Have been asked this several times before. The wired headphone plug in on a radio is not available on any DIN size radio that I know. Now the last few years there have been a lot of interest in STREAMING so why not do it with Bluetooth. You will have to look for a unit that does not just connect to your smart phone. This style of connection allows you to first connect a call and then you here it in your headphones. Streaming is usually related to your Smartphone wireless sending music to your radio.
So to answer your question I don't know of a radio that will allow you to pair a radio to it using wireless just for that.
