It did'nt work for me, the Touratech cradle is too tall and not far enough away from the BMW mount and it fouls the inside of the screen. If your not tall you might get away with it by having the mount upright almost parallel to the screen, but no good for me. I ended up with one of the Alder Enterprise mounts (£50 off Ebay) which brings the cradle far enough away from the screen to be angled back and the Touratech cradle fits nicely on that. The Alder mount fits very close to the inside of the screen, but doesn't touch, say about 2-3mm clearance. I have this set up now with a Ztechnik touring (tall) screen and it works for me and my 550.
