After extensive research, I have decided on the Kenwood KDC-BT92SD. I wanted a good radio with speakerphone. It should also support SD cards as media and possibly have a USB port. This may the Kenwood everything! In addition, there's still a (MP3) CD drive an AUX input and Bluetooth audio streaming. In addition to the multiple connection options, the radio sounds good too. Thanks DSP can be set extremely much here. Nevertheless, the operation is simple and good. So for me the "All I need" car radio. Oh, and the only drawback that I've discovered so far: The display reflects very me. Since I will probably soon stick a film on it.
