You can buy a aftermarket backup camera. The cheaper ones come with a wireless monitor that looks like a gps unit for $50-80 dollars. Then there are better ones that replace the rear view mirror with monitor built into the mirror they go for $100-$200. Here's some on ebay to give you a rough idea of what you can buy.http://www.ebay.com/sch/i.html?_from...tm220880288337
