This cable is ideal to connect my iphone in a Mercedes Aux unequipped bluetooth series (Comand APS NTG2 2007). I can listen to all the music on my iphone speakers of the car with a good quality (which is not the case via bluetooth phone box that is located under the armrest). It also allows for the sound of Coyote information that substitute to the music without additional adjustment and does not interfere with the bluetooth phone box. Charging is ensured by the included USB connector.
