If you tap the home link button while on reverse, the camera disappears, only to be replaced by the Car Menu, where the home link screen asks you to press again, and only then does it activate. Does it activate for you automatically from the screen showing the backup camera while in reverse???Buckle up your seatbelt. Put car in reverse. Tap the new big homelink button on the bottom left of the screen, not the garage icon on top of screen.
