I use these for my F06 and my wife's F15. They work amazingly well and have a small footprint. Depending on where you attach the magnet, your phone will block part of the vent and probably the 1-3 preset buttons but I can't see any phone holder that won't block something. The best part is since it's a magnet, you just stick the phone on and pull it off when you leave, no clips.
