Is anyone here familiar with the BM83?

I am hoping to get some guidance on integrating it into a car phone project (yes that kind). I will be using microcontroller with BM83 in host mode. peripherals will include a microphone, ear speaker, dial pad, user keys, lcd display (currently controlling lcd with a pico).
The goal is to bluetooth connect to the car phone and use it as regular phone; similar to the ‘Cell 2 Jack’ device function.

I also have the RN52 on hand, but it is quite archaic and there is not much support for it.
