Eonon Android 5.1.1 bluetooth issues & canbus issues

hi guys
new to the forum, hopefully someone will be able to help me
my unit has stock MTCC-KLD6-V2.97 Aug 02 2016 with a RK3188 and 1024x600 screen
Firstly the Bluetooth is not working, quite a lot of apps hang at the part where it try's to turn the BT on, especially one app i really need to work.
I honestly don't know what model of BT chip is installed in the head unit, apparently its BT 4.0 as listed on there website
I have been into the factory menu and changed the BT from WQ_BC6 to WQ_BC6B (as suggested somewhere in this forum) but it has made no change and the BT is still hanging at powering on.
Eonon have told me that the Bluetooth only work with devices that don't require a pin and the radar detector device i need to connect does not require a pin but still it does not work.
Not quite sure if eonon has set the setting wrong and i need to change it or i need to goto a custom rom or I need to pull the unit apart to find out.
Found someone else having trouble getting there ALPconnect app to work aswell on these units, in know ALPconnect wont work on older unit like the 4.4.4 as they only had BT 2.0 and the ALP BT only supports 4.0, but this android unit has 4.0 so it should not be a problem but it is.
sterod said:
The app I use, ALPConnect, does the exact same thing. Fortunately, the hardware on mine includes a hardwired speaker and GPS setup that work standalone. The benefit of the app was to get a nice big visual notification of a trap, as it would come into focus, duck the audio and play an alarm. It would also report the frequency of the radar and the type of laser hitting me. While I can get by without all that, I can't have the music blaring like I usually do, as the little speaker is only so loud and the Joying head unit doesn't have Mute Input wire to duck the audio.
While this is going slightly off topic, you may want to look into the AL Priority, it can interface with your V1 too and you will also gain laser protection. This thing has saved my a** countless times and paid for itself already many times over.

Secondly the control menu in the android head unit for accessing the cars buttons via cambus does not work, all steering wheels button seem to communicate back and work, but i cannot set my clock on my mazda 3.
Also have noticed that the radio wont mute when notification occur or when using other apps like google maps, no way to set the different volumes in this stock rom. Have played around with the factory menu volumes but it makes no diffidence.
Is it viable and worth changing to a different ROM, like Malaysk? or should i message eonon?
any help would be much appreciated
thanks

I'm having exactly the same issue with a Pumpkin MTCC-KLD6-V2.91. (RK3188/1024x600)
The device I want to pair with appears in Bluetooth settings (with a phone icon?) but connecting to it does nothing. It's just a Bluetooth SPP device, like so many other devices.
Malaysk's ROM (from 7/25) doesn't change anything here.
Any suggestions would be most welcome.

Waiting on a reply from Eonon, but initial news is not good.
Some serious BT issues in this model the MTCC
Anyone know if any Malaysk's Rom's avalable for the MTCC-KLD6-V2.91 that have no BT issues

I'm having the same issue, though my unit (MTCC KLD6) does not show any devices at all to pair with, and the car unit does not appear on my phone.
I'm wondering - if I take a usb BT dongle and attach it to the usb cable, would that work?

I think it might be another issue with your BT, it should connect to your phone at very least.
Have you had a look in your factory menu to see if the MCU has the Bluetooth option set?
Password for me was 126
Unfortunately the unit does not support external USB Bluetooth and probably never will, unless the manufacturer MTC/Klyde adds the required drivers to the unit or a Awesome developer by some stroke of luck here adds it to the unit. I doubt to see the feature in this unit

Thanks for the reply. Yes, i checked to make sure Bluetooth was enabled in the system settings. I've tried a few of them (change setting, reboot, attempt pairing), i guess the next step is to try them all one by one to rule that out. I've sent an email to the seller to see if they have any ideas.

The vendor told me to connect the Key-1 & Key-2 wires from the canbus to the car, not sure why they'd think that would solve BT issues?

Did this fix the issue? I'm unable to see any Bluetooth devices and other Bluetooth devices don't see it.

Sorry to dig up an old thread
I have the Eonon GA2180a (android 10) - and having similar issues to here
I want to pair a bluetooth remote (read, steering wheel controls) to the head unit, but the bluetooth search just shows blank! I can connect to it using my phone but it appears some things are hidden to connect to with these android units? Looks like the bluetooth 'app' is the only way to connect too, theres nothing in the android settings to access a bluetooth menu or anything.
Did anyone get anywhere with this ?
cheers

I had an issue connecting; however, found that it was a port problem. Switching the port fixed the issue.

We're you able to get it working with the Accord? I'm thinking of getting this phone, but I need it to work with my Civic.

Also won't work with Chevy Mylink system. Huawei Mate 8 and Nexus 6P work fine, Pro3 does not. After connecting the phone, the car detects it and asks to connect, and when selecting yes, it return the car infotainment to what it was on (radio), and not the android auto screen. On the the phone there is an Android Auto notification, which cannot be clicked. The phone switches to a USB screen stating that it is in charge only mode.
Anyone have any steps to get around this.

Can you clarify the port change you made. Both my car and phone only have one port, so I am not sure what you mean by switching ports. Thanks.

VW has confirmed that my USB port is faulty and ordered a replacement. I have two USB ports in my car, the front one does not work properly, where as the rear one works just fine.
If your car recognizes your phone, your phone is charging, but not connecting, then, most likely, one of the pins of the USB port might be loose. Have your dealership check it.
Hope this helps!

Thanks for the clarification, i understand, you are physically changing a port! I doubt this is the issue in my car, as the car is in regular use by many drivers. 3 other phones work. A nexus 5, a nexus 5x and a Nexus 6P. You can see apettern there on what phones we prefer! I am also currently trying the Huawei Mate 8 which also works. But the Le Pro3 (x727) fails every time. A bad port would likely not work or be intermittant on at least some of the other phones.
I did try other cables, including the one that came with the phone, no difference. Did your dealer let you plug into a car on the lot, to verify the phone will work?

No, I just started the issue and they were able to test for it.
Have you enabled USB debugging in dev options? Try disabling it, try MTP/PTP options while connecting. Also, try clearing data or reinstalling Android Auto or verify the app permissions.

@Karthi14 I work for American Honda (HQ) and I can check regarding the 2016 Accord for you. What trim level do you have? I'll check on several trim levels with the DA audio to be sure.

Is it safe to assume that it will work with all 2016 Civic trims? I have an EX-L.
If it's compatible, I am going to get the X727 on Black Friday. Thanks in advance for the info.

It should work fine with that, and I'll check that civic trim today to be sure as well.

Yeah, I think I have tried everything, which is why I decided to come over here to the smart folks for help. I enabled USB debugging, turned off battery optimization, checked all permissions. It is interesting that when it connects to the car USB port, the USB computer connection screen pops up, which is where you set MTP/PTP/Charge only, and it is set to charge only, and the options are grayed out, so I can't change them. With USB debugging enabled, it allows those to change, but it still makes no difference. It may be the combination of the Chevy AA implementation and the X727 ROM. It seems other users here are getting connected, so change the car it works. On my end, change the phone and it also works. Bummer. Will have to sell the Chevy or the phone. !!

I tried my phone on a 2016 Accord Touring: Android Auto worked fine.
Tried on 2016 Accord EX-L: Did not work. I tried all options on my phone; MTP, PTP, Charging, USB Debugging On/Off...No bueno. I'll look into any possible software updates for the audio unit and report back.
Tried on 2016 Civic EX-L: Android Auto works fine.
Looking into the Accord situation, I don't see any software updates for 2016 Accord. There are two different audio head unit part numbers used for 2016 Accord, both made by Clarion. The Touring, EX-L Navi & EX-L Navi V6 all use the same head unit. EX-L & EX-L V6 use a different head unit than the others. That may be the issue, but I don't know the root cause of the difference. Still looking into things.
Waiting for feedback from Clarion tech line rep at our offices in Ohio. I sent software version info for both units to him, so I'm waiting to see what he says.

There is a software update available for the audio head unit in your accord. I got the update file from our product development group here and I wish I could send it to you, but it's 19gb. Probably the best thing to do is go to your local honda dealer and have them update it for you. I imagine they would charge you for that, but I don't know for sure, and I don't know how much.
The update took about 30 minutes or so, and I can confirm my phone now works on it.
To summarize, my phone worked on our 16 Accord Touring and now the 16 EX-L after the update.

Hi Honda John,
I took my Honda 2016 Accord to the dealership, they said that they couldn't find any software update for the audio head unit in their system, could you please guide me towards my next steps?
thanks!
Ashmit

I factory reset my Honda Civics Bluetooth system and I can add my LEX727 to Android Auto now. It may also be because I'm on TARS ROM, but I never got that far before until I did the factory reset.

Which Honda dealer is it? I'll contact our Honda DPSM for your district and have them work with the dealer. According to our Product Development group, the update files are available on the server, but at this point an official Service Bulletin hasn't been published directing the dealer to look for the update. it's supposed to be coming out soon, but no specific date.
I'll keep you posted in it...

Hi John,
Thank you for getting back at me. My dealership is Valley Honda in Naperville, IL. They said that they weren't able to find any softwares in the bulletin, and my Car's software said that it was most updated one. I would appreciate if you could contact the DPSM and share with him about the issue.
I am still under 15 days of purchasing this phone, so I have the opportunity to return the device, if this does not get figured out. I need android auto for navigation as I am seriously direction impaired
I really appreciate your help!
Thanks,

Hi Ashmit, the Clarion engineer told me the update will probably be released by the end of this year, or early next year. Evidently, Honda will send each dealer two thumb drives when the service bulletins (one for Pilot, one for Accord) are published.
Unfortunately I think that's outside of your phone return window. If you'd still like to PM the name & number of the person you've been talking to, I'll give them a call & explain the situation.
I'm sorry it's not better news.

New Android 7.1.1 PX3 Unit from BonRoad - Any Info or Feedback?

https://www.aliexpress.com/store/pr...32699671881.html?spm=2114.12010612.0.0.KbDCzA
The UI and other specs are very similar to the HotAudio test preview (thread here). Has anyone had a chance to get their hands on one of these yet? I'm deciding between this or a Joying unit.
Any input is appreciated!

PX3 RK3188 Android 7.1.1 DVD VW GPS 2G ram
Just received and installed this Head unit in my vw touran 2004.
It looks like the specifications are the same : https://fr.aliexpress.com/item/Pure...32582906631.html?spm=2114.13010608.0.0.UFTkAD
The unit is a Bonroad C1120801A4/A5 (RK3188 Android 7.1.1 Lecteur DVD de Voiture pour Octavia Fabia Praktik EOS GPS Navigation Avec 1024*600 HD 8 "
So far, i'm satisfied with the unit :
- Radio is now working and stable .RDS works fine (with the last DCMU update). (You need to put a double fakkra antenna plug to get the radio stable on vw cars)
- GPS IGo is fine but not in French, Waze great
- canbus is functional
- Wifi rear camera ok
- BT external micro (mono) installed, i need to shout/YELL (it is an issue...)
When calling, both mic works (front mic and ext. roof mic)
google voice research unusable
I'm waiting for documentation from the supplier as there were no instructions in the box.
Do not hesitate, if you need more informations, pictures and tests. :good:
I tried Kingo root but it failed.

I also bought a car radio on aliexpress similar to yours. Px3 cortex a9 for ford focus c-max.
I have exactly the same worries as you with the microphone, the one integrated in the facade I have to stick my mouth on and scream.
The one who plugs externally is the same thing.
Many people talk about a worry with frequencies that are not the same in china and here
300-3400 for china
50-7400 for others
If you can root your device you can change the frequencies with Pimp my rom.
Personally I can not root it.

Thanks for the feedback. What's the boot time on this thing? Does it have a sleep function similar to Joying units?

About 15 to 20 seconds to boot. For sleep functions, I have nightlight or 15s 30s 1mns ect ...

I've the same unit but it doesn't detect OBDII adapter. Any solution?

After trying everything to get the microphone that works for the handsfree kit, I decided to cut the 4th leg of the bluetooth module and solder a mono microphone directly on it. This was my last option because I did not have the c32 connector. This has been a success. People hear me very well now.

I have ordered this one - https://www.aliexpress.com/item/4-C...32691433062.html?spm=a2g0s.9042311.0.0.MbBrvn. Waiting for the the item to arrive. The seller would ship it on 17 July 2017 (Monday).

Can you try the following and see if this gives you root access:
Goto factory settings and instead of typing 126 type *#hct#root#
This may give you temporary root access. Now you can install supersu or magisk to make the root permanent.
Note: I don't have this device or have not used any other Android HU; so I have not tried the steps mentioned above. I found this on the internet. Please try and let us know the result.

Is your Bluetooth scanning OBDII with this ROM ?

Anyone managed to fix the bad Bluetooth call quality? Any luck with getting root access?

Hello, I bought this unit, but the 9-inch model without buttons and I do not use the search for voice, the free hands works perfectly for me, but for voice searches they do not work with the internal or external microphone.
Nor can I get programs with self-starting like the Radardroid service start only with the start of the radio, I have to manually activate it at each radio start.
I also have no rear camera, only parking sensors, and every time I put the reverse gear turns off the screen and the voice of the radio to try to connect to the back camera even if I do not have it, this did not happen with my previous radio with android 4.4, only with this new one with android 7.1.2.

Well you're right, if I have the auto sleep option enabled, but programs like Radardroid can not start automatically with the radio, I always have to start them manually.

Hi everyone!
I have a similar unit.
I think that the problem is with android version. In our case 7.1.1.
I had a problem with my OBDII reader and I updated my unit to 7.1.2 and fix it
Now with 7.1.2 I have the same problem with microphone and also I have a problem with USB cameras. Only the DVR app can connect with but only the first time. If I close the DVR app and open it again, camera dont work.
I want to use the USB front camera with Mapillary and iOnRoad but I cant.
Any idea?
Where can I donwload a previos android version? for example 5.1.1 or 6 perhaps its would fix the problems.
Thanks!

I've had a Hizpo 7" no dvd with buttons mcu xrc 2.54 android 7.1.2 2gb 16gb for a week. Came this way so I can't say about previous versions.
My bluetooth microphones (both) work fine for me, calls hear me fine. Even just the internal mic seems good.
I haven't had any bluetooth connection problems.
Android does not see any microphone, there is no speech input in keyboard settings, google voice search hears nothing. Voice recorder apps hear nothing.
Tried a usb mic but that did nothing.
Can't get usb camera to work for DVR. RCA CVI cam works in DVR but doesn't record, does not work in FCAM app however, though rear does.
OBDII worked fine when I first tried it, haven't messed with it since.
Display clear and good.
Haven't seen any bog, even when running nav, audio, video etc.
Audio is so so, lots of noise. Radio reception seems great and RDS works too. Needs an amp.
Wifi reception is great, just a little antenna on the back.
I really like it but for the lack of voice search. It's really fast, I have a load of apps and still tons of space. Runs everything so far.
Nearly instant on, radio is playing in under 2 sec (probably 1).
GPS works good so far, finds my location in maybe 10 sec or less usually. I haven't been thru Pittsburgh yet to say how well it keep its signal.
I just got MTCtools and dialer and will start messing with them tomorrow, hopefully I can get a mic input to android and get voice working, then this will be really great!

Custom or modified rom to enable full bluetooth use?

Hey guys so I have an Alfa 159 and bought one of these head units:
Edit i cannot post a link however its the generic A-media Auto alfa 159 head unit which can be found on google
now I was speaking with a friend of mine who explained that the roms are "cut back" and removes some features and full blurtooth control/ support is one of them
I am reasonably ok with computers but never ventrued into any sort of custom android stuff and the extend of my knowledge is " i know you can get custom roms" i hdon't know how to do them or use them etc.
I have some bluetooth modules i can control from my phone in the car (lighting and actuators) but would love to be able to do it from the head unit
Would it be possible to get a custom rom for this head unit and if so any guides at all?
I would like to point i did have a search but honestly i am not totally sure what I am searching for and searching sepcifically for this head unit didnt help.
Thank yoiu very much

It's not so much that the ROM removed bluetooth features as much as it is how the bluetooth module is integrated to the HU. There's 2 system boards that make up the HU. The SoM has the Android system and is basically a tablet motherboard with only a display, audio and USB connection. The MCU provides a USB hub, audio preamp and power amp, connectivity to the car and the bluetooth module. The bluetooth module is treated as a headset controlled through a serial connection with AT commands and this is where the problem lies with using bluetooth with any apps other than the built in ones. It works for ODB dongles so it is possible but if the functionality you're looking for is not already implemented I doubt someone else would be able to add it to the MCU ROM. All I can say is try and see if it works.
Maybe you can try to connect a USB bluetooth dongle the issue here would be Android drivers.

Thank you, sorry for late reply.
A friend of mine figured out with his that it was "nuked" in the software allegadly. the bluetooth module is a generic module but unfortunatly I am not massivly clued up on reflashing roms or even where to start especially on a head unit which is a shame.
My friend unfortunatly has since moved country so I can no longer ask him to take a look

I don't suppose anyone else might have an idea to this?

this comes up often apparently nobody give f*ckall to address this issue.

^ Thats a real shame

i know, my radio is great, does everything great. I just want to connect bt to my ham radio and use this as the head unit. and I was thinking about using those bluetooth valve stems so i can see the air pressures in my tires, looks like those wont work either.

Have you considered that these units work for the intended use and if it doesn't work for some obscure use case the desire to solve a problem for single users is limited. To expect others work on an obscure problem for you seems a bit entitled.
Have you considered taking the lead on this issue.

Bumping to see if ANYONE has came up with a solution, maybe an external dongle?

Junsun V1 pro 8/128 - no app sound

Hello everyone,
recently i installed a Junsun Head Unit in my Audi TT MK2 (2012) with the bose system.
I had a xtrons PX5 before that worked like a dream until the touchscreen died.
The JunsunHead Unit works fine, but there is a strange behaviour i can't figure out.
Everything is connected through the quadlock and a canbus adapter from the seller, also there is a aux harness connected. pretty much standard stuff.
My problem:
The integrated radio app has sound. Music via Bluetooth works also just fine.
Every third party app like youtube, spotify, waze, maps, ... has absolutely no sound. nothing.
Googling my problem wasn't really helpful. Connecting the AMP CTRL Wire to ACC oder every other 12V wire to activate the bose amp in the trunk doesn't do anything, still no sound. And yes, the amp is working just fine, when i connect the amp ctrl wire to the powered antenna while using the radio app you can hear the difference in the sound qualitiy because of the amp working, but like i said you also have sound without the connected amp so there should be sound in any other app also, right? I don't want to listen to radio stations all day - i want spotify
In the hidden menues every setting looks just fine, everything works except the sound in app.
So my guess is the firmware, i already contacted the seller but he didn't responded yet.
Is there a newer firmware available? Or do any of you guys have any idea how to fix my problem?
One more thing: how to do a factory reset on this unit? Is there a code or a special way to press the touchbuttons...? Is it the "erase all content" in the factory settings?
Thank you so much in advance!

no idea?

How is audio output connected to your car/amp? SPDIF coaxial?

Android head unit. Some apps no sound. Radio app has sound.
Hi all. I stumbled upon these forum by googling my issue. So far I haven't found any answers to my problems, so hoping for some help from the great people on here. I have recently installed a seicane 10.1 android head unit into my jeep wrangler...

I've seen this thread. Didn't really help.
Everything is connected through the OEM quadlock (with bose) + the canbus encoder and AUX left/right in the wiring harness.
Spoke to the seller several times now and he has no idea either. He's sending me a new firmware the next few days to test... otherwise i'll send the head unit back. Must be some software issues cause some apps have sound, others don't... doesn't make any sense to me

The radio app is only an interface to control the radio hardware. Bluetooth may be the same. So it makes sense.

Hey everyone,
little feedback after updating the Headunit with the newest firmware from junsun:

Happy to hear that it wasn't hardware related.
