I just got my tomtom one and I am trying to set up the bluetooth just so I can answer my phone using the bluetooth. The problem is it is asking for these codes and I don't know where to get it with Centennial. Also I don't want the tomtom to connect to my phone and get on the internet part and make more charges so how does it work just using the the talking part? I have a sony ericson W300i cell phone.
