how can i get Bluetooth for my new shuffle

A Bluetooth Transmitter can add Bluetooth to any device. Plug the Transmitter into the phone-out port of the Shuffle and the Transmitter will broadcast to any Bluetooth receiving device such as a speaker or headset. Transmitters are available from $10 up. Some are quite small, about the size of the Shuffle. The Bluetooth Transmitter will pair with the speaker or headphones. Do not need any screen to pair. As long as the Shuffle, the Transmitter, and the receiving device are all charged, you are good to go at home, in the gym, or in the street. This Transmitter same device can be used to add Bluetooth to any old iPod, etc...actually any device that has a headphone-out port (like a Stereo tuner) will work with the Transmitter.

You can't, the iPod shuffle does not support Bluetooth. How do you want to connect Bluetooth using a device without a screen?
