My HTC Trophy is having problems connecting to my Nissan in-car bluetooth connection. Car and phone recognize each other and pair. I can dial the phone from the in-car interface, but when the phone connection is completed I can't hear the other party, and they can't hear me. If I quickly turn the bluetooth off (either on the phone or the car), I can immediately converse with the other party on the call using just the phone in a normal way. So somehow the phone and the car aren't quite communicating properly. I have succesfully paired several different phones with the car over the last 4 years. I just got the HTC Trophy and this was my first bluetooth paring attempt with it. Anyone encounter this previously? Should I exchange the phone or is their a trick I'm overlooking?
