Just a friendly pointer!
That's how they think Fabrizio Meoni died in the 2005 Dakar, RIP. Probably hit in the neck by his navigation equipment. I saw the bike and nav tower a little while after he fell and it was not pretty. Keep it as low and flat as you can and minimize sharp edges.
Check out Jonah Street's bike from the last Dakar. He made the navigation tower and fairing himself. It is much lower and further forward than most of the others out there and I think that this makes it safer, more aerodynamic, and easier to read when standing (when your chin should be out over the handlebars.) Nobody said it was pretty, though:
