I orignally put mine on the handlebars between the supports with the ball mount.
It died of vibration when kept at constant high revs.
I have now made a soft foam rubber mount atached to the bar over the clocks. Its not finished yet as I have had to modify my TomTom to take power from a car charger.
When its finished I will post piccys. Its not pretty but it is insulated from vibration.
