For those who are "Reverse Challenged".
"Rearview Mirror Rear Observation System (#AOM28MR)
No place to install a CRT or LCD monitor? Our new patented replacement rearview mirror with integrated 2.8" LCD panel is the answer. The small built-in LCD displays clear color images from our color camera (#AOC-100) while still retaining the mirror portion for standard rearview operation. Two selectable modes of operation allow manual LCD on/off control or automatic LCD on/off control wired to 12V reverse light circuit. System automatically comes on when the vehicle is put in reverse. Mounts to crossbeam in vehicle above windshield. Operates on 12V power."
