I have the RAB alarm permanently disabled via the main menu so I only have to press (and hold & hold & hold) the RAB to shut that off and have had at least two different result maneuvering my trailer:1. RAB is grayed out but returns when I come out of reverse 2. RAB stays off as I maneuver back and forth with a red RAB off light on the main inst. panel. When you shut down and restart RAB resets.
