The backup camera in my 2010 Tacoma is embedded in to the backup mirror. The usability is nearly perfect because it's right next to where you were looking already and is tremendously useful.
I recently rented a u-haul that had this and couldn't believe all cars don't do this. It is very useful having the camera and the mirror viewable at the same exact time.
My 2010 Honda has the same. So much better than putting it on a console screen
