Volvo Bluetooth® hands-free system accessory
 

I have a 2008 XC70 and a new 2010 V70R. I have grown very attached to the bluetooth capabilities of the V70R and want to add it to my XC70. Volvo have a bluetooth accessory that can be installed in the XC70. Has anyone done it and, if so, do you have any feedback? The capability integrated into my V70R's sound system really works well. I'm assuming the add-on one for XC70 won't be as slick but I have no idea how well it works. Any viewpoints would b helpful.
