On cold mornings my Sync 3 will occasionally not turn on. I can get the radio to play if I left it on the night before but otherwise I cannot access any radio, Bluetooth, apps, or navigation until the car has warmed up more (usually after work). When this happens the backup camera will stay on even after I have switched to Drive. Has anybody else had this issue? Is it something that a master reset might fix or do I need to take it in?
