If you are using your Rezound for Hands Free bluetooth profile in your car successfully, I would appreciate it if you would identify the model receiver. I've been disappointed with the Hands Free functionality of my Pioneer DEH-6400BT. The Rezound streams audio consistently to it and even transferred the phone book to the receiver. However, and it seems to be random, the person who I call can not hear me at all. When I am connected the other person usually complains about the call quality. They describe it as static. The ICS update had no impact with this issue. This receiver is otherwise pretty good. It has an auxiliary port, USB port for a flash drive and a CD Player so there are a lot of options. As I said the Bluetooth streaming of music works pretty well too with Pandora or the stock music app although some faint clicking can be heard so it's not perfect either. Thanks in advance for your sharing your model and experiences.
