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.

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?
hello to all
i have enable the OBD present on my unit and added to the connector. it is connected by bluetooth (or i should connect by usb)?
altough i cannot pair it i think
is there any procedure to correctly do it?
thanks
It should work with bluetooth but you have to pair it through the OBD app not the Android settings menu.

HI All,
I just installed this unit. ( sorry, will not allow me to post link)
Android9 13.6" Tesla style Car No DVD Player GPS Navigation For Ford Mondeo Fusion MK5 2017+ radio tape recorder multimedia unit
There is a setting for Speed+ Rotation. which does not seem to work, I have tried several possibilities but can't get it to work. I am of the understanding the the OBD Plug is connected to the ECU under the dash. There are only 2 pins on the plug from the Head unit. Is there an additional setting or perhaps i'm missing something.
I have the above head unit fitted and working fine in my car but I have an engine management device that contains a bluetooth low energy module in it. I would like to connect to this module via the provided app however it appears my head unit does not see or connect to BLE devices.
Does anybody know of a USB type device that I can connect to the head unit which will provide the ability to connect to BLE devices?
I'm using standard Dasaita android 10 and 3.69C.
Thanks
I have a similar issue. I have an Axxess signal processor which you make adjustments to it through Bluetooth. The processor connects to my phone but won't even be seen by my head unit (Dasaita max10). These head units only seem to recognize a phone or (select) obd dongles. It's pretty basic. I have been looking for ways to expand this, but so far unsuccessful.
Hi,
I've bought a cheap Allwinner T3 based headunit from Aliexpress and while it does its job, I'm having issues with its bluetooth.
It seems like the bluetooth is controlled only by the dedicated bluetooth app which came with the device. There are no bluetooth options in the system settings, Tasker can't control bluetooth settings (says the device isn't compatible) and bluetooth autoconnect apps say that there is no bluetooth module.
Is there a way to get around that?
What I'm trying to achieve is to make the headunit attempt to connect to 1 phone and if it fails, connect to the other one.
Currently it only tries to connect to the last device which was connected to it and if it fails it just doesn't connect to ANYTHING anymore unless I manually connect it, which is annoying.
me too
Sounds about right.
flash V8.3.2_20180119.100305_TW2-ZHC rom ，There are no bluetooth options in the system settings
After I flashed this V8.3.2_20180119.100305_TW2-ZHC firmware, there is no Bluetooth option!
