Blue tooth range issue
 

My wife pulled in the driveway the other night talking on her cell, while in one of our other cars. My daughter was in the RS4 getting ready to pull of the garage when the blue tooth connected. She became part of the conference call my wife was having. Is there anyway keep this from happening other than turning the blue tooth on/off each time you need it?

could only happen if the bluetooth was syncd with that phone
 

so take the sync off
