Hi

Do you now be any chance how to put this unit in recovery mode using reset button or others buttons on the radio

Did you check the easy connected app by me It don't work
[MTCB Android Head Units Q&A] bricomann:
HI,

I have not found yet and I have not managed to connect it to a PC. Is made by Luyuan and must function as wd8801 .Can be that someone has more info on the wd8801 model ... have one inew u3 phone and mirror link is fully functionnal , on the phone you must turn on the USB debugging .
[MTCB Android Head Units Q&A] 1birbmanq:
I also just purchased this and installed it (via ebay)

Boot time is right at 30 seconds.

Backup cam works even before it boots so it works as needed.

Pandora works

Wifi connects to my phone hotspot for data

Radio works

I was able to remove that glowing circle (setting)

Changed boot image to my car logo in password protected area

Allow music in reverse

Installed google maps and changed settings for the GPS button to load goggle maps by default

Phone can make and receive calls via bluetooth

Can't get to work:

Android screen mirroring

bluetooth data sharing

bluetooth for torque app

I was able to get the obdII adapter to pair, but the app keeps trying to turn on bluetooth when it's already on.

I'm planning to get:

USB front camera

3G dongle

Overall very good value. Missing some features of more expensive units, but for the money ($103.49 after $20 off ebay coupon) this can't be beat! Shipped via FedEx so arrived in about a week.

Thanks for the videos you posted.

If anyone can get more use from bluetooth than just the phone, please share. I've looked through hidden menus and tried a bunch of apps with no success.
[MTCB Android Head Units Q&A] bricomann:
How did you manage to pair OBD. me only the phone connects, Are you sure it was the OBD who was paired? and not your phone?

Mirror link is functional but you have to activate the option for develeppeur and usb debugging.

look this video for mirror link https://www.youtube.com/watch?v=BLN_yXqqAjM
[MTCB Android Head Units Q&A] 1birbmanq:
To get OBD to pair:

Download shortcut manager lite

hXXps://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite

Then click 3 dots on right

Search for "bluetooth"

The first link there should be to pair. Click on it, and then click the run (rocket ship). It pairs, but that's it. I can't get Torque or any other bluetooth to "turn on" other than the phone call app and BT audio.

Did you use a USB front camera or another type? I haven't purchased that yet or a 3G dongle.
[MTCB Android Head Units Q&A] bricomann:
For dvr cam I have that http://www.ebay.fr/itm/262141040813?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT could be better but enough for me , for forward looking I have that http://eu.banggood.com/Wholesale-Wa...a-HD-Night-Vision-CCD-Camera-wp-Eu-90974.html but I find it very wrong and inverted image , I will change .
[MTCB Android Head Units Q&A] 1birbmanq:
Thanks for the links. I was thinking it needed to be a USB camera.

I was able to get mirroring to work on the second try. Not sure why it didn't work the first time.

What was the "free gift" that came in the second package? Mine is expected on Saturday. I'm assuming it's an SD card with map software, but that is just a random guess. If so, what maps? Software? Up to date?

If anyone had a bluetooth USB dongle, could you try putting that in the front USB and see if you can connect that to an OBD or data connection from your phone?

I can't put my hands on one right now.
[MTCB Android Head Units Q&A] bricomann:
Mine is came with nothing , gps software installed is igo primo but without maps or sd card , had tested 4 bluetooth dongles , but whitout sofwares for control these dongles , give nothing .
[MTCB Android Head Units Q&A] 1birbmanq:
My free gift that I mentioned was junk. Went straight to the trashcan.

Thanks for posting bt adapter results, now I won't bother to find mine.

[MTCB Android Head Units Q&A] grogan197:
Kingoroot was the only app I found that would root it for me. Tried a couple of versions of kingroot and towelroot with no success.

What sat nav apps have people managed to install? I've got igo working after downloading some maps but many of the popular ones say they are not supported on the play store. I tried market helper to see if I could change the device model for the play store but it throws up a token not found error.
[MTCB Android Head Units Q&A] dtrain123:
If you go into Settings -> System Settings -> Setup Setting -> Enter the password "66668888"

There is a setting called "Reversing Mirror mode" I think that should mirror the reverse camera. (I haven't tested it myself though).

Hi my unit is working fine but there is just problem with Itube, when I play youtube video for first time it works but then when I want to play it again the screen is green.
[MTCB Android Head Units Q&A] caralvie:
Two doubts.

- Are there any way to switch off screen for save energy?

- I tried to import car logo but system always answer doesn't find any file to import on usb. I tried with .jpg and .bmp inserted on USB and microSD. Any idea?

Thanks
[MTCB Android Head Units Q&A] MoshPuiu:
1. Yes! You can turn off screen by swipe down the notification bar and there is an icon like a display where you can turn off display. Radio or music will play in background. I don't know an automatic way of this.

2. For those who do not know:

- 'large lamp' is related to dimming display/screen when you turn on the headlights or parking lights. It will dimm or not the brightness...

- 'electronic dog' is related to limit amount of data use on mobile networks.
[MTCB Android Head Units Q&A] caralvie:
Thanks. I checked some days ago an icon as you said, but I thought it was for camera connection (but I don't have) I'm still testing with external battery.

[MTCB Android Head Units Q&A] robimo:
Hi at all :)

I've seen the version with android 5.1 and I'm interested to buy this radio.

Can someone confirm the depth is 14 cm ?

How is the quality of the reception in FM radio ?

thanking in advance.

robimo
[MTCB Android Head Units Q&A] tspoon765:
I have the 4.4 version. If the new version has the same electronics, then the FM radio quality will be quite good. It is easily better than the JVC headunit I replaced. In my car the aerial is in the back, my old headunit experienced poor reception due to the aerial cable length. The new headunit does not suffer this problem, and the sound seems to be good quality, not suffering so much from the overly compressed sound that FM can be prone to.

Volume and settings

If there is a saved settings file, you can download it (luyuan_system_configs).

If the file is not saved you can try the file of other users. There is a 4pd site. 11 page (unfortunately I do not yet have the right to insert links) You need to consider that this file is another user and it's its settings. He likes it so much.

Awesome thank you (and thanks you MoshPuiu for uploading it)! What do i do with the file though? :confused:
[MTCB Android Head Units Q&A] xm32:
It is necessary to put in root microSD and to put in a radio tape recorder. Slot is experienced. (I do not know)

P.S. Just received from my Chinese the introspection that you need on usb
[MTCB Android Head Units Q&A] chanchanman:
I had a look around and found the file in the '/system/etc/' however upon inspection, my configuration appears to be the same apart from one line which is missing: ' <FlashlightSetting setting="2" time="0" color="0" />'

I don't think this is related but will give it a try and replace my file anyway!
[MTCB Android Head Units Q&A] MoshPuiu:
You can do nothing unless you are rooted... Then you can copy and overwrite the default file located in system/etc/ folder. Here I can't help you because I didn't root my device.

Did anybody install any car launcher with good results? And weld an antenna for wifi?

Actually i found there is an import function at the bottom of the 'setup menu' where you enter 66668888 as the passcode...it imports the 'luyuan_system_configuration.xml' file but you need to rename it to 'luyuan_system_configs' and it only imports via USB. Anyway, that hasn't made my volume know jump back into life so maybe my knob is simply broken :D? I will keep living without it until i find out otherwise. Thanks for your help!

External Microphone

I connected a microphone from and old Nokia hands free kit to the two pins on the back of the stereo. (see picture) It has improved the quality of the audio when using Bluetooth phone calls. The stereo is designed for left hand drive cars, with the mic being on the left of the stereo, my car is right hand drive, so people found it hard to hear me while I was on a call.

[MTCB Android Head Units Q&A] Habieru:
Not like that one, but the receiver seems to be exacly the same. Anyways, it doesnt matter wich PC remote you use as long as it has the generic multimedia keys for play/pause next/previous etc... You just copy those keys from the PC remote to the steering wheel remote and thats it.
[MTCB Android Head Units Q&A] caralvie:
Thanks for answer. I tried but nothing. I went to steering wheel buttons and it doesn't detect the remote control buttons. Besides, navi detects it like a keyboard and doesn't show touch keyboard.

I have a bluetooth pad but I can't connect it because Navi must links it searching from bluetooth screen (and it hasn't)
[MTCB Android Head Units Q&A] Habieru:
If you slide down the notification bar, tap on the input method notification and you disable the "use hardware keyboard" switch the on screen keyboard will show up again. Also, you dont have to map the buttons there, you have to use any other 3rd party music player to ge the multimedia keys to work. The built in music player is terrible.
[MTCB Android Head Units Q&A] caralvie:
Perfect !! Thanks a lot !!

---------- Post added at 07:06 PM ---------- Previous post was at 07:02 PM ----------

Well.

About some doubts I wrote several are solved:

- I installed "Car launcher" and it looks better than original with red buttons.

- I tried succesfully to import new starting logo.

Now I'm trying to remove the "Warning Don't watch video when driving"
[MTCB Android Head Units Q&A] dtrain123:
I've found this image file in the /system/media/bootanimation.zip file.

You should be able to modify the bootanimation.zip to display whatever you want it to.

See this guide: http://www.addictivetips.com/mobile/how-to-change-customize-create-android-boot-animation-guide/

You just have to make sure you only use 1024x600 images.

Access to the /system folder will require root access.

---------- Post added at 03:23 AM ---------- Previous post was at 02:54 AM ----------

On further reading it should be possible to copy a bootanimation.zip file to the /data/local/ directory without having root access.

I'll probably have an attempt at installing one tonight when I get home.

I found some car themed boot animations here: https://xdaforums.com/android-auto/mtcb-software-development/mod-boot-animation-toyota-t3351617
[MTCB Android Head Units Q&A] chanchanman:
Nice, glad to hear someone has tried this as i also wanted to try! Just out of curiosity, what did you use to connect the bare wire to the pin, as i know its quite tight in that connector space along with the other pins at the back?
[MTCB Android Head Units Q&A] gmcmen:
I used the front panel connectors to motherboard from an old PC, you should find plenty in your local dump!

[MTCB Android Head Units Q&A] caralvie:
- About rear cameras ... I saw several navis show a distorted image. I suppose video is 4: 3 format and screen is 16:10 (approx). Most cameras are 756x720 and I suppose image will appear distorted. I found some 656x492 too (less definition but I hope it will not appear distorted) I don't know if PAL/NTSC is an important. characteristic

- Yesterday before instal "car launcher" I achieved power off navi pushing button some seconds, but now I can't (showing classic "powering off..."). Any idea?
[MTCB Android Head Units Q&A] yakaja:
mismo problema!

No logre que el GPS funcione, lo hice root con kingroot y me borro muchas aplicaciones, lo reinicie de fabrica y no pasaba del logo, trate de instalarle un firmware desde la SD del GPS y ahora ni siquiera aparece el logo, ya me di por vencido, si alguien encuentra la manera de revivirlo que lo cuente por favor. Gracias!
[MTCB Android Head Units Q&A] caralvie:
Thank you. As I see some users have problems after root, I will try the second option. I tried to rename original "bootanimation.zip" but I couldn't (probably because is not rooted)
[MTCB Android Head Units Q&A] dtrain123:
I did manage to upload a new bootanimation.zip file and finally got rid of the "Warning don't watch video when driving!" message.

/data/local requires root access so you can't upload the file there - the internet lied to me.

So I ended up putting the file in /system/media/bootanimation.zip and it works from there.

I have the 5.1 Android version (build: LG_EN_RK_LY503_HV_1701091213_MV4.4B022_503_7786r_1612231033) and couldn't find anyway to get root using Kingroot, Kingo Root, Framaroot or Towelroot. None of those programs worked.

However I used adb to connect to the device and opened adb shell

The adb shell automatically has root permissions so once you connect you can do what you want from there.

Once you log out of the adb shell you loose the root access so I don't think it does any harm to the radio.

I used the Nissan boot animation from here: https://xdaforums.com/android-auto/mtcb-software-development/mod-boot-animation-toyota-t3351617

This is the result: https://www.youtube.com/watch?v=3HOx-MgeMpo

The first image is the standard boot logo that you set in the settings menu.

The second moving animation is my modified bootanimation.zip
[MTCB Android Head Units Q&A] JVASQZ:
Hello, Did you had some result with the option without root access?

Thank.
[MTCB Android Head Units Q&A] caralvie:
Thank you for answer.

I don't understand "I used adb to connect to the device and opened adb shell"

I'm noob. :D
[MTCB Android Head Units Q&A] dtrain123:
ADB (Android Debug Bridge) is a Google application that lets you connect from a computer to an Android device and install apps, debug apps, copy files and control the phone. The "adb shell" command lets you remotely open a linux shell and run linux commands on the android device. For the RK-A701 radio the linux shell runs as a root user, so has permission to copy files to the /system directory.

The procedure I used was a bit complicated. When I get home tonight I'll try and streamline it and write some step by step instructions.
[MTCB Android Head Units Q&A] caralvie:
Yesterday afternoon I was watching videos of it, using commands to copy files from PC to android and form android to PC (push and pull commands if I remmeber...).

I worked with ubuntu years ago (and MS-DOS "long time ago") so use command line is and old friend :D:D:D

A video copying "bootanimation.zip" to "./system/media/"? was a good help (for QUILPUE, me and others will have this problem) I hope ALL click "Thanks!" besides use it :p
[MTCB Android Head Units Q&A] dtrain123:
Changing Boot Animation

So here are the steps to change the boot animation:

1) Make sure both the computer and radio are connected to the same WiFi network so they can talk to each other.

On your computer:

2) Download the Adb program onto your computer. It is in the SDK Platform Tools here: https://developer.android.com/studio/releases/platform-tools.html

3) Extract the platform tools to C:\adb\

4) Download a suitable bootanimation.zip file and copy it to the C:\adb\ folder.

You can get some car themed animations from here: https://xdaforums.com/android-auto/mtcb-software-development/mod-boot-animation-toyota-t3351617

On your radio:

4) Download and install the Developer Options app by uDroid from the Playstore: https://play.google.com/store/apps/details?id=net.selfip.unet.developer_options&hl=en

5) Run the Developer Options app and turn on USB Debugging

6) Find out the IP address of the radio. Go to Settings, long press on WiFi, then press on the Access Point name and it will display the IP address.

The IP address of my radio is 192.168.43.134

On your computer:

7) Open a command prompt. Click on the Windows Button then type "cmd"

8) Type the following.

(Change the IP address from 192.168.43.134 to your radios IP address)

The /system partition is read only by default. So we need to remount it as read/write before we can make any changes.

Make a backup of the existing bootanimation.zip file:

Exit the adb shell and use adb push to copy the bootanimation.zip from your computer to the radio:

Check the file owner and permission settings:

You can see that the permission and user settings are different between the old file and the new one so change the new file to match the old one:

The permission settings and owner now matches the old file.

Now you can restart the radio and check to see if it works!
[MTCB Android Head Units Q&A] caralvie:
Fantastic work.

Thanks !!

I will try it................ (some hours later) It works!! but I see animation slow, "small jumps" :( I wrote in the other post to search a solution ;)

Next things to check is connect an OBD2 device. As it's impossible by bluetooth I will check with cables (USB-ELM327 & USB-KKL). If this option don't work... only OBD2 wifi will be the solution
[MTCB Android Head Units Q&A] caralvie:
With other navis can be used USB-OBD2.

[YOUTUBE]https://www.youtube.com/watch?v=WE_EgH4jHj8[/YOUTUBE]

I hope it works with our device. It is better solution than BT device because it drains battery .. but it is necessary to check with navi off keeps usb supply or not.
[MTCB Android Head Units Q&A] dtrain123:
I had a look at the alfa romero animation and it runs at 8 fps.

The desc.txt file inside the bootanimation.zip is:

1024 600 8

p 1 0 part0

p 0 0 part1

You could maybe change the 8 to a higher value. It would make the entire animation run faster, but might make it look a bit smoother.

I don't know how fast the RK-A701 is capable of going. The Nissan animation I used runs at 10 fps and looks a little bit jumpy.

I think if you could create a new animation from scratch with 15 fps I think it would look a lot better. Maybe even 30 fps would be possible?
[MTCB Android Head Units Q&A] dtrain123:
I made a 30 frames per second version of the Alpha Romero bootanimation:

https://www.dropbox.com/s/8zpsn4kby3iebd4/bootanimation_alfa.zip?dl=0

I tried it out on my radio and it runs much smoother.
[MTCB Android Head Units Q&A] caralvie:
I will try it. I suppose it has better quality because bootanimation I have is 3.68 mb and this 48.4 mb XD (more images and png instead of jpg)

I'll record a video before & after. Do you record videos?
