No worries.

First, I don't blame you in any way, I was the one who choose to deal with these ribbons.

Then, I don't think it make it worse since I came from a foggy grey to a reactive white.

I feel this more like "close but not enought"...

I'll try to reseat them.

Thanks a lot for your support.
[MTCB Android Head Units Q&A] uros86:
Hello, 2 questions.

1.My unit works fine. I need to turn it off and on manually by holding volume circle button. My question is this. Is it enough to turn unit off this way, because when I hit it back it takes me straight to home screen (no boiting up and boot animation) . Is my unit turned off this way at all?

2. Second, what do I need to connect to make my steering wheel controls to work. I have fiat bravo 2007 ?

thank you
[MTCB Android Head Units Q&A] gmcmen:
You need to connect pins 15, 16 and 17 of the radio to your car

look at post #187 for picture

I have attached a diagram for your car, I can't read it but there are pictures, if they help.
[MTCB Android Head Units Q&A] uros86:
thank you. as i can see, these wires are under the steering wheel.does that mean that i have to make wires from radio longer, because they cant reach under the steering ?
[MTCB Android Head Units Q&A] mydroidfren:
Installed this unit very nice device but here's the take:

1. Says 5.1 but when you tap build it shows K logo (Kitkat)

2. Bluetooth can't connect Torque & ELM OBDII (everyone face this )

3. Internal storage partitioned to 1GB with 700MB free space not enough for many apps.

4. Balance 11GB free space partition only some apps able to install but I found Sygic Maps to be able to install in the 11GB space hence it frees up 300MB in the Internal storage.

Anyone managed to figure out how to make apps recognize the balance free 11GB space without root please update there thanks!

Currently able:

1. Sygic Maps (best navigation app for this unit)

2. Es File Explorer

Second, there is no way to change launcher ? Can anybody help with this.????

I managed to get root access with latest kingroot but it cause instability.

Thank you

Stuck in boot animation

Help! Im new to this so I'm not sure if I'm suppose to start a new thread or continue off of this one. I bought one of these head units and everything was going well. KINGROOT was able to give me root access. I went ahead and changed the boot animation and now I'm stuck. My unit will turn on and cycle through the boot animation loop a couple times. Then it'll turn off and repeat. What do I do!? One comment said to unplug the unit for 24 hours then plug it back in. That didn't work for me. Please. Any suggestions would help.
[MTCB Android Head Units Q&A] caralvie:
Perhaps your problem is the bootanimation you changed. Read all post and you will find the solution.

Yeah it def is. I'll be combing through this thread. Thanks friend.

Anyone try this on an android 4.4 head unit? Read this is for android 5.1.

Our units are "fake" Android 5.1. If you touch it you will be the 4.4 animation (kitkat)
[MTCB Android Head Units Q&A] Mycarprojectz:
Okay... Maybe I'm just too much of a noob but what am I missing? I formatted a 2gb thumb drive (not easy to get one now-a-days) to FAT, copied the files from the firmware zip to the thumb drive, plugged it into the head unit and turned the car on. The boot logo comes on and the thumb drive flashes for three seconds and stops. Then the scene goes to the boot animation and gets stuck in a loop. I've hit the reset button, same thing. I then repeated these step after formatting the thumb drive to FAT32. No luck.

When I'm copying the files from my PC to the thumb drive, the thumb drive is flashing the whole time. But it isn't flashing for longer than 3 seconds when it's inserted in the head unit meaning no files are being copied. Is the thumb drive too big? Do I need a 1GB drive? What can I do? I can't get adb access as I don't have the ip address. I'm open to any and all suggestions. I'm about to just smash this thing with a baseball bat.
[MTCB Android Head Units Q&A] gmcmen:
Here is a video of someone doing it.

https://www.youtube.com/watch?v=kzvHcbvez2A

if that doesn't help

If you can log into your Router 192.168.1.1 something like that, you will be able to find the ip address of the radio, it would be easier to turn off all other wifi devices first.

My one shows up like in the picture, by clicking on it I see the ip address, yours probably wont be the same but you will be able to find it somewhere in the router settings
[MTCB Android Head Units Q&A] Mycarprojectz:
Yeah I've seen that video and been trying to mimic what he did. The thing is my thumb drive doesn't flash like his, so I don't think the files are being copied over to the head unit. The thumb drive continuously flashes when i'm moving files from my computer to the thumb drive but does not flash when the thumb drive is connecting to the head unit. It flashes for 3 seconds and thats it. I've tried this method with my drive formatted in both FAT and FAT32, with both a 2GB and 1GB drive, and waiting longer at each of his steps so that the files can copy over. Nothing.

Here's a video of me following along with that video.

https://www.youtube.com/watch?v=nKGiGX72jXA﻿

I can't get adb access because I can't connect to the head unit and I can't connect to the head unit because the head unit won't connect to my wifi connection. WHAT DO I DO NOW!? so frustrating. Any help would be much appreciated.
[MTCB Android Head Units Q&A] MoshPuiu:
I saw the video. It seems you didn't prepare USB drive in the right way. It seems the radio unit checks USB and didn't find update system file(s).

So, I think you should try to prepare USB drive more carefully because the radio unit did not give any warning message about that. I don't know the structure of update package but I think it is better to format the drive FAT32 to can read files above 2GB. Any modern android device should read any FAT32 drive (at least below 8GB or 16GB).

Maybe you can post the way or the structure of files on USB drive you tried to flash.
[MTCB Android Head Units Q&A] Mycarprojectz:
Thanks for the reply. What do you mean by prepare the USB? Is there more to the preparation than just formatting the USB to FAT32 and unzipping the firmware files to the usb? I attached a screen shot of the files (how the appears on the USB). Firmware link: https://yadi.sk/d/SU0N6FrD3HHoie
[MTCB Android Head Units Q&A] MoshPuiu:
It looks OK...

Maybe you should delete the .txt file...

Also you can try to change the label of USB drive, I don't know...
[MTCB Android Head Units Q&A] gmcmen:
I have just now downloaded the firmware from the link in your post,

I formatted a 1GB USB drive to fat32,

extracted the files and copied to to the root of USB

I removed both sd cards from the stereo, inserted the USB, turned on the ignition,

I did not do anything else, no reset or disconnecting power,

after the boot animation, I got a message to update firmware, I said yes and its done.

USB details and file structure used is attached.
[MTCB Android Head Units Q&A] Mycarprojectz:
What the duce? I'll try it again. My unit is stuck in a boot animation loop, could that be the reason why it's not working for mer? The guy in the video didn't have the loop problem either.

I don't get the 'system volume information" file when I open the firmware zip file. weird.
[MTCB Android Head Units Q&A] gmcmen:
Sorry you will only see "system volume information" if your computer is set to "show hidden files and folders"

I don't have the stuck animation loop, so I don't know the answer

anybody know where to find the maps that fit the gps?
[MTCB Android Head Units Q&A] OriginalGriff:
Wondering that myself...

You have to open the app, and download them from in that, it seems - but the app wants the SD card with the maps on installed first in order to run... :sigh:

I'm talking to the people I bought mine from, and they are "talking to their engineer" so hopefully it won't be long. In the meantime, have you considered loading a different package? I tried Here We Go (which is brilliant on my phone) but it fails to find the GPS, and am trialing OSM And at the moment - it works, and pretty well but I can;t get it to show speed limits or give speeding warnings, which it should be capable of.

Give it a try in the meantime - it's working in my car!
[MTCB Android Head Units Q&A] MoshPuiu:
You should try iGo NextGen. It fits perfectly on our resolution and it can be setted to be the default navi app. It works OK.
[MTCB Android Head Units Q&A] OriginalGriff:
iGo

iGo came with the unit, but without the maps - so at the moment it won't run (you need the app running to download maps, and you need the maps to run the app!) So I'm sorting that with the supplier ATM. Have to say that OSM And is working fine at the moment, but I'll try iGo when it works on my unit :D
[MTCB Android Head Units Q&A] MoshPuiu:
I didn"t succed to make default iGo to run properly. So, I have installed iGo NextGen (which is not limited by device resolution) and it is newer and better than the old one (in fact it is Primo). Also you can try TTS if you like it...

Hello there, remember me ?

Finally got it to work by pressing to copper ribbon cable on itself as it used to be. That ribbon cabble leads from the screen board to the the screen itself, behind.

After a few days of use, during a night drive, the headunit litterally started to burn from a transistor on the left side of the main board, and propagating.

Had to emergency stop the car on the side of the road, and disconnect the car battery.

Head unit officially dead. Suicide by fire.

Since seller continues to ignores me, I highly not recommand to by from Novoefine on ebay, which offered no support.

Good day,

Strange that HereWeGo is not working for you. I am using it on mine and it works well (with the exception of the options screen which does not display - known issue to do with the screen resolution). Only problem I did have was that I opted in to try the 'beta' version. This did not recognise the GPS so had to uninstall and then re-install the standard version. Have it set as my default nav app.

If you are having problems with igo gps not finding satellites.

1. If you already have a sys.txt in your igo folder, make a copy of it.

2. Replace it with the attached sys.txt file, or if you don't have one - put the attached sys.txt file in your igo folder.

Suzuki Grand Vitara Steering Wheel Buttons

Hi everyone!

I have bought an RK-A701 unit for my Suzuki Grand Vitara 2006. Before this, I was using CarPC with 7" touchscreen.

RK-A701 is value for money! (115€ on eBay)! Nice LCD and Touchscreen, pretty fast, GPS works perfect, wifi is ok, android 5.1.

I only have 2 issues:

1. I have connected the 2 wires of unit, WC + WC2 + , with my car's 2-wire steering wheel buttons, but the buttons don't work.

Even to the configuration menu, I try to assign buttons, but nothing happens. On 2 car's wires was connected the factory unit and the CarPC with JoyCon EXR.

(I can't upload any photos....)

2. The back 4-pin USB does not work. Device takes power, but no data. And also, in the menu, there are only 3 USB devices not 4. Do I have to configure something?

As I wrote above, the unit has Android 5.1 installed.
[MTCB Android Head Units Q&A] gmcmen:
There is normally a 3rd ground wire on the steering wheel controls that connects to pin 17.

If not try connecting Pin 17 in picture to Ground and see if the steering wheel controls work.

Thanks for replying! There is no 3rd wire :( I had already connected Pin17 to ground from the first time.

Is it possible not to need Pin 17 to ground? I didn't try without connect it.

I just tried one of WC+ and WC2+ to ground and when I pressed one button once, it worked like I keep holding it.... :eek:

Good evening at all.

I have an already working RK a701 mounted on a camper. One question: the first red GPS button connects me to the IGO installed navigator I do not have cartography. Since I've already purchased a navigator that works seamlessly on this radio, I want the GPS button to open my navigator. How do I program it? On the instructions nothing.

Hi AndGeo,

I'm not sure if this will help you, but I have recently connected my unit to the steering wheel controls. When 'teaching' the unit, I did not find it very responsive to the buttons. I sometimes needed to hold the button for a few seconds for it to be recognised. Once programmed, the buttons work as expected and respond normally.

It's possible that one of your two wires is earth and the other is WC+ Do you have a multimeter to check?

---------- Post added at 05:26 PM ---------- Previous post was at 05:17 PM ----------

Could someone who's head unit works try this?

1) With unit ON and at least booting, press and hold the power button (in my case, this is the volume knob) until the lights on your unit turn off (if they were on) or flash. Once they flash, keep holding the button for another 5 seconds.

2) Release the power button, and press quickly once more (within 1.5 sec) do not hold.

3) Wait. The device should boot into recovery. Do not press any other buttons during this process.

I am in the process of learning a bit more about this unit to share, it's in bits on my desk bricked at the moment! I am trying to get a rom back on it. Bricomann has had success rooting his device which is a good start. The settings password is 66668888 there's some stuff in there and then there's the settings xml you can export and import but not much in there :good:

The bluetooth tethering looks unlikely as the bluetooth is not visible to android only the MCU. I was thinking of adding a USB bluetooth adapter when I debrick mine!
