Several experiences richer, I went in search for a new Navi, which the United States has pre-installed map. In my research I came relatively quickly to the Z250 from Becker, which is also a very attractive price compared to its competitors.
-very quality workmanship
-Light and stable attachment to the windshield (as opposed to TomTom)
-Very good GPS reception, Satellite be found quickly
-Excellent route guidance and on-screen instructions (especially in split-screen mode), and very good announcements with a clear and distinct voice
-Simple menu control
-no speed-dependent volume control
-Kartenmaterial Not up to date (at least for D)
-voice Tends to rattle, if set too loud
All in all I'm really pleased. The driving instructions are so clear and precise that you almost can not get lost!
The only thing that really bothers me is the lack of a speed-dependent volume control.
That is why a star deduction, otherwise full marks!
In the USA (East Coast), the Navi has done exemplary work. The map was very good, and also the routing was always optimal.
