Around Thanksgiving I traded my 2010 Sebring Limited for a 2015 200s. Love the car but it's taking some getting used to. My biggest gripe is the radio. It comes on when you start the car and we can't turn it off. We can mute it but not turn it off. The OM shows the different radio options but doesn't describe their use. Ours has the top end system with nav. Anybody have some insight?
