I have a 2011 Dodge Durango. It has the media system which includes Uconncet. I want to use the bluetooth in my Razr to connect to the phone system in the truck. I don't want the phonebook in my phone to sync, load on the trucks system. After it loaded I deleted the file and was able to make and receive calls hands free. Later that day I got to my destination. When I returned to the truck, the media system found my phone and sync'd the phonebook again. How can I not load the phonebook onto the truck?
