Why can't I get a phone audio from Bluetooth connection to car radio?

[AC Question]

Can't get phone audio from bluetooth connection to car radio

I can pair my BSR Bluetooth with my Samsung S4 mini and my 2007 Mazda 3.
I can answer on the Bluetooth but the audio is still coming from the phone and not the radio.

Re: Can't get phone audio from bluetooth connection to car radio

Welcome to Android Central! What kind of Bluetooth device is the BSR? Is it a Bluetooth car kit?

Go to Settings>Bluetooth, select the settings icon next to the BSR device, and make sure Phone Audio is checked on.
