Today I had some time off.
Since the F658`s windprotection is nearly as bad, as german winters, I decided to copy your idea. Hope you don't mind - but now it's to late to ask anyway
I tried to get the orinial's screen contours (-> the funny looking lines in the center of the screen -> they WILL look better, once finished). Later I want to fit a clear windscreen, which shall be extendable.
Still, I haven't finishe my work yet. Have to do much other stuff, too.
