very convenient for vacation when we do not know exactly where we are, I am used to on my galaxy s3 Navigon is perfect condition to keep the right position in phone and disable automatic screen rotation otherwise moves all the Time is the only flaw. the ability to charge the phone by rolling is very comfortable. When you have a scala rider duo, for listening to zic is top! the box allows through its touch screen to find what you want in your mobile phone. Only downside, there is no possibility darrêter the phone without removing the case.
