Is there a back up camera that will work with factory navigation?

Not sure but maybe check that "Go Pro" company?

There are companies out there that make integration modules that allow you to add video and back-up cameras. They run in the area of $350. I have to do some research and post the name of the companies.

Is that for the complete kit? Or just module? $350 seems a tad high?

That's only for the interface module. The camera is extra.

That is something that I would be interested in, some blind spots when backing up that is for sure!
