Step #1 - Mount the ProClip center mount, #854013 I was careful mounting it since it just slides between the gaps and grabs the backside of the dash. Had to get a rubber mallet out to make sure it was secure. Once I heard a small "click", it was solid. What I love about this unit is it doesn't require me to drill holes in the dash. Notice the various pre-drilled mounting holes for the various phone clips.
