Mine is a Skorpio Mount, aka my own homemade mount. Which is basically what you asked. I took an iPhone cable, made my own dock, sandwiched it between the seams of the dash ala Pro Clips. Only 4" of cable is visible, the rest is tucked away between the dash and lower panels. Charges and everything is within my fingertips and view such as Google Maps or the internet and my personal assistant, Siri, is at my beckon call.
Hey, would you be willing to snap a pic of the mount setup itself? So far your setup is the one I like the best. I just got a CX-5 yesterday and am looking at the mounting options. I had just put a proclip combined with the rokform mount in my Escape, and it was setup perfect. I'm a little less enthusiastic toward the pro-clip mount that covers the vent at this point.
