After searching these forums for a car mount solution, I think I am going to go with ProClip. Seems to get good feedback here, and I like this solution more than a suction cup to my windshield. I had a couple questions that I was hoping other users could give me a quick answer to. 1. One of the clip options for my truck appears to be a single clip that goes in a gap on dash board (link below). It does come with a warning that should only be used with light devices... Should I be concerned about the stability, or will this still be plenty stabile? http://www.proclipusa.com/?sectionpath=383&pageid=14560&processor=content&pcategoryid=12945&categoryid=12960&year=2011&lightwindow=true&usermode=_dualselect&v_pcat=12945&v_cat=12960&year=2011&d_pcat=13759&d_cat=18357&have_holder=false&have_mount=false&p_pageid=1&dtype= 2. What exactly is the "Passthrough" port on the iPhone holder for? At first I thought it was required to charge it, but the holder that does not have the "passthrough" has an opening on the bottom that I assume would allow me to plug in my charging cable (link below). http://www.proclipusa.com/?sectionpath=383&pageid=15349&processor=content&pcategoryid=13759&categoryid=18357&lightwindow=true&usermode=_dualselect&v_pcat=&v_cat=&year=&d_pcat=13759&d_cat=18357&have_holder=&have_mount=&p_pageid=1&dtype= I've sent an email to ProClip as well, but I figured I might get a faster response here. Thanks in advance.
