In short, the thing is scrap.
Why?
1. Does the radio reception
In city traffic, this problem is not to remember - here Radio stations transmit so much on that one only has to lift a finger to the sky in order to have a good receiving antenna.
But as soon as you drive on the motorway or on country makes sichs noticeable: Again and again rushes the radio while driving uncomfortable. Interestingly, the reception improves fundamentally, once you see the connectors of the hands-free system from the wiring plug. Hardly reinserted ists already over with the pure music listening in the car.
Mind you: in city traffic with a very good reception location, the problem does not occur.
Navigate on the highway, while radio can be heard completely impossible.
Not that now someone comes up with the idea, I would have a problem with the electrical system: This is not the first hands-free system that I use, but mind you the first that interferes with radio reception.
2. intelligibility
Well, if you have ne speakerphone, then one would like to understand what so are his opposite number during a call by itself - especially when one's wife can otherwise have unpleasant side effects.
But the trumpet is here installed as speaker, is not bringing a single clean and undistorted sound over capable. Rather klingts as mums old Japanese (transistor radio) from the 60s. A relaxed phone conversation while driving looks all different.
The sound is so bad that the indications towards Navi are hardly understandable - although my Navi speaks no dialect, but clear and clean High German. Well, since you can not listen to the radio anyway while driving can be a little bit better understanding of the aunt in the navigator and radio (Unless you soaked lack radio reception on CD).
3. Microphone Quality
In short - the speakerphone says free for television advertising: "isch have no microphone". Use is the built-in microphone Vario.
Well ... what will be positive but also struck me .... makes me think .... oh yeah ...
Mechanically, the bracket just fine. Can be adjusted easily and the attachment to the windshield via suction cup is also without any problems. The bracket looks stable and also makes no move to larger vibration while driving. Accidental adjustment of the adjustment is almost impossible due to the interlocking joints.
Even the insertion of the Vario is easy. Clean misses it when plugging in the desired position. Although one has a little energetic reprints so that the electrical Konakt clean comes about - but as you get used to it. I have had there already far hakeligere holders.
Conclusion:
As a holder and charger in the car due to the solid mechanical construction thoroughly recommended.
When speakerphone or even completely unsuitable for navigation. At school we would say: Wrong topic, but well written - 5 - set! Here at Amazon gehts so: not achieved on your own claim - 1 star - no further comment.
