Hey, here's a neat little $16 gadget from (where else) Monoprice.

Bluetooth Music Receiver

The Bluetooth Music Receiver connects to the Line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or MP3 player to your home audio system. Enjoy the convenience of having your music source in the palm of your hand and listening to it through your home stereo.


-Connects to Aux input on home audio system
-Bluetooth support for all Bluetooth equipment with A2DP audio streaming
-USB A female port for powering the receiver from any USB power source
-Will work with iPhone OS 4.2.1 or Later
-Compatible with all Bluetooth devices that support media audio, including iPad and iPad 2

Looks like you can power it as a wall-wart or via USB, and it has a 3.5mm stereo minijack output (but includes the cable for stereo RCA).
