I'm currently trying to modify an old radio by adding a Bluetooth Reciever so that when I turn the radio on I have the option to use Bluetooth or continue listening to the radio. I want to be able to control the volume of the Bluetooth Reciever with the radio volume dial and be able to switch from Bluetooth to radio with the AM/FM dial (possibly cancel out the AM completely) is there any one who has any ideas as to how I could possibly do this?
Here is the radio circuit as well as the Bluetooth reciver with the rechargeable battery.
