Picture within picture on your rear-view mirror
Here's a great idea. Put a rear-view monitor where you normally look when you're backing up your rear-view mirror. Accele's RVM430NBTG replacement mirror acts like an ordinary 10" wide, low-glare rear-view mirror, until you put your vehicle into reverse and activate your rear-view camera. Then a 4.3" video screen comes to life on the right-hand side of the mirror, giving you a much more comprehensive view of what's behind you than the mirror alone.
This mirror also features Bluetooth capabilities with a built-in speaker and external microphone included. After pairing with your cell phone, you can enjoy hands-free conversations while driving. The mirror rings and caller ID shows up on the screen when you receive a call, and you'll find buttons and touchscreen controls for the volume.
