I have a 2010 Outlander xls with the factory 6 disc cd changer. It has worked fine until the other day. I stopped to get gas and got back in to this problem. Everything works fine as long as the marker lights/headlights are on. If I turn the switch off the clock goes out and the buttons on the stereo do nothing. Sound still comes through but I cant change anything. No memory is lost and the clock keeps the correct time. Any help would be appreciated.
