...car head unit? I have a Sony XAV-64BT car radio. The radio is blue tooth enabled and connects well with my blackberry phone. The radio only picks up that I have a text message, but will not show it or allow me to respond to through the radio. I was wondering if there was an app that I can use for Blackberry that will allow me to see from my phone onto my radio head unit. The instructions for the radio tell me that it won't show text or allow me to respond. I think it would be cool to do this, but not sure if it is possible. Any ideas??
