Recently purchased the RV780 "& Traffic" GPS plus BC30 backup camera. The cam comes with BC30 power cable, which has a built-in receiver for cam vid and for traffic data. I followed the setup, installed the Garmin Drive app for iPhone and paired the phone to the RV780. I don't want the speakerphone features the RV780 intends to provide to the iPhone. I don't need voice commands to the RV780. What I _DO_ want is robust traffic data for the RV780. ?Will the traffic receiver in the power cable provide traffic data without need of pairing the phone to the RV780? I would prefer not pairing the iPhone to the GPS. I prefer the features enabled when the phone auto-pairs to the Mazda car. The real question: what RV780 features are disabled if I don't pair the phone to the RV780? Thanks in advance for your helping me understand these points.
