I have 3800 bought the Sony MEX-BT for two specific applications. As a hands-free system and for streaming audio files via Bluetooth. Both work with my phone (Samsung Galaxy I7500, Android 1.6) easily and well. The connection is established immediately when I come into the vicinity of the radio. There is a brief interruption when starting the engine, but the connection is immediately back. Speakerphone works well, you have to but noisy due to the built-in microphone to talk radio. The built-in USB connector, I use only for charging cell phones.
Criticisms for me are the usual for car stereos confusing control layout and the tactile (also tactile), the blue lighting, which can not be changed in color, as well as a built-in demo function (fortunately be turned off).
Overall, I am satisfied, my main requirement (handsfree) is satisfied, therefore, there is a well of me (4/5 stars).
