Hi,
I've just purchased one of these head units for my car. I can connect my phone to it via Bluetooth just fine for calls and music, but I want to connect the head unit to my ODB2 bluetooth dongle so that I can create a Torque dashboard for it.
However, when I go to the general settings, Wifi is listed but Bluetooth is not. I've searched and searched but there is no way for me to connect the head unit to a Bluetooth device. I've tried various third party apps that claim they are able to enable Bluetooth and connect to devices, but they all just seem to hang when I try to enable Bluetooth. Tried a system reset too, but that Bluetooth option is still missing from the settings menu.
Please can anyone help?

I'm also interested in knowing this. Torque doesn't seem to detect my bluetooth ELM327 at all. I also attempted to connect a USB-based ELM327 module, and Torque seems to detect it, but it doesn't work beyond that, and the headunit gives me a low-power warning light.
Hi did you get anywhere with this I have the same problem can't get Bluetooth options to show
I have exactly the same problem. I'm running a PX5 unit from Witson. Custom built for a Koleos. MCU is not a standard MTC device. I have no bluetooth option available in the settings and the stock bluetooth app does not display any search option whatsoever. It seems that it broadcasts itself for other devices to detect it but you can't search for devices. Seems like they may be handling the bluetooth via the MCU directly and not via android which is strange because they openly claimed that this device was compatible with the OBD II dongle that I purchased. They even shipped it in the same package. Will keep looking and post if I find anything.
I had the same problem with a different Chinese head unit. Solved by buying a WiFi ELM327 dongle which connected fine with the head unit's built-in WiFi.
Update to my earlier post...I managed to get mine working over BT with the WITSON unit. In the end I had to disconnect my phone completely and reboot the unit. Then I found a search option on the dialer page. Searching found the OBD II module and I was able to pair with it. After I was paired with it I was able to add my phone again and both can run in parallel. I have not been able to test much but it seems like this continues to work until the unit goes into a deep sleep and shows the startup logo again. If that happens then I need to go through the learning process again. Meh...
Hi friend, just a question, in the dialer where did you find the search option I cant find it in my android radio??
If you have the swm 8802 you cannot connect to obd2 this requires bluetooth 4 and the 8802only support bluetooth 2
Always Connect ODB First
The ODB readers are a tad picky but they connect using the same menus as any other BT hardware (headset, speaker, etc). First, turn on the car ignition, do not start.
2. Make sure no other BT equipment is connected to the head unit or even on & near by.
Next, place the head unit in searching/Discovery mode and then & only then plug the ELM BT Module into the car ODB II Port. Most cars must be 96 & newer. 95 GM with for the plug but won't work. They're usually ODB 1.5, don't ask, your screwed.
Finally wait for the module to pop up and ask for the code, it's 1234 not 0000.
After your paired, THEN open Torque and let it connect. Don't start the vehicle till the car icon stops flashing.
You should be good to go from then on. If you ever have problems after that. Make sure the app is totally closed, force stop and then follow this procedure again.

Mine connected no problem. Did it just like I do on my phone. I just got mine too though. Could be an update maybe
the original question wasn't answered and I have that problem too. I don't have a Bluetooth discovery/search option anywhere. the small bluetooth-like icon on the main panel just changes the color of the leds.
so can't connect new phone. although Bluetooth seems to be working, since an older phone, already paired, is still working.
Following this as my head unit is same. Theres no blietooth menu/option but it connects to a phone.
Ive tried a third party bluetooth manager but all that says is bluetooth disabled by admin??
A fix
That happened to me trying to add and ODB2 bt dongle. I had to use the app for bluetooth linking provided by the head unit. When I purchased the unit, I changed the bluetooth discovery and pairing code to 0000. Well, changing it to 1234 allowed me to add the ODB dongle.
I saw it on a YouTube video, and well, it worked for me. (And no, no native bluetooth option, came disabled for my unit as you said)
Hope it works for you too.
same problem with me
Hi sir did you found solution for this problem. I also have this problem with my native bluetooth. when i turn open system setting bluetooth missing. i try to open using shotcut and found shotcut to turn on bluetooth but when i turn on. it do nothing.
I can play music, make call using bluetooth app provide from head unit. Problem is i cant use it with OBD2 . same with your statement this bluetooth only stream signal to other. this Head unit cannot find other bluetooth.
Kindly please assist me. did this head unit still have hope to turn on native bluetooth or not. I still search many post regarding this issue. But issue bluetooth like this not many discussion.
Hello there,
My problem is some how different. My hu use the bluethoot to find the obd2 adapter but there is no dedicated pair button. I can pair my phone for calls and music but connecting from phone to hu.
My unit is a 8227l from seicane.
Has anyone any solution? Thank you!

Change the pair code in the bluetooth custom app provided, to 1234 and try again.
I had this happen and I think I figured it out.... in factory settings there's an option to choose bluetooth connect automatically or with pin. I checked with pin and was able to pair. I think the options are reversed in the settings
I have the same problem i can't connect to the android 7.1 car head unit any more , the bluetooth setting is missing , the wifi settings appear but bluetooth doesn't appear any more
Anyone can help me to fix this issue please ?

I bought a bluetooth usb adapter and I can't select it on the system. I think this would be the way out, but we need to replace the driver inside android. Does anyone have any ideas?

I have a Teyes Spro with the same Bluetooth issues as most on this post describe. Did you find an answer to your usb adaptor to solve the Bluetooth problem? I was told to add a line to the config.txt file but cannot locate where to access that to add it.
Bought a Teyes Spro headunit and I have a problem with Bluetooth discovery on my obd II and tpms modules. Does anyone know what is in the "Developer" tab? It is password protected not accessible. The 168 factory access code does not work for it. Anyone know the password?
Hi all, I bought a 9 inch android 7.1.1 head unit from Seicane (yes I know they aren't the manufacturer, just a seller, I haven't worked out who the manufacturer is).
The built in bluetooth is only for phone functionality and A2DP. I was hoping to add a USB bluetooth device to it....but the bluetooth option is missing from settings. Is there a way to enable it? I'm aware it may not have drivers and it may not work, but I'm hoping (as it is a bit of an unknown) that its just the settings option missing and it will work if I can get that in.
Any help much appreciated!
I often see thread asking for device info screenshots.....so I will include them just in case lol
I like to know that too, I have the same problem and unit!

I have found things on adding bluetooth in, but I can't get root on the unit. Seicane are insisting they are the manufacturer and won't provide the firmware
Also can't get ADB to work over wifi, and USB seems to be stuck in host mode

Click on the Call Icon. You will get the Bluetooth connection settings there. Please Note: For all car units Bluetooth is always on and cannot be disabled.

Hello, it's 2021 but it looks like there is still no solution to this issue. I have an Allwinner T5 and I am faced with the same problem. I want to connect the head unit to an OBD scanner via Bluetooth. The issue is that, if you go to the network menu, Bluetooth settings is not available.
Currently I have an inexpensive head unit Allwinner t3. The Bluetooth OBDii doesn't connect. Was able to use the Cheap ELM 327 and both pair and connect with my iPhone. My android HU will not connect. Says it pairs with both 0000 and 1234.
Too me, it appears some software must be missing. My HU doesn't allow me to reset, but reset to where it was when I bought it.
Was going to buy another OBDII bluetooth scanner, then I saw many people having the same issue.
Anyway to verify the proper software on the head unit?
On another thread, someone suggested going into Config Info., in the settings, from Bc6, to BC8. Didn't and it didn't work. It also changed the Android Bluetooth name from CarLink, to iTop blah blah. Changed it back.
Does anyone know if we're missing system files on these android head units or anything else?
Same here i have T5 Android 10 but couldn't find the BT menu to setup OBD reader.

Hello, the BT menu should be a BLUETooth App. Just like picking Radio, Weather, YouTube etc. You might have to add one if it didn't come as a default. Others have said to add your OBDii first. i.e. do not add your phone or other bluetooth devices. If you're lucky enough to get it going and it works, wahoooooo! if not, keep looking like the rest of us. Basically, we've been had.

Thanks. You are right the bluetooth app is there and I could find my Konnwei OBD reader and linking it works. I also downloaded an app called Bluetooth finder and I could also pair using that.

What obdii app are you using with your konnwei 902? Does the app work on your Head Unit? Not just come on, but does the reading work? Unisoc Chip SC7331e quad core isn't a name brand. Type that in and see What brands pop up.

In case you don't know, you need a OBDii App on your head unit to work with your OBDii, unless they have one. If they do you still down to download that via Google play.

Hi, i have problem connecting with the obd2 using the original bluetooth app, it says that pin or incorrect key. But when i downloaded an app off playstore which could allows me to use my own pin (1234) i can connect to the obd with no problems at all. but when i open torque or obdlink app it tries to connect again using the original BT app which will then have the incorrect pin or passcode. My question here is how can i change my bluetooth default pin from 0000 to 1234? I'm using an android 7.0 headunit.,

Hello. I bought from AliExpress android headunit for audi a6. In main manu it have "phone" and there I am able to connect phone for calls and music play. I wanted to connect obd2 bluetooth adapter to this android unit but cannot enable bluetooth...
forum.xda-developers.com
What app You downloaded for Bluetooth?
I just bought this Android 10 head unit from eBay, which claims OBDII support, and even shows a ELM327 Bluetooth scanner in the description. I have that exact same scanner. Problem is, I have no idea how to connect it to this unit. The seller isn't helping. I think it's a language issue, because he keeps answering in ways that have noting to do with my question.
If I go to Bluetooth, there is no option to list Bluetooth devises. I can connect my phone via Bluetooth without any problems, because I do that on my phone's end first. But with the ELM327, I can't do that (there are no buttons on it, you just plug it in). I need to do it from the head unit first, but there is no options that I can see. I installed Torque, but it won't work without first pairing the ELM327.
I know the ELM327 works for a fact in my car's OBDII. The pull-down menu doesn't list Bluetooth devices either. If I go into Settings/Bluetooth, the only options are auto connect and auto answer. Is this an Android 10 problem? Am I over-looking something? Please help. I may have to return it for false advertising.
Try going into the extra settings with pin 8888 206 5678 and under one of the menus you can select other options to put on your menu screen. Look for obd and select that. You can then pair from this

How do you go into extra settings? I've looked everywhere, does it specifically say "extra settings"?
Could this menu be it?
The little settings cog on that screen. Press that and enter one of the codes. Probably 8888. In this menu you need to find the options to add to your menu screen. You need ‘obd’
That’s how I did it
I have a similar question as well, i have been in my extra settings and I cant find any bluetooth

If your referring to pairing to an obd device then you need to add ‘obd’ to your menu screen. I’m not sure which setting it’s under, if you have a look through you’ll find it

honestly I could careless about the odb2 I am just trying to connect different things to my unit, i tried headphones, odbii and the main thing I want connected is vero vn7500..its a ham radio
The question I think we should all be asking is, what version of Elm 327 does our head units require, and what version does our OBDii supply. Is it, ELM 327 V1.4, V1.5, V2.1, etc. I've read that V2.1 doesn't work well. Also, my phone uses BLE 4.0. That seems to work with my ELM 327 OBDII from Obdation. Here's a blog: https://blog.caristaapp.com/the-truth-about-obd-adapters-e98ddf022bf8 Both the article and the store I bought the elm 327 mini says something about Low Power. Well, the BLE 4.0 is Low Power. How can we determine if the Head unit, app and elm 327 supports low power or not?

That's not correct.
The truth about OBD adapters is not in that blog. These obd adapters are knock offs, using stolen IP/code.
The real issue is that the head unit resellers code code the units to require a specific obd knock off adapter that they sell.
New member, the information is covered in the forums, we can chose to read it, or not.

MarchNZ, thank you for your comment. I stand corrected. So, what's our recourse? Do we buy better products, root the device or give in to the cheap suppliers? While I've been researching the cause and fix of this problem, I went back to the supplier and asked how much their obdii adapter is. Honestly I bought an obdii from Obdation for $10. Bought the HU for $179 (dashradio on eBay). They want me to buy their obdii adapter for $69.00. The picture looks exactly the same. Have no way of knowing what's on their obdii. Is their away to see what's on it, like an Eprom reader or something?
Already ordered VieCar BlueTooth 4.0 Dual obdii adapter. My guess, which is probably pretty good, that won't work either. Thanks in advance for everyone's advice!

Genuine type OBD adapters exist, such as an OBDLINK type, SX = USB or LX = BT.
They may not work with cheap Chinese origin greybox Android head units without mods.
My unit is an MTCD type, using a USB OBDLink SX (USB), connects every-time and is blazing fast. The SX also works but is not as fast or reliable to connect.

Hi, merry christmas to all!
I have a similar problem.
I am trying to install a Android 10 10" radio in my car.
The seller (CN) has no idea (they only want to sell, my guess)
I can't get any OBD dongle paired with the radio.
I found the hidden settings for BT by using the search bar in settings,
I set the code from 0000 to 1234, also unmarked the "auto connect" so I get the code input requester.
But while I am typing in the code, it disapears and tells me, code is not correct.
You can try it as fast you want, also to the point you only have to klick "ok" --- but it will not work.
I also tried a USB keyboard, so that onscreen keyboard will not interrupt.
Didn't help.
I show it in the video
Does anyone an idea? A special App?
Why do they make it so hard? They know, that many people want to use the Android device like it is able as a phone or tablet, specialy in a car with a OBD2.
IMO that’s deliberate with a bad mind making it harder and harder to use and config a system.
Then we also don't need the Playstore anymore, just bloodware the derives and the user has to eat it like it is. We are closer and closer to this situations.
What do the developer think? ANdroid is gettig worse and worse in the free usability.
Btw. my dongels I own myself:
- KONNWEI KW902
- vgate iCar Pro OBD2 Bluetooth 4.0(BLE)
And they work with all phones, tablets, laptops - also with DDT4ALL and other programs with no problems.

Even though my car doesn't seem to be connected or at least doesn't show it in the bar the odb2 works with the torque pro app.
And the only way I could reach the Bluetooth settings was with a Menu entry in the fcc launchers settings...
But that didn't help either because I didn't even get a "enter pairing code" prompt.
maybe that helps too...

These Apps also don't help in any way, as the system behind can't understand the dongles.
Is this the product of incompetence from the Android Developer or did the Chinese srew it up?

2)ADAS function, with all app that i tryed it doesn't work, and I see the DVR inly with one app
3) TMPS, the original app don't work, but i resolve using a app StoreBao USB TPMS
4) Dab, I search an app that work offline
5) OBD, I try the app Torque or dashcommand, but obd2 Bluetooth adapter doesn't connect
6) Voice Comand, work only with connection and by google assistant. There is a method for work it in offline mode ?? or another assitant that work offline?
