ya about using this as a rear view mirror . how will you see the rear coming vehicles? is the display is some kind of mirror finish or all time cam on?
The screen is mounted on the center rear view mirror and it is having a reflective coating. since it is having larger area than the factory one, the visibility is comparatively wider.
I never had problems with rear view. It was always better than OEM mirrors.
After using this and when I switched to another car iIfelt some problems for a while. After some time, I got adjusted to it.
