My problem was that the sound in the car (hands free) was very soft almost inaudable ...... Finally fixed it. Found that the in-call volume on the handset has to be up full and then the sound in the car was fine.

All right, I'll tell you what is wrong with Sony, that'simple: the just don't follow the spec and industry standards.
The car audio connection for the phone (don't mess it with media profiles!) is standardized as HFP: Hands Free Profile.
This essentially suppose an audiocodec called mSBC: an SBC codec with lower sample rate @ 16 kHz (and lower bitrate therefore).
Now, if you will go to the 'developer options' menu, you can find out (and supposedly change) some related options. So, you can find there (and force usage) the SBC codec.
But unfortunately, there is no option for getting 16 kHz sample rate (the lowest possible is 44.1 kHz).
Thus, those devices that strictly follow the standard (or jusl limited in recources) - shall not 'understand' what Sony streams to them.
Bravo, Sony engineers, very professional!

My Bluetooth does not allow the call audio to make or receive calls. But the audio work perfect. I can't set it manually. If I try it select it it will just go off again.
