This can get tricky, because as I understand it, the wire harness that has the blue LED also has the wiring for everything else in your overhead console (dome lamps, homelink, moonroof)..... and in 2010 bluetooth was made standard while the LED was removed.
Sooooooooooooo......
The harness for 2008-09 models will have an LED wire but no bluetooth speaker. The harness for 2010-12 models will have bluetooth speaker but no LED. Seems to me you'd have to get the harness for the 08-09 and then pull off the LED wire from the harness, then put it in as one singular wire through your driver's a pillar and then into wherever you can find a connection off your headlamp circuit.
I may be wrong on that, but if you get it to work, however you do, let us know. I'd like to be able to add factory bluetooth to my non-navi 09. Lord knows I KNEW they'd make it standard on non-navi premium sound models for 2010 simply because I saw the bluetooth symbol in the LCD of my HVAC/stereo display center. So the car was originally engineered with bluetooth in mind from the beginning, it's just missing the transceiver and microphone.
