Review on GENTEX GENK40A Auto Dimming Rear View Mirror: Enhance Your Driving Visibility by Joe Kokenge

This is an amazing mirror! No more garage door openers dangling from your visor, no more blinding headlights in the rear. It was easy to install and had almost everything you need. I used two additional devices and went straight to the fuse box. My fuse panel uses ATM fuses so I had to buy two five amp ATM fuses and use some plastic zip ties but that's about it. I highly recommend this product and am not afraid to install. It only took me an hour and it was from the moment I started pulling the skin to the opening and closing of the garage door.
