Topp Frisprecheinrichtung

have decided to use this free Prein direction because I would not have anything sticking to the sun visor or on the window.
Installation is as easy as shown and the English manual is easy to understand.
The speakerphone has the same with my phone is connected and the quality of my opinion is very good. (Alllerdings is my first hands-free).
Have this up to a speed to 120km gest most and everything works fine (although my car is quite loud).

Would recommend this only speakerphone.
