USB Bluetooth

[Daniiiiiijijiijii]

Guys I have a 2006 Toyota Yaris so the radio and that is pretty old. Now I recently bought a USB bluetooth so I could use my aux cord just until I actually get a new radio system. Now I plug the usb in and connect it to my phone but how exactly does it connect ? Like other cars are simple and have a “AUX” button... this is so annoying I just want to listen to my own music. What Button or whatever am I meant to press in order for the car to listen to my phone -.-  

my radio is exactly like the one in the pic

What happens when you press the right hand big knob repeatedly?  Does it just scroll through bass/treble/bal/fade or is there a usb option there?

have you got a link to the USB bluetooth unit that you have bought?

@alan333 it does he bass and that, but no USB option
