I'm in the process right at this moment, creating a new dock for my new car. I don't wanna gouge up my air vents so this one is a cup holder dock based on a belkin tune dock for a ipod that I had laying around. I am half done and will post up pictures on tomorrows day. I estimate this dock will cost me $4 in added parts, but $13 in the end because the tune dock actually only cost me $9.
