just removed mine* - got fed up with it restricting turning when I have my Baglux on.
was easy fit, but you'll need to remove all grips/levers/mountings to slide the fittings down the bars.
lot of aggro though' just for a satnav - why not just bolt a ram-mount to the screen carrier plate. I've done it on two Stroms & frankly doesn't wobble as much as a pukka bracket, plus puts satnav much higher in you line of vision...
