I am in the process of installing my new 700bt. I hooked up a backup cam but cannot get it to work. I believe you have to turn this on in the system settings but when I go to it, the system settings icon is not lit up. I cannot access it. Is there some locking code or something I'm missing? Please help.

Nevermind, I'm a dumbass! Parking Brake. Sorry!
