I still can't make my mind up
I prefer the look of the Parrot and the fact your not limited to an iPhone is a plus (my Mrs has a Blackberry) but on the other hand the Apps are a little limiting and you still have external wires for iPhones etc
The Oxygen O'Car look ugly (in my opinion) although I'm yet to see one fitted to an XF and also like to know if it fits properly (I've read on other forums that people have had to modify their dashes because the iPhone is wider than the stereo, on the plus side it would allow me to use all the Apps on my iPhone including Tom Tom.
I really would like to see one fitted before I finally decide.
