Has anyone installed a head end device that supports Bluetooth and therefore hands-free? There's a few recently on the market and at pretty reasonable prices.

Pioneer has some:

I think JVC also has some and likely we'll see it more and more. Wanted to see if anyone had actually done this with the XF and wondering how the road noise sounds on the listener side of the call.
