So I read on here that the Droid uses a magnet to tell if it's in the media dock or the car dock. Decided to try it out myself. I had an old HP holster that I cut a little flat magnet out of and it does work. The funny thing is that the little magnet will stick to the back of the phone so you could use this with any generic car holder that the Droid will fit into. Just stick the magnet to its back and put it in the cradle. Flip it around if you want the media dock page. Kind of surprised me that it stuck on its own. Wasn't expecting that.
