, have you noticed the LED connector I mentioned a few posts earlier when you opened your unit? Was it used, or not?

No canbus, but orange wire is connected. My GS appears to have white and green leds, but no other colors. IIRC, the led connector was plugged in when I had it open.

Thanks for the information.
Asking for the type of the TV app, the screenshot/picture and the setting in the factory menu I just wanted to check that you use the DTV app (and not the A TV one) and the settings is correct - and it looks like as everything is ok. Thus I'm sorry that I don't have a guess for you what else to try but just claiming a replacement of the DTV box by your reseller.

I have the same HU and the same DTV box, but I even don't get the touchscreen working, so I even can't do a channel scan.

Change the settings for the box type in advance settings and try all types one by one.

When my settings were wrong, I could not use touch screen function,
As soon as I put it back to what vendor has done, touch screen started working.

PS: you will have to restart the unit after each change in the settings.

I just installed a gs 4.2 unit, does anyone have experience with it? I cannot get the RGB leds to change color, I try to make the red come on to match the rest of my interior lights and the blue led comes on. If i try green, blue or any mix, no leds come on.
Also, is there a work around for google play music? I pay for subscription and would like to stream radio but the stock app only allows music from sd. I could switch to spotify if all else fails.

Sorry, mixed up HU type - mine is Erisin 9401. I did already go through all settings - but I don't know whether I did a restart after each change. Thanks for the hint. I will do it once more again but this time with a restart of the HU after each settings change.

    Moderation Announcement (added by @dark alex)
    Hi together this is an important announcement!

    As you knew Mike an me we were talking about a dedicated section.
    This is now achieved and I am requested by him to sort things out from here.

    I will split out some Key knowledge posts, for example malaysks Firmware-Post, to new Threads in our subforums.

    Developers
    Please if you create new work open you own Thread in the new forums. If you already have posted here probably wait until I split your post out or write to me to ensure I will split you out if you think I missed you or you have a critical release.

    Questionning Users
    Please open your own thread for your questions in our new section. I can not split out every question from here. This thread will be left over for searching so please if you have current questions just ask in our new Q&A-Section.

    I will start splitting up this thread in about one hour.

    You can find the new section at the bottom of this link:
    http://xdaforums.com/android-auto

    Thank you!



    This is a new thread for this car dvd that was first reported on comment #2224 of the AN-21 U thread.

    Probably you are here because:

    • you want to root your unit. Only units with ROMs 4.2.2 can be rooted (see below how). The only way to have a rooted 4.4.x is installing a pre-rooted ROM (see below how)
    • you have a problem (no internet, no sound, buttons do not work, bad mic quality, rear camera image not showing, door opening not showing, etc.
    • you want to upgrade your unit to a newer software that has sleep mode, personalized music app, personalized functions, root, xposed, can remap buttons, etc.
    All this is covered in this post and most of the problems that you can have are summarized in this post too. Please read this first post before asking. And use the search function of the thread, before asking. Thanks.

    TRICKS THAT MIGHT SAVE 1000 QUESTIONS ON THE THREAD
    Read below and here for basic questions asked and answered 1000 times.

    How to root my unit. Only 4.2.2 can be rooted with an app (see below). To have rooted 4.4x you must install a pre-rooted ROM (see below)
    Get sound when in reverse (thanx to @Keylo Lo)
    here
    Engineering/Factory settings password "126" (thanx to @blankers)
    This allows you to change logo, sound volume, SWC codification, etc.
    Activate USB debugging --> Go to Factory Settings and enter password "adbon".
    System sound is low compared to Radio--> Go to Factory settings and change volume levels
    GPS button does not trigger GPS app You need to choose predefined GPS app, in Settings--> GPS

    Get Into Recovery
    1 Press reset button and power button together
    2 After about 5 secs release reset button, but keep pressing power button
    3 When booting screen appears release power button.
    4 It boots into recovery.
    --Update 1-- some units without front USB have a different procedure
    Firstly power on the unit and then long press the power button and then reset. Then the unit will get three rings and you loose your hand on the power button and short press the power button again. (thanx @netay)
    --Update 2-- some others have this procedure (thanx @R4D3N)
    1. Turn off the unit by holding 3-4 sec the power button.
    2. Hold the RESET button + POWER button for 5 sec
    3. Release the RESET button and keep pressing the POWER button for 2 sec
    4. Release the POWER button and wait. The Recovery menu appears.
    5. With the Volume knob you can move up/down and long press on Volume/Power button to select the option.

    Get Into Bootloader
    The process is basically the same, with the difference that you need to have the computer attached to the unit via the front miniUSB (if you do not have a front USB, you will have to ask your seller how to get into bootloader mode)

    1- boot the unit as usual.
    2- plug the front usb of the unit to your computer usb.
    3- Then, push the reset button and the power button at once and keep them pushed. The reset button is the tiny pin next to the mp3 sdcard. The power button is the volume knob. You will hear the power cut throught the speakers.
    4- Release reset button and keep power button pushed. Now the unit will reboot. You will see nothing, just a black screen. Do not release the power button yet. Your computer will detect a " new hardware", that is the RolckChip. When you hear the windows noise of new detected hardware, you can release power button. It will automatically install the drivers.
    ------------------------------------------------------------------------------------------------------------

    HOW TO UPGRADE YOUR SYSTEM
    BEFORE UPGRADING YOUR UNIT YOU MUST KNOW
    • MCU your unit, there are many (KGL, KGL1, KGL2, KGL3, KGL4, KGL5, KLD, KLD1, KLD2, JY, GS, KYD, MD, BN, HA, MX), If you install the wrong MCU, you will brick your unit.
      To know which one you have. Go to Settings -->About
      If still not clear, see: here or here.
      If you cannot find it here, it probably means that you are in the wrong thread.
    • Resolution of your unit. 800x480 or 1024x600. If you install the wrong ROM, you will brick your unit.
    • Chip of your unit RK3066 or RK3188. It does not really matter, ROMs and MCU are compatible between chips.
    IT IS ADVISABLE TO BACKUP YOUR SYSTEM BEFORE PLAYING WITH IT
    Upgrading is supposed to be a safe operation, but you never know what can happen. So, before updating make sure that:
    1- To backup of your system the easiest way is download nandroid root from google play, and do a nandroid backup with TWRP format). Save it in your external SD.
    2- make sure you can enter in bootloader mode (see below how to)
    3- it is recommended to backup your apps and data (use titanium from google play). The update will do a factory reset.​
    FOLLOW THIS TO UPGRADE YOUR ROM AND/OR MCU
    0- Do a back up (copy the files somewhere safe) of your internal SD card memory. It will be wiped during the process.

    1- Download the ROM (Resolution 1024x600 or 800x480) and MCU (KGL, KLD, JY, GS,RM, MX, BN, HA) for your unit.
    ROMs--> repository This will get you a file named update.img. There are different "flavors" of ROMs.
    Code:
    - [user=853627]@coudu[/user] (rooted, stock). Early v4.0 and v4.1 have some problems.
    - [user=3590033]@Malaysk[/user] (rooted, with very useful mods, some come with NEXT launcher)
    - [user=6041319]@dsa8310[/user] (rooted, almost stock)

    MCUs--> Latest MCUs by Malaysk are here . This will get you a file named mcu.img

    2- copy the update.img you have chosen to the root of your GPS card.

    3- copy the mcu.img for your specific unit to the root of your GPS card (if you do not want to update mcu.img, you can skip this step)

    4- insert back the GPS card to the unit. If no window pops up, reboot the unit. At boot, the presence of update.img will be detected and a pop up window will ask you whether you want to update your unit. It will automatically reboot into recovery mode and update your unit. Once done, remove update.img and mcu.img from the root of the gps card or you will be asked every boot for an update.

    5- In some Coudu´s (sd partition of 3Gb) and Malaysk´s ROMs versions, it is necessary to do a factory reset just after the first boot so that everything works properly.

    6- If you lost buttons or radio after the upgrade --> Go to Factory settings (password 126) and choose the proper canbus for your car and the radio chipset. You can change boot logo if you want.

    * If you get Google services error after upgrading to KitKat see this and this
    ------------------------------------------------------------------------------------------------------------------

    THINGS YOU MAY WONDER BEFORE BUYING A HEADUNIT
    Code:
    [B]- Boot Up:[/B]: time is around 30s. 
    [B]- GPS[/B]: GPS positions very fast. TomTom, Navigon, Sygic,  and regular off-line GPS work. Navigon and Sygic have some problems with some ROMs
    [B]- Stand by mode[/B]: Latest ROMs and MCU have the possibility of choosing stand by mode with various times chosen.
    [B]- Radio:[/B] radio stations are saved as frequencies
    [B]- Bluetooth contacts:[/B] contacts are saved on the device.
    - Works fine with Bose system (Audi)
    - Possible ground loop noise that needs some tricks to be removed (see section problems) 
    - Torque works and can run in parallel with A2DP
    - ELM327 works (might need special app like CarService in very weird cases)
    - Camera works (might be better to get the one with RK3188 chip)
    - There is no automatic brightness control because the unit does not have light sensor, but there are apps that can help
    - The touch screen is extremely responsive. It works as good as most phones.
    -------------------------------------------------------------------------------------------------------------------

    HOW TO ROOT AND INSTALL TWRP
    Instructions to get root (thanx to @webdude12)
    It only works for Android 4.2.2. If you want to root 4.4.x you need to take apart update.img and inject SuperUser app (this is only for experts as @coudu, @Malaysk, @dsa8310 ). The alternative is to install a 4.4.x pre-rooted image and you do not have to do anything else. See below in HOW TO UPGRADE YOUR UNIT section how to do it.

    If you want to root your 4.2.2, download Root Master 2.1.1 here
    Code:
    1- Install the APK.
    2- Make sure you are connected to WiFi and you have an internet connection.
    3- Open Root Master (do not upgrade to newer version unless you can read chinese, The newest version has different options, all in chinese. Version 2.1.1 just has a button that says "root".))
    4- Press root button
    5- Chinese characters will flash across the screen.
    6- A second popup box will appear, press the purple button.
    The app will automatically install SuperUser.
    This program connects to servers oversea sending hardware information. The downloads a script that will attempt to root the device. If the first script fails, it downloads additional ones. Future goal is monitor this communication with a data logger and find which script works, so that a unique program can be written to achieve root.​
    ------------------------------------------------------------------------------------------------------------------

    How to install TWRP recovery (thanx to Abdul_pt from Freaktab and 1-2-Hak and coudu)
    You do not really need to install TWRP unless you wanna mod the rom yourself, if you mod roms you will know that already.
    - a.t.m. you need a mouse to use TWRP because touch is not working yet
    - if you install TWRP, you will not be able to update the update.img and mcu.img the way it was explained above.

    If you still want to install TWRP:
    Android 4.2.2 800x480
    Download files here
    And follow the post by 1-2-Hak

    Android 4.4.2 800x480
    Follow this: this

    TWRP for 1024x600
    See this post
    ------------------------------------------------------------------------------------------------------------------
    TRICKS AND MODDED APPS THAT DO WONDERS
    • Install app without adb when regular install does not work
      Sometimes the app won't install normally and you need to sideload it.. This means that you need a computer and adb wifi. There is another way with which you won't need a computer. You just need to install a terminal emulator (you need root ).
      1- Download the terminal emulator app you prefer
      2- Download the app you want to install to /mnt/sdcard
      3- Open terminal emulator
      4- On the terminal navigate to /mnt/sdcard by typing
      Code:
      - cd /mnt/sdcard
      - su
      - pm install "NameOfTheApp".apk
      Done, you are app is now installed.

    • Modified Radio Apps
      To install radios you need to copy the app using ESExplorer or Root Explorer straight to /system/app in place of MTCRadio.apk
      Radio version 4.2.2 800x480
      Radio version 4.4.4 800x480

      Radio version 4.4.4 (Malaysk v1, aka alive)

      [*]Car Service. Allows to use SWC and buttons with 3rd party apps (Latest Malysk ROMs already include it).

    Good news!! Now I'm going to lay out all of the latest firmware on the server http://huifei.fs-fileserver.de/content/firmware/MALAYSK%20ROMS/

    Thank dark alex

    Good news for Sygic users :)

    I have found solution how to make Sygic to work on ours devices.
    It is wery easy and it finaly works for me, and I would like to share it with others. You can make it in two steps.
    First of all you have to install rooted ROM. I have install update_4_4_4_RK3066_1024X600_7_MAL_14_05_2015.rar
    You can find rooted rom for your device on this link https://drive.google.com/folderview?id=0BxmzvLRI7-eNeVA2SWkwM1pLZ28&usp=sharing#listv
    When you done you have to install Xposed IMEI Changer. You can find it at Google Play Store and start the app. Xposed Installer will prompt up and you have to give permissions to IMEI Changer and to install Framework if you did not already.
    Than yo have to open IMEI changer and copy IMEI code from your smartphone. (I have HTC M7 and IMEI code you can find in Settings-Info-Tlefon identity.
    After that you have to reboot device and open IMEI changer to see is it new IMEI applied.
    If it is, than you have to go to Google Play Store, install Sygic and download maps.
    Result you can see on attached image.

    I hope that it will work for others.

    NEW from 27 October, 2015
    Only for RK3066 800X480

    Most global firmware update from me, perhaps a few months to 800X480.
    Changes, updates, deletes, transfers, etc. lots of. I write about everything I will not. Here are just a couple:
    +++ Android part of 10 October.
    +++ New NEXT launcher - a slightly redesigned our radio me :)
    +++ The new boot logo (the very first - that appears when you download a few seconds)
    +++ Added gradient Status Bar (Settings - System)
    +++ A new panel ext. programs and recently run (Settings - System)
    +++ Added new tab in Preferences - Advanced Settings screen (think there will understand)
    +++ Fixed program MTCBlueTooth - incorrectly displays the number of the incoming call
    +++ Well, and so on. D.

    Firmware I have not done a simple upgrade - erased all the data. Make a backup of your applications (System Settings then do by hand - not to restore from backup !!!)
