Your really should provide pictures of your MCU and used firmware.
Just guessing makes no sense.

Sorry to say, but I think you will only be able to connect phones and OBD on your device, even if you would be able to root it. The implemented BT-stack is not able to do it.

Ok.. i wish to connect TPMS as well.

Kindly help me to crack this..

Can we change the new os on this? I mean new android 11 version.

Please guide me to root it and help to read developers option too. I am not able to see the developers option anywhere as they hide it.

I am not able to help you with this unit.
You will not be able to switch any other firmware on it and there are some devices in the wild where the dev options are even not available.

You can try to push the firmware entry 7 times and may be you will get access to it. It´s often just hidden.

At least it seems that you bought the wrong unit for your requirements... I would prefer something like a Teyes CC3 as mentioned in this thread: https://forum.xda-developers.com/t/teyes-cc3.4189041/

These units are really better to root, there is an easy way to get updates, you woould be enabled to use other BT units as phone and OBD...
Yes they are not that cheap as may be yours, but you get what you payed for.
