So I received the ProClip holder for the iPhone4 (w/bumper) today. Installation was straight forward -- took just a few minutes. I like that I can control the "firmness" of the swivel. I decided to mount it on the right side because I felt selfish and didn't want to give up my center vent. My wife is always too cold or too hot so she won't miss that center vent on her side. I was worried about giving up the angle by having it more towards the passenger side, but it adjusts perfectly towards me. I'll have to test it out a bit more and will provide additional feedback after a few days of "real life" driving experience. I also installed a USASpec iPhone adapter. What's cool about this adapter is that it DOES support playlists through my factory NAV-DVD head unit and it costs less than just about most other comparable adapters that I checked out. It works beautifully. I can control the volume as well as playlists through my factory head unit. It supports Direct Mode vs. Hybrid mode, meaning if I want to control the iPhone4 directly, I can. Also, it does charge the iPhone4. Despite what the manual does you do NOT need the extra dock. The manual says so, but it is dated. My iPhone4 charges just fine. What you want to look for is the blue and yellow cable -- if it has that, then that's a pretty good indicator that it will charge the iPhone4. I freakin' love this setup. I tested a few of my audio applications and they work/integrate beautifully with my factory speakers. As previously mentioned, iPod works great (with playlists), I can stream Pandora through my factory audio system, 5-0 Radio, and the Navigon voice plays through my factory system even if I have my iPod or Pandora playing. This is more a feature of the iPhone4, but it does a great job transitioning between Navigon and whatever other audio system I have playing when the Navigon voice kicks in. No choppy in and out -- it gently decreases the volume of the music when Navigon voice comes on and then gently transitions back to the music. Anyways, here are a couple pics. Not the best pics because I took these in my garage in pretty low light. And yes, there are fingerprints everywhere -- that's what happens when you take pics right after an installation.
