I swear that I saw a guideline in the back-up camera image displayed in the mirror. Sort of a centerline for hitching up trailers. Problem is that I can't seem to make it happen again. Am I missing something? Or maybe just hallucinating.
Thanks

10/07/12 OK. I'm an idiot! This line appears when sunlight hits the camera at certain angles and can appear at different positions depending on that angle. Just so happened that it was damn near centered the first time I saw it.
