I bought an HTC Thunderbolt car dock and modified it for use with the Sensation 4G. I use a TPU case, so I wanted to also be able to use the car dock without having to remove my TPU case. After about 30 minutes ith a dremel tool, I was able to make it work. It fits very snug, yet goes into the charging port with ease. I am very happy with it. It holds my Sensation great, has good swivel function, and automatically launches the car dock app. I will attach some photos showing what I did. Enjoy.
