Well its installed and I've done 3 flights with it now:-
I have to say I dont find it cluttered at all however if it were mounted lower down or off-centre I can see it would be.
Very impressed so far and no matter how much abuse I've thrown at it (a lot!) I cant get it to topple or stop working.
As I expected its too distracting to leave it switched on during finals so I simply switch it off on the downwind to avoid being drawn to the GPS derrived speed, fantastic bit of kit for en route however.....
