Auto-Vox M1W Wireless Backup Camera Kit | $63 | Amazon | Promo code VCWASK9Z

You don’t need to buy a new car to enjoy the life-changing benefits of a rear-view camera; you just need $63 and a few minutes to install one yourself (with promo code VCWASK9Z). This model doesn’t even require you to run a wire all the way to the front of your car; a wireless transmitter can just stay in your trunk and beam the picture to the included screen from up to 100M away.
