2010RX350

My 2010 RX350 do not have the feature to stream music via Bluetooth wirelessly. I tried the 2013 RX350 with iPhone 4s, it has the ability to pair with the in car audio system via Bluetooth and can change song track using the button on the steering wheel. Is there any Bluetooth music receiver that can plug into the Aux music input so that music can be received by the Receiver.
