And to confirm - you can use both the headlight grill and headlamp shroud thingy just fine. I stopped by TT today and checked it out, and that's the right they have. The lower beak of the Desierto just barely grazes the shroud, but it didn't require any filing to make it fit ... though I'm assuming the headlight was actually pointing at the proper angle. One could imagine having to bump the headlight down a bit if the Desierto is too big ... and if that's the case, the file will be coming out when mine gets here ...
Also, there seems to be ample space for mounting brackets of various flavors - there are various support struts and plates, any of which could take a screw or three and serve quite nicely as a GPS mounting plate. My Zumo plans to move in there for the winter ...
