iPod Bluetooth

As most new Speakers are mostly Bluetooth compatible and don’t have 3.5mm Auxiliary cable input any more.

I am looking for a Bluetooth adapter, transmitter or cable (if that exists) connector that will be compatible for an iPod Classic to connect to a Speaker or (Bluetooth) in a car

I’ve looked everywhere for an iPod touch 7th generation, but haven’t had much luck. My iPhone is not suitable for the amount of songs that I have on this iPod (and the iPod still works perfectly)

I need some advice on what would be the best solution, I’ve looked everywhere online but I’m not sure what to go with I would love it if someone could recommend something

Thank you
