This is a new thread for this car dvd that was first reported on comment #2224 of the AN-21 U thread (http://forum.xda-developers.com/show...28349&page=223).
HOW TO KNOW WHAT UNIT I HAVESPECIFICATIONS SUMMARYThere are 5 types with similar features:to find which unit you have:
- HuiFei/KGL (KGL)
- Klyde (KLD)
- RoadMaster (RM)
- GS (GS)
- JY (JY)
- MD (Rhythm Audio) (MD)
- check the MCU that is installed on your unit. Go to Settings -->About
- if still not clear, see: http://forum.xda-developers.com/show...postcount=1669
UNITS HAVE TWO SOFTWARE PARTS:- All the units have the same chip, RK3066, and use the same apps, but have different hardware.
- MCU (These are incompatible between units, you have to use your own type) --> mcu.img
- ANDROID (These are compatible between units, you can use whatever android firmware coming from any unit, KLD, KGL, JY, ... etc) --> update.img
OTHER FEATURESCode:CPU: RK3066 1.6GHz Cortex A9 Dual-core [COLOR="red"] GPU: Mali-400MP4 Quad-core GPU, @250MHz up to 400MHz Storage memory: Samsung DDR3 1GB Wifi adaptor of type IEEE802.11B/g/n compatible WLAN - OS: Android 4.2.2 - HD: 1080P - Nand(flash): 8G - Storage memory: DDR3 1GB - Multipoint Capacitive screen - Support original steering wheel control to work with the car DVD player - 34 different car logo to match different brand of car. - Support 3G module - Built-in Wifi
VIDEO REVIEWCode:- Boot Up:: time is around 30s. (from @blankers video review). No stand-by mode (only for 30s, then shuts down). Resumes last operation. - GPS: TomTom is working - Radio: radio stations are saved as frequencies (update: last system update or radio app storenames), not names. Names are shown when listening, though. - Bluetooth contacts: contacts are saved on the device. - Navigon does not work properly. Sygic works flawlessly. TomTom works flawlessly. - Works fine with Bose system (Audi) - Possible ground loop noise that needs some tricks to be removed @webdude12) Needs this -->http://www.amazon.com/gp/product/B00...&tag=chryou-20 - Torque woks via bluetooth and it can be run in parallel with A2DP --> Bluetooth adapter is probably multichannel. - Display is crisp and clean (no problem to see it at daylight at 75%). There is a brightness control in settings, but no automatic setting. - The touch screen is extremely responsive. It works as good as my Evo 4G LTE.
You can find a review here. The quality is bad, and the comments are on chinese, but the images are still there.Hui Fei TRICKS YOU NEED TO KNOW
Another review here (thanks to @blankers):
First units are arriving and first videos from owners are coming up (by @blankers)
Part 1: http://www.youtube.com/watch?v=0GFcKTNUkM0
Part 2: http://www.youtube.com/watch?v=SMYQgJZ7GBo
And, another review ( by @webdude12 )
Get sound when in reverse (thanx to @Keylo Lo)BEFORE UPGRADING YOUR UNIT
Engineering/Factory settings password (thanx to @blankers)
This allows you to change logo, sound volume, SWC codification, etc.
Password in the settings menu is "126"
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-- 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 butoon 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.
Upgrading is supposed to be a safe operation, but you never know what can happen. So, before updating make sure that:HOW TO UPGRADE YOUR SYSTEM
1- you have a backup of your system (the easiest way is download nandroid root from google play, and do a nandroid backup with TWRP format)
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.
0- Do a back up of your internal SD card memory. It will be wiped during the process.HOW TO ROOT AND INSTALL TWRP
1- Find out which model of unit you have (KGL/KLD/RM/GS/JY) see here
2- Download filesThere are 2 kinds of files inside the tar files.
- update.img is the android firmware
- mcu.img is the mcu update (more info here)
2.1- Go to repository or here and download the MCU (mcu.img) of your specific unit, if you have a Klyde take a KLD mcu.img, if you have KGL, take a KGL mcu.img. To check car-mcu compatibility see here3- Download any Android part you like (update.img), KGL/KLD/GS/RM/JY they are interchangeable (see Custom Firmwares section below). Latest version is Coudu's 4.4.4 v4.2 (based on KLD), see here , or see Malaysk's roms w/ and w/o NEXT launcher, also 4.4.4 here, latest JY version is this one
(* sometimes the mcu.img is a single file, sometimes it is found in the whole package under a .zip/.tar file. You have to unzip and copy mcu.img)MTCB-KGL1 --> This is the mcu for BMW and Mercedes
MTCB-KGL --> This is the mcu for the other car makers
- From v1.86 settings menu includes bluetooth menu and fixes wifi issues for some people.
- From v1.99 some people have 2-way canbus (only VW).
- From 2.09 some CANBUS functions have been fixed
- Coudu v4.0 and v4.1 have some problems. v4.2 is good (based on releases 141223 for KLD and 141210 for KGL4- 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)
- TomTom does not work in Malayks ROMs. the rest is great (based on releases 141223)
5- copy the update.img you have chosen to the root of your GPS card.
6- insert back the GPScard 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.
7-(ONLY FOR KITKAT with 3Gb of internal SDcard). At first the internal SDcard partition is not recognised by the system, you have to erase/format it. To do so:7.1- Go to Settings-->Storage and erase the internal SDcard.8- Congratulations, you are updated!
9- go to Factory settings (password is 126) to change boot logo if you want. Choose car and DVD to have the logo of the car.
* If you get Google services error after upgrading to KitKat see this and this
Instructions to get root (thanx to @webdude12)Modded Apps
It only works for Android 4.2.2
Download Root Master 2.1.1 http://forum.xda-developers.com/show...postcount=4595
1- Install the APK.The app will automatically install SuperUser.
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.
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 probably not be able to update the update.img and mcu.img the way it was explained above.
If you still want to install TWRP:
Download files here

Install app without adb when regular install does not workFILE REPOSITORY
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 preferDone, you are app is now installed.
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

Custom KitKat 4.4.2 by 4pad.ru http://forum.xda-developers.com/show...postcount=5046
Latest version is Coudu's 4.4.4 v4.2 (based on KLD), see here- Coudu v4.0 and v4.1 have some problems. v4.2 is good (based on releases 141223 for KLD and 141210 for KGLMalaysk's roms w/ and w/o NEXT launcher, also 4.4.4 here- TomTom does not work in Malayks ROMs. the rest is great (based on releases 141223)Latest JY version is this one
Unfortunately the first issues with the promising unit arrived.
- @webdude12 got a black screen while driving due to a broken clip (see attachment to figure out which one). One solution is to glue the clip so that it does not get loose. Not doing that can end up in major problems.
- Unit might not boot on very hot conditions as it has a thermostate to avoid possible problems. It will work normally when cooled down.
- Some apps do not show completely in the screen due to the low resolution. However, there's a great solutions for that:
- you need root- install xposed framework (google it)
- probably you need to sideload the apk with ADB as the unit refuses to install it normally.
- install "app settings" module in xposed framework (you can change dpi for individual apps and make them fit in the screen)
- When add a google account, it doesn't show under accounts
fix --> http://forum.xda-developers.com/show...postcount=1303
- Wifi or buttons do not work after update to 1.86 or 1.99 firmware versions
- This happens because the MCU or kernel of the new version is not adequate for your unit. Luckily MCUs and kernels are mixable for the same unit.
- It looks like the best combination is:
- Firmware v1.99/v2.02
- MCU v1.86
- Kernel 1.77
fix --> Install 1.99 firmware with 1.86 MCU normally. Then install kernel of 1.77
To install kernel v1.77 --> http://forum.xda-developers.com/show...postcount=2784 and files needed http://forum.xda-developers.com/show...postcount=2787
Kernel install for doomies (with pics): http://forum.xda-developers.com/show...postcount=2804
- No radio reception
fix --> your ground cable might be loose Sold it back. see http://forum.xda-developers.com/show...postcount=3258 and http://forum.xda-developers.com/show...postcount=3266
- SD card unexpectedly removed // USB unexpectedly removed
fix --> Thanx to @ R4D3N http://forum.xda-developers.com/show...postcount=3258
- MIc sound is awful

and --> http://forum.xda-developers.com/show...postcount=4925
- Wrong door being shown open. Only VW and KitKat 4.4.2
fix --> Go to factory settings, change "Rude"
- TomTom not working on KK 4.4.*
fix --> http://forum.xda-developers.com/show...postcount=5336
alternative fix --> use foldermount to mount /mnt/internal_sd/Android/data/com.tomtom.* to wherever you have your com.tomtom.* folder with maps (WARNING: with foldermount, the folder of the maps is mounted a bit "late" and it could be that tomtom cannot find the maps if it is started earlier. I recommend using the first fix, i.e. dsa8310 method)
