what is bluetooth on a stereo do?

Basically yes, can also be used to stream in audio from a laptop with a BT dongle etc

Yes mate, allows you to make/receive phone calls in the car without having to touch the phone. In fact the phone can be left in your jacket pocket on the back seat and it'll still work. As mentioned above many allow you to stream mp3s saved on the phone/bluetooth compatible device.

They're quite cool tbh
