Purchased the car used (2014 RS) about a month ago. On my way home from work was listening to the radio, stopped went into a store and came out started the car. Radio screen displays 89.1 fm 0.0 om the presets and none of the buttons work no sound and back up camera doesn't work. Tried shutting it off and turning it on no change. Called dealer and told not covered under CPO and out of warranty due to inservice date. Anyone have this issue?
