Bluetooth device in a CL9

Hi guys!

Guess I am the proud owner of an 07 limited edition CL9 now :):):):D:D:D

Quick run down on it, graphite grey, 100k, 1 owner, full service history

Been a while since I was last on here, quick noob question:
The car came with this bluetooth device and I forgot to ask the owner about it.
How do I power up the bluetooth device on the dash and can I play music through it?
Any help would be great, thanks guys..
