I received the Kensington LiquidAUX today as I wanted something for my iPhone 3G that would simultaneously charge and provide an auxiliary out cord in one unit so I only have to plug in one cord. The LiquidAUX is great. It comes with a wireless remote that mounts to the steering wheel and is a very nice addition. The music sounds great, as the audio is sent over the special dock connector cable and utilizes the line out mechanism. I have heard some people have had problems with "whirring" noises when accelerating but I haven't had to drive anywhere yet. I'll post back with my experiences with that issue after I take it for a spin. The set up in my car looks a lot cleaner now than it did before. I have coupled the LiquidAUX with a ProClip mount and I'm really liking the combination. It doesn't do hands-free calling, but I find with the windows closed the speakerphone works fine. I might look into a Bluetooth headset just for the car...but it seems even the average ones are quite pricey. I was able to get it for $49 + shipping off of Amazon (it is $80 from the Apple Online Store). Here are some pictures of the ProClip + LiquidAUX installation.
