So I read on another Tundra forum that if you have the back up camera you can shift the tranny into R while driving and it will turn on the rear camera. Has anyone tried this? Supposedly Toyota has done this so you can check on whatever you're towing while going down the road. This also turns on the reverse lights and freaks people out!? I have the rear camera but haven't tried this, you would think it would mess up the tranny.
