Hello from France,

I just bought a KC BX-411 Android 6.0 head unit on aliexpress, I found the manufacturer with the name , it is a KC Cartech product www_kccartech_com/eacp_view.asp?id=226 , I’m very happy with it except that I can not pair my OBDLink LX OBD adapter.

No problem with bluetooth to connect a phone and it works, the only problem is for the obd adapter, only one chinese model of a friend is working and it have to be named "OBDII" and have MAC Address (identity card) : AA:BB:CC:11:22:33 , it is the generic chinese typical OBD but the problem is that mine has a different name and obviously another MAC Address and the car radio can't pair it (see video) , It seems that the firmware of the car radio is locked to use only a generic chinese "OBDII" with MAC Address : AA:BB:CC:11:22:33. It has been confirmed by a friend who have a android car radio too with same problem and had to replace the original firmware by a sda developer firmware update to solve the problem.

Do you have a firmware update to upload in the car radio to replace mine to be able to connect any OBD adapter ?

From OBDLink support Forums:
You can try renaming your OBDLink with the command STBTDN.
Once connected, you can issue the command "STBTDN OBD". You will then have to power cycle the unit. Once it powers up the device should now broadcast as "OBD".

You can also try changing the Class of Device with the command STBTCOD.
Once connected, you can issue the command "STBTCOD 200400". You will then have to power cycle the unit.

Hi,

Do you have a link to that or to instructions on how to send the command to the OBDLink LX?

Thanks.

I have the same issue, I found that the issue is with the Bluetooth Module (Chip) itself.
You need to check the Bluetooth Module# manually. If you have bluetooth module RDA 5850SM then you need to go through this process CLICK HERE (Credits @dick-jones )
