When parking the car and putting the car in reverse, the cameras are activated and two views are displayed simultaneously on the head unit: 1) a 360 view is displayed; and 2) rear camera view is displayed. However when putting the car in Drive and then back in Reverse again, only the 360 view displays but NOT the Rear view camera. Subsequently drive / reverse sequences during a parking maneuver do not cause the rear camera to display again, The only way to turn the rear camera back on is to keep the car in reverse and then fiddle with the head unit to tap the appropriate button sequences to turn the rear camera back on. This is not safe.
