I had to bend a bit of ally tube to get the best place to angle the holder, could have done with some pipe benders to make a neat job of it but I was in a rush and function over form as they say.

This is the clamp on my home made bit of bracket. The water proof jacket clips on and off so the clamp can stay when you park up and you can put your sat nav in your pocket/bag when you are away from the bike.
As the clamp has a ball joint on it you can move it around to get the best angle. Also, I managed to get it up and under the screen which also helps keep a lot of the rain off and boy did we need it crossing Germany on the way to Austria

I couldn't see my indicators or speedo but the Sat Nav has a speed indicator so that didn't matter. I could see the rev bar and fuel light and that came on way too soon and too often


Timbo sent me a link to where you can get them, I'll dig through my old mails and see if I still have it and post it up.
