RAM mount, just go to their website and enter in your device and you are directed to all the mounts that will fit it. Also, with RAM if you want to change to a different device down the road all you need is to replace the actual mount and not the where it attaches to your handlebars.
I've had a few different mounts, but the Rider's Claw is the best looking, and works nice. It's not the most inexpensive, but neither are our bikes, right?
