Interesting speakerphone, Aux input on the Radio imperative

The unit itself is very simple and clear, there are only three edienknöpfe, the main control knob is assigned multiple functions.
In addition to this there is a front and a back button, they are responsible for the indexing of the music.
Yes, the device also serves still as Bluetooth Transmitter, so you can leave his cell phone music or navigation voice running through the car radio.
Imperative for this and also for the general operation of a hands-free but is a Auxanschluss on radio.
The speakerphone is namely not only connected to the cigarette lighter for power connection but also on the radio AUX input.
So who has no AUX input on his radio, will not get far with this speakerphone.

If the device is connected to the cigarette lighter and on AUX input you can connect to the smartphone it via Bluetooth.
This went smoothly for me and the connection is stable.
The best way to the speakerphone attached in hand grasp, without the need to take the eyes off the road because you have to accept the calls with the main button.
The enclosed adhesive Button holds good so far and is still in as a substitute.
Depending on the vehicle, it can be difficult to find the appropriate place for the hands-free system, but should be possible.

Call quality is good and the answer will also work well.
As I said, the place for the unit is crucial.
The volume is sufficient and is regulated normally through the car radio.
When a call, the music turns off.

Although you can still use other functions such Voicedialing (this must of course support this smartphone.
In practice, however, I find this Awkward as something by the multiple use of the main buttons.
That's why I use it only to answer while driving.
Music I hear anyway via the USB port, but this feature is an added value.
