On my Navigator the back up beeps would get solid if you got too close to anything. It was helpful backing up to the trailer because when they went solid, that's how I knew I was close enough. Of course, that didn't stop me from hitting it; that bumper cover did get some abuse. It was annoying when trying to back up my trailer, though, every time I put it in reverse it'd beep like crazy, as if it thought I forgot I was towing a trailer. Eventually it broke, and I didn't miss it. Never bothered fixing it.
