I have looked through and searched the treads plus read the manual and cannot find a solution. We have the NAV system with rear DVD. We have figured out everything except: Is it possible to listen to 2 different FM stations at the same time? We would like to listen to classic rock on FM through the front speakers and the kids want to listen to a pop station through the wireless headphones. Right now they are receiving the same music through the headphones that we are hearing through the front speakers. When they change the station on the back control, it also changes the station on the front main unit and changes our listening. So far we have not been able to find the right combination of buttons to get the desired results. Is this even possible? ???
