I have the little box for my father ordered, because he can not see well the speedometer of his car. Two minutes of work and he is stuck with the supplied cradle on the dashboard. Sat-discovery within max. 15 seconds display accuracy properly. The first time, very long charging time, but not as per description in the car, but on standard USB charger, computer course goes. The supplied projection screen is not necessary at all, the device configures the display even in daylight properly in the Frontscheibe.Leider some poor description, but for functions sufficiently. That is why five stars from me. Delivery very fast, well packed!
