To use as a FM transmitter / Handsfree mies

Morjen!
In brief: the unit has solved his service as a FM transmitter in connection with my iPod Nano excellent (CD-like sound)!
But I had to put the iPod to loudest stage because otherwise I had to take the car radio itself loud and it has then rushed! But then on stroking rate 87.6 noiseless traveling in Mecklenburg and Brandenburg! (Ie IPOD loud car radio normally regulate the same noise-free)
But unfortunately I had him but then return post, because if I had my phone (Sony Ericson Walkman Mix) connected to the transmitter came a loud noise through the speakers. This was only marginally better when music was on the phone!
The sound quality of the caller at the Freisprchfunktion was very good but unfortunately this could not understand me! The device has been changed but the problems remained in the new device! I now have the FM transmitter Hama Piccolino.Dieser has an internal battery that allows the transmitter in the house or anywhere else where to use a radio-is ideal for radios where the CD player or tape deck that is defective! (Only the most disadvantage, the but each transmitter is owns that he can only be charged via the cigarette lighter) A built-in speakerphone has this also (but which also does not funzt with my phone! For me also when properly set CD-like sound
