This iPhone support for GPS use is the best on the market for me, for I am rather disappointed against because the new model has a hole to pass a Lightning cable for recharging, unfortunately I received the old version, which do not have! It was therefore necessary that I drill myself and adapts the hull in order to connect my iPhone on the Moto ... I am a handyman, it took about 30min and 30min study how to do properly, but many people may BE disappointed therefore made attention to the version of the Tigra Sport !!!
If the shell and completely waterproof, even under heavy rain that poses no concern, but it is not submersible! The port to connect the headphone jack is sinking slowly if you submerged by against if he falls in the water and you immediately removed any worries ...
