The front cover can be completely backwards contact, so you can (for the purpose of navigation) Attach the Iphone also to an ordinary automotive windshield holder.
All connectors, buttons and speakers are cut out and easily accessible.
Now for the downside:
The shell on the back is so thick that when shooting with the flash, the flash light is reflected on the camera cut and the photos are "milky". The darker the environment, the milky, the photos.
In and of itself as a shame the Iphone can do really crisp photos and this leather case would otherwise have been exactly what I, and presumably. many other Iphone owner, sought (n).
I then in my despair about the bad pictures the camera cutout on Case markedly enlarged with a router - without success.
