On the Anycarlink, thanks to bosco, via an NZ liberty owner boostin:
It's ok. Not great, not sh!t, just ok. You need to really crank the volume in call, and remember to turn it down again before going back to CD or radio! It's nice and clear, but doesn't always connect to my partners iPhone4. Slightly annoying, but I think that's more to do with the iPhone. It streams music well from my SonyEricsson. Very easy to fit, but was hard to find a spot to tuck the box into that still allowed the iPod lead to pop out into the centre console box.
So good, but not great, but for the money, maybe.
Now I'm gonna track down feedback from an Xcarlink user

Are the Parrot kits self installable? Because the HU will be out any way...
