Hey guys. My Karma did not come fitted with a reverse camera but when hit the R button I get the blue screen. Meaning It has the latest update so all I need is a camera. I am ordering one today but was curious if anyone knows where exactly the connection is on the rear bumper. I was told all fiskers were pre-wired to the rear bumper. Also, will any after-market camera work? Didn't know if there was a specific connector I need. Thanks for all your help.
