I'm looking for a device that will safely mount my iPhone on my car's dashboard, so that I can easily glance at the map when using the navigation feature. Is there any such a device that will prevent my iPhone from being a projectile, or that will itself not become a projectile, in the event of a crash? Ideally something that is compatible with multiple types of phone cases because I currently have a Lifeproof case but it is on its last legs and I will probably need to replace it soon with something cheaper. I have an iPhone 4S. Thanks!
