Add BLUETOOTH to an old radio

[JniTech]

Hi,
I want to had bluetooth to my old SHARP CD BA125 radio I get this idea on YouTube . But I have difficulty too understand how. There is his plan. I only want Bluetooth so RCA line in I dont need and for the Input Selector I will use a button. All the stuff I need to find because the link of the video was for US an I am Canadian.

XS3868 Bluetooth Audio Receiver
Adjustable Buck Regulator
Prototype Paper

That all I think I need. My question are where the input of The Buck regulator is connected , how hi connected the bluetooth with the Buck Regulator what is the black thing it not on the plan and my last question is on the video the guy have a Buck Regulator 50 V to 35 V But in the description the link is a Buck Regulator 35 V to 35 V wich one is the good.

Thanks for helping

The way that guy does this is very cumbersome.
You can use one of those gizmos and save yourself a lot of trouble.
It can be powered by the most common USB charger.

It requires you to add a line- in input to your radio.
That isn't complicated,especially if you are willing to do it instead of the tape.
