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

Chinese HU vs Parrot Asteroid Smart

Hi
I am currently using Parrot Asteroid Smart, generally I am satisfied with the unit, sound quality is great, BT and other features works good, but the HW is old and max. Android version is 2.3.
I'm thinking about upgrading to newer android and the only possibility I see is one of chinese 2din HU like Ownice C500.
Does anyone have experience if they are any cons of such change? What is the sound quality of C500 compared to Smart?
Any info would be appreciated.

I am in the exact same situation. I was happy with the PAS at first, but it became outdated and frustrating very quickly - the lack of apps supported natively, the lack of ram and storage. Even after rooting and installing Google Play store there are so many apps that can't be run on 2.3. Positives though are that the Bluetooth call quality and voice command is in my opinion unmatched.
I have since bought an Eonon Android unit (rooted and installed Malaysk rom) for my wife's car and the interface is great, the sound is reasonable and the app support is great. The Bluetooth however is terrible, to the point of being unusable, the person on the other end can either not hear or suffers from major delay. This is a known problem with nearly ALL Chinese Android head units and there is a hardware mod but not being very confident in opening the unit and performing the mod properly and potentially voiding warranty is a risk I'm yet to take with it. I also have an issue where the physical volume control knob stops working and sound can only be adjusted on-screen, this is usually fixed with a reboot.
I still have not found a reliable unit to replace the PAS in my car after reading numerous threads that has Bluetooth quality on par with the PAS. Hopefully someone else here can recommend a decent unit?

Joying 2GB Intel is the way to go

Why?

look over some of the various threads on XDA, and feel free to check out the official Joying forum - http://forum.carjoying.com/
For the most part i think Joying gets the least amount of negative feedback, they tend to have pretty good customer service, and they seem to so somewhat monthly updates. I have had the older 1gb model and I currently have the newer 2GB of RAM model, and I'm a big fan:
here is a video review
https://www.youtube.com/watch?v=KzGFDwSFj24&feature=youtu.be
https://www.youtube.com/watch?v=IUP4WGYHIaQ
but dont take my word for it, like I said, if you spend some time reading, you'll see a lot of the other head units have their fair share of bugs and complaints

If you want a fully functional BT interface, go with the Intel 2GB Joying head units. I think they are the only ones with a full stack BT interface available, the other Rockchip based units seem to have a somewhat hacked in BT interface which is limited compared to a full native interface, specially when it comes to how the Android OS can access and control it.
Install the apk from this thread and you have access to the standard Android BT settings screen, it is normally hidden in the Settings app but luckily it's not removed.

Thanks for the info
Few questions:
What is the BT handsfree quality with external mic installed?
Does the radio display station names? Does RDS and AF work correctly?
What is the general sound quality?
Does WiFi module connect with 4G router?

I use the head units wifi to connect to my phone as a wifi hotspot. Works great. BT handsfree with external mic is very good, at least according to those I talk to, I haven't been on the "receiving end" yet..
The sound quality is good, I'm still using the OEM speakers and they sound better with this head unit compared to the OEM head unit. Can't confirm on radio as I actually don't use it much... It does have RDS it seems, but don't know if it works or not. (radio where I live is garbage, nonsense content and music seems limited to whatever the top 20 list is...)

Thank you for the info. Which version do you use? I can see there are 3 different versions of 7" universal unit with the same hardware. The difference is that two of them have volume knob and the 3rd only touchscreen.

Both MTCD and Joying INtel have positive and negative feedbacks....
In terms of BT performance....both have BT Limited to MCU. Even you could pair from the BT standard menu, the functionality is limited. If i am not wront (correct me) both units CAN'T perform CALLS from BT by using google Now. Google Now recognizes correctly the name and it seems to start the call but never is initiated as it can not communicate with the real bluetooth Handsfree on the Headunit.

On the Intel units, the BT and wifi hardware is on the same board as the CPU, Android has full access to it. That is not the reason Google Now can't make calls. This is different on the MTCD units where the BT is a module which is sort of hacked in and Android doesn't have full access to.

I have bought Joying with Intel. BT handsfree works fine, although there are some other problems:
- no voice in Google Maps,
- when listening to the FM radio no voice output from nav apps except of Igo,
- I have connected Alpine active sub to the unit, sub works fine for first few minutes and stops, any idea why and what can be done about it? Sub worked great with Parrot, so it must be some issue with Joying.

I think if you change default nav app to your preferred one, you'll get voice output in FM radio.
For the sub - is the amp still ON after a few minutes when it stops? I have an active sub on mine and have no issues. I'd check on what your source for "on" signal on your amp is.

Google maps voice output doesn't work no matter what I do. As a default nav app neither.
Sub is powered and it works with very low volume settings, ad soon as I turn the volume up it stops working.

We got Google voice output working. Look into the forum.

Strange. Maybe I should reset the unit to factory settings. Reinstalling google maps did not help.
Any idea what is wrong with the sub?

(have seen a few oem ones) if so it would be hooked up with the sub RCA output ? Is the amp powering down ??
If so try hooking the remote line on the amp to an 12v acc line instead. (This is no different to the headunit remote 12v output just that if you switch the head unit off the amp is still powered on , this could eliminate a headunit problem ?)

As wrx216 said. I think it might be bad wiring. try a different SUB "ON" source. For example, I tap in the + wire of my rear speaker as the power on signal for the sub amp.

Google maps voice output still does not work. I did factory reset - it did not help.

I have updated the firmware and google maps voice works fine. But sub does not work at all now.
I have connected remote wire of the sub to constant +12V output (the same as amp. power supply) - it still does not work. I have also tried to change RCA input of the amp. - still nothing.

Eonon GA6150 BlueTooth question

Hello xda people!
I recently purchased an eonon head unit for my E46 316i from ebay. Specifically a GA6150 (rk3188), which was sold together with a reverse camera.
I am really happy with my order, and pleased with the HU's performance. I managed to connect succesfully my OBD adapter, my bluetooth phone and my wifi hotspot and all is working great.!
Although, I found out something which bothers me. I have purchased a Bluetooth RGB LED controller from ebay, in order to DIY install some LEDs in the interior of the car, and I wanted to control them from my eonon android HU. I can control them through my S7 Edge Android phone via the app called Happy Lighting. I have found out that the manufacturer of these controllers is called Triones. So my problem is, that when I open the app, it asks me to turn on the bluetooth, and allows me to press one of two buttons, allow and deny. If I press allow, a message will appear saying: "Turning on Bluetooth" or something like that, with a spinning wheel, indefinately. It will not stop and it will stay like this all the time, making the app useless, making me press home button to exit. All this happens, even though I know that bluetooth is actually on (I havent yet found an on/off switch for Bluetooth, so I suppose it is always on). If I press deny, then I can enter the app, but I am not able to see any of the bluetooth controllers, is there any way, to make the app think that the bluetooth is on? Or actually turn it off or anything? Would you please help me figure out what should I do? And one last question, is how can I change my screen orientation from landscape to portrait?
I will attach a photo of the details for the version of my Head Unit.
This is the link of the HU I purchased from ebay: http://r.ebay.com/aegMSa
And this is the link to the controller: http://r.ebay.com/aDfflI
While this is the app: https://play.google.com/store/apps/details?id=com.qh.Happylightgoogle&hl=en
Thank you very mych for your time!

Yep had 3 Paypal disputes with Eonon about that issue a year ago on a MTCB unit, I would imagine it would be the same with the MTCD
I think they route all Bluetooth information through the MCU and use non standard configuration of their Bluetooth drivers. So applications that ask to turn the BT on cannot as it is not configured that way.
This is something they were not willing to fix or were unable to.

First of all thank you for your reply, i really appreciate it.!
Second, damn it. Damn them! That is really frustrating, i've managed to find a bit more info digging around here and in russian forums. It's sad that i cannot use anything else via bluetooth other than a few OBD adapters and my phone..
I will shortly contact Eonon for my MCU update file and see if anything can be done there. Otherwise, i will see if anything can be fixed via a custom rom and xposed stuff.
P.S.: If there was any other android HU that could support full BT, i would gladly return my Eonon and buy that instead..

Joying intel Sofia units is a bit better with the BT, but do some research first.
Good luck with Eonon
From memory it to do with kernel drivers and BT stack and they would not fix
Also be careful with Eonon and returns, additionally PayPal protection does not cover car audio products.

Digging up an old thread
I would like to connect bluetooth accessories to my eonon new android 10 head unit (2020) - the above looks familiar as i cannot seem to 'find' the devices when searched for using the strange bluetooth 'app'.
Is there anything that can be done? I'd like to add a bluetooth remote (alternatiev to steering wheel controls) - but its not detected by the HU

Joying PX5 Android 8 4Gb Ram 32Gb - google voice services not working

I just installed a joying JY-UO138P4 (https://www.joyingauto.com/joying-l...ouble-din-car-audio-system-with-4gb-32gb.html ) in a 2006 Pontiac Grand Prix.
Most things work - I am still working out the steering wheel control wiring with Metra Axxess and Joying - I think this is an issue with Metra identifying the car correctly, I had a similar problem with an older metra unit on a Sony receiver.
One thing that doesn't work is accessing google voice services when I click on the microphone, I get a message 'Cannot reach google at the moment'. I am connected via wifi and can open the Chrome browser and get to google. All other internet access I tested works fine as well.
Does anyone have any suggestions on this?
p.s. I'll probably have other questions on improving the UI - would like a better blue tooth phone client, and something better with the radio.

Search the forum. This has been mentioned several times. Google voice currently doesn't work. Joying is working on it.
A lot of us have questions and remarks on the UI, on a lot of aspects, and on the functionality. Most/some of us are already pushing Joying 2 years for improvements. Some improvements and bug fixes came, others not.
Please help pushing by directly mailing to Joying ([email protected]) about your comments and questions, but don't think you're the first.
You don't mention your issues with the Radio, but if it is about layout: see here.
Those radio mods are made for the Sofia units, but work just as well on your type of PX5. I'm using one of them (and the PX5 models ending on P2 or P4 can use the exact same software)

Thanks for responding, I did find a rom on their site (have the link on my home machine) , not sure it is for these devices, just says for 2gb/4gb 16gb/32gb Octacore, but from the looks of it, it is an AOSP build.
After trying an older 'personal assistant' app AVX Extreme, I found out the google speech to text module is missing. - this thread (https://groups.google.com/forum/#!topic/android-building/Gu8c8JLMo6w) shows that it is not part of AOSP, so if we can figure out how to get the speech to text module installed, I think it will work.
As for the Radio, it is a layout thing, it is not a bad layout, but I feel it could be better somehow. I'd like to find a launcher that supports the OBD-II input for speed/etc, a nice clock, radio/volume control, and navigation
I see you also have a thread on the 8.0 build so I will follow up on there.

Dit you managed to get the steering wheel control wiring with Metra Axxess to work on your Joying? I also need a canbus decoder for the joying i'm planning to buy. Can you recommend the Metra Axxess, and is it difficult to connect the wiring?

Yes- I got it to work, though don't ask how I had multiple back and forths with Metra on it- for some reason the Axxess could not properly detect my car, metro told me the instructions printed and on the pdf could be wrong and I should try ""VOL UP, SEEK UP, BAND, MUTE, VOL UP"" - but that didn't work. At one point I got frustrated working on the car, and reset the Axxess for the 20th+ time, and didn't notice the steering wheel was turned, so i hit the buttons 'upside down' - I am not sure the combination, but once that happened everything is working good.
In my car, two of the buttons overlap - so I have 6 buttons I can assign instead of 8, but the important one (Seek/Volume/Mute) are mapped so I am happy.
I am not using CANBUS on my car, so I can't speak to that, though I am trying to find out if there is any information anywhere on connecting to the build in HUD in my car.

HeadUnit doesn’t support stereo sound

Hi friends,
The head unit I have right now does not support stereo sound, and when I play any music from my iPhone the sound comes from both left and right speakers at the time!
But when I play from the usb using the music app, the stereo sound coming from the right and left speakers with HD sound that means the Bluetooth apps don’t work correctly in my head unit.
Also, when I checked the developer option, I found that the setting sets in another option not as stereo sound, I tried to solve this issue from the developer settings, but when I change the voice type to stereo, the setting returns to the original.

Really thank you for your attention.
No, for one reason I have another car, and the Bluetooth working smoothly in the factory head unit. supporting stereo sound and HD sound. Meantime I opened the development options and I saw that in the Bluetooth Audio Codec setting the sound is not stereo. I tried to change it to stereo but the system didn't allow me. also, no build number and I opened the Dev options using a shortcut app in the store. it is really Stuped Headunit.

FYI

Well... OEM unit may work different, because they are completely different.
It´s a known fact, that those iPhones have problems with most of the Android head units.
You should contact the seller and ask him for a solution. May be there is one.
...btw: This is a quite old unit with Android 8. May be you can update your unit.
Look for STM32 thread in here.
