View very good, navigation impossible

At first I was very excited. The screen display is really great, day and night mode can inspire. The first damper came when I tried to update the map data, is indeed "lifetime"! It's simply impossible to play the latest map material on the device. In the summer, the first holiday, southern France. The navigation is simply a disaster. The distances never fit and constantly I drive past the turn, must turn and look. After the holiday the same in Holland. It fits rarely advise is attached, a disaster.
Unfortunately, 2 weeks rum, return is no longer possible. I werds sell and re-buy a Navigon that can navigate least.
