I have installed digital display rear view mirrors in two of our family cars. They clip onto your interior mirror and have a 1080p digital display 10"-11" wide and about the same size and shape as your factory mirror. The distinct advantage to this system is twofold. They come with a forward facing camera included and also record continuously as an option to a micro SD card for future reference. The wire is easy to hide or you can have it professionally installed by a car stereo shop. Both of ours are mounted inside, against the rear window of our SUVs. The area they view through is tiny and swept by our rear wipers so the view, even in the rain is amazing, especially at night. Consider this as an option since most of the ones for around $100 or less also include the reversing activation triggered by the power to the backup lights. I just use mine as a full time rear view mirror. A quick tap on the screen switches to the forward facing camera display.
