i use one of these as my car doesn’t have Bluetooth. Works fn great. Has usb port and aux port on it. Plugs into 12v on car

My last one was a little more powerful, would transmit clearly to 3 or 4 cars around me, but i accidently snapped it

Used to set it to the local country station so that i never had to listen to country music when stopped at a light.

But i digress, bought mine at best buy for about 50 cdn
