Then better yet two euros more ...

This BT adapter I wanted to include a second phone in the car. The AUX jack into an Audi. Because he brings audio and phone profiles, is very compact and this not too expensive (the Audi original costs 140 EUR), it would actually be ideal. And there was me with this adapter is not possible to establish a connection to a Bluetooth device. For this purpose it provides when connecting to the power supply operating. Not very beneficial if you want to use it firmly in your car. The charging cable is not a standard USB cable. On network side USB standard, on the device side, it is a tiny round plug with about 1 mm diameter. Who laid the cable can forget the adapter. I have now bought a BT audio adapter from B-Speech. Although the can not have a phone profile, for use in the car, he is opposed to this ideal here. Standard USB cable runs, while the battery is charging, reliable operation.
