I just hardwired my radar detector by hooking it up through the fusebox. I saw a metal screw around that area so I assumed it would work as a ground
Please note I am no pro so this may seem like a ridiculous question. I am not positive that the screw i attached the ground wire to is actually a grounded screw.
My radar detector turns on just fine so my question is: Will the detector turn on if it wasnt correctly grounded?
