My wife and I each have an 8830 with VerizonWireless. We just purchased a new Mercedes that has the bluetooth module. My wife pairs with the bluetooth without any problems and her address book synchs with the head unit. I however keep getting an ERROR message...Uncaught Exception: java.lang.ClassCastException. I know that we have differences on our BB's namely I synch wirelessly with my BES at the office and she synch via wired desktop. I also have some programs that she doesn't have such as Google, gmail, etc. Any suggestions???
