The individual functions:
Radio: It can be six stations save in three band frequencies. As far as very good. Unfortunately, the radio reception is extremely poor, so that you can while driving repeatedly loses and the station frequency noise heard. This is usually the case after a short time. At the car and the built-in antenna, it is not because another Radio provides a much better reception here.
Speakerphone: Probably the only good thing about this radio. The microphone is good, confident voice quality.
Bluetooth: Normally I stream music or audio books via Bluetooth to the car radio. Here I also never had been problems, but in this radio to my Android phone refuses to send music to the radio.
All in all, a rather modest product that I will send back. Am extremely unnerved by this device!
