In order to get the magnet to activate my phone (Droid) to car mode instead of dock mode, I had to take off the soft rubbery cover to access the inner magnet and turn it over. Then I replaced the cover and went ahead to place the base magnet to my car. I like that the black, thicker phone magnet is strong but pretty slim. It seems stable enough the hold my phone over driving bumps but I haven't had it for that long. The thinner but larger metal sticker I placed on my ipod so I can navigate my music closer to eye level. Overall, pretty pleased with this purchase since it's easy to use and doesn't obstruct your driving view and it's a good price. Let's just see how it goes long term....
