I'm looking for the best way to mount my Galaxy S4 as a navigator. Options I'm looking at include the Ram Aqua Box and mount and the Otterbox Defender. Looks like the Defender clip could be altered to attach a Ram ball. Any experience or suggestions, either these 2 options, or any others? Looks like the Otterbox offers the option of plugging it in while in the case (would no longer be WP of course)...does the Aquabox?
