So I have always wanted a car mount for my phones that will work with a case. I dont like the suction to the windsheild unit's, hated the ones that clipped into the vents and really couldnt do the ones that plug in the lighter area (I drive a manual and it would be right in the way).
I discovered this place: Car Mounts & Holders - iPodCarParts.com: iPod Parts And Accessories . I saw the owner post on this forum a few weeks back and shot him a pm asking if he made anything for my car, 2006 WRX. I was shocked when he replied with a detailed picture of a custom mount for my car, and it was universal, AND it worked with phones with cases. I switch phones a lot so this is huge for me.
I ordered the mount and it was to my door within a few buisness days and I just got around to installing it. First off, it mounts behind the dash, bolting to a bolt that holds the radio in place. Its SUPER solid, no bouncing around at all. The install was straight foward and took a whole 15 minutes if you know what your doing. I highly suggest this mount to anybody case or no case.
Here is a picture that I took, it didnt turn out the greatest but you get the idea.
