22.4??? - 26.9 mate :D , although only been getting 24/25 since the colder weather came in.
I went for the Parrott MKi9100 in the end - got the display screen tucked away in the little cubby hole where your sat nav is, usb port etc in the glovebox and yet to decide where to put my little control module - just at the base of the auto gear selector is where I have in mind at the moment.
Works a treat though :D
