PROS of Sony MEXBT3900U In-Dash CD Receiver
1) The quality of the hands-free calling is excellent! I can hear the callers very well through my car speakers (volume is loud and easy to hear!). Also, callers can hear me very well without any issues, even while driving at high speeds. Please note, that I use an external microphone Sony XAMC10 External Mic for BT (Black), which I highly recommend purchasing. Please see my review on that external microphone where I have added photos of where I suggest the optimal microphone placement is to get the best quality- i.e. to the left on the visor, which is close to your mouth). I didn't even use the built-in microphone (which is located on the stereo faceplate) because of the published bad reviews about the quality of the built-in microphone. I don't know if some of the issues people are having with hands-free call quality with this car stereo is related to not having an external microphone, or if they have one, whether it is placed in an optimal location.

2) When a phone call comes in, and you're listening to music (even when you're listening to music over Bluetooth via A2DP), the music pauses, and the phone call comes through. When the phone call ends, the music starts right back up. Very smooth.
