You don’t need to buy a new car to enjoy the benefits of a backup camera; you just need $77 (with promo code CI2XBKF8), and a few minutes to run the wires. This model attaches to your license plate, and runs to a special rear view mirror that attaches in front of your existing mirror.
Oh, about that mirror...it has a dash cam built into it too! Just pop in a microSD card, and you have a backup camera, plus a dual-lens dash cam to record any accidents.
