Navigation/Back Up Guidance system for 2003 Honda Civic?

I'm not sure if anyone is familiar with the backup camera for the newer Lexus cars, but there's a camera at the back end of most newer Lexus that turns on when you put the vehicle in reverse and shows you what you re backing up into and also has guidelines to help you show you where your vehicle will end up and also moves around as you turn the steering wheel. If you know what I'm talking about maybe you can help me.

I want to get that (or something similar) into a 2003 Honda Civic LX IF POSSIBLE. Of course I would have to buy a complete aftermarket navigation system which I'm perfectly fine with but I can't seem to find one anywhere.

Could you guys help me find one that would fit in the right car.

There are lots of backup cameras out there on the aftermarket. And you DON'T need a complete navigation system to use them.

A quick search for "backup cameras" found 23,459 results on Amazon.com, and I'm certain there are almost as many on Ebay.
