Just to clarify something about the magnet style car mounts, they don't actually magnetize to the phone itself. You have to put a slim piece of metal in the back of your case for the mount to hold to. I really liked the convenience of just popping my phone on and off, but it caused several problems with my iPhone 5. Because I used a slim fit case, the piece of metal made a bulge, so that the case didn't fit well, and wouldn't lay flat on a table, for example. Because of the small gaps it created, some dirt and dust also got into the case, and eventually scratched the back of my phone. Not good.
I do REALLY like the CD slot design, though, and I recommend that if you don't use your CD player anymore. I finally settled on the one below, which works brilliantly. I can use it with my naked phone or any kind of case, and it holds really solidly. It's also just as easy to get the phone in and out, as I can still do it one-handed. I really love this mount!
