Sat Nav Mounting

I have a Sat Nav from my previous BMW GS that I'm thinking to put on the GP.
It has a mounting base that needs 12V of course & securing to something. I am considering mounting directly to the Headset Top, over the headlight for ease of use. Of course that means I will have an 8mm diameter hole to carefully drill, but I really do not want it on the right side mirror mount for balance reasons.
What are the preferred mounting positions you folks use other than on the mirror mount?
Cheers.
