There is an updated version of this product available: WRL-12849
Description: The RN-52 Bluetooth from Roving Networks is an audio module that makes it simple for you to create a hands free audio system for your car or remote control your media center. With this breakout board we’ve made it easy for you to drop it into any project you could use it for. All pertinent headers are broken out and labeled for your convenience.
The RN-52 module combines a class 2 Bluetooth radio with an embedded digital signal processor (DSP). The module is programmed and controlled with a simple ASCII command language. It provides a UART interface, several user programmable I/O pins, stereo speaker outputs, microphone inputs, and a USB port.
Note: There is a silkscreen error on this version of the breakout. The PCM ports are mislabeled and are backwards. This will be corrected in the next revision.

I have only done basic bluetooth audio speaker with this (in connection with android and ios). Connects flawlessly! Sounds pretty good. I did need to put in an amp to drive my 4ohm speakers but that was expected.
I have not gotten my MSP430 chip talking to it yet to send commands such as Renaming the device or auto shutoff but that is probably my code versus this chip. The next step is to get that working, then playing around with an addition of an audio codec!!!
