I have a JVC KW-AVX810 head unit with Bluetooth add-on. Before 3.0 the bluetooth worked fine for phone calls. Now since 3.0 update now my audio comes works fine on the head unit. Can play iPod or Pandora or whatever. My biggest complaint is that all the sounds are being sent through bluetooth. So whenever I get in my car it automatically pairs to the JVC unit and if I'm listening to a CD or the Radio and don't have the headunit source set on BT Audio then if I get a text message I won't hear it. Notifications and everything are going over bluetooth. That kinda stinks because unless I disconnect my phone from the JVC Audio part i will not get any notifications for text, mail, etc. because I won't be able to hear them.
