I bought the car dock and I do not like it. I wish you could just set the phone in the car dock and have it charge without plugging in the charging cable separately. Would it be possible to use the multimedia dock as a car dock? It seems like the only difference is the polarity of the magnet. Can that easily be reversed (cut out and turned around)? I already have an adapter to plug the USB cable into. 3M makes a great double-sided automobile tape that would hold the dock to the dashboard. Anyone with a multimedia dock willing to try it out and report back?
