I use a ram mount with the ball on the LOWER bolt hole on the handle bars. USE THE LOWER BOLT!!! I made a mistake and used the upper bolt and squished the wire underneath that I didn't see and shorted out my bike. Use the lower hole!

They are ridiculously overpriced in my opinion, but they work very well. I tried several others and ended up with the ram. So...save the money that I threw away on cheap others and go ram from the start.
