So, I have a Lexus and am a prior user of the Verizon 8830. The phone worked great, however, I like the form factor of the Curve way better. One problem, when calling from the Curve using my car as the BT headset, the phone doesn't give me audio until the party I am calling answers????? My 8830 did not do this. The 8300 just says calling and then it goes to connected after the party answers. It does not do this when using as a stand alone phone
