I have a wireless backup cam from JC Whitney on my H2. You're supposed to wire it to the hot reverse wire, but I didn't and can turn on the screen and look behind at any time and then just turn it off if the picture is distracting me.. It's nice for keeping an eye on a trailer when I'm towing something. This one installs to the bottom of the license plate and took me 30 minutes to install.
