Re: Back Up camera
My opinion would be that the camera has always been low resolution. The screens on 2011-2013 are low resolution, which in a way makes the picture more crisp. Using the same low resolution camera with the much higher resolution 8.4" screen in 2014+ results in the camera appearing even lower resolution than it did on the previous screen.
Much like standard definition on a tube TV looks better than on HD TV. There's a certain "blur" that occurs on the lower resolution screens that almost makes it appear higher res than it really is.
