My new 320X came pre-wired for a Back up Cam. I installed a unit from Rear View Safety and it works great. But when I backed the rig into the storage building and shut off the battery dis-connect, I noticed that the power on indicator on the camera was still ON! I had to pull the Battery cables to get it to shut off. Your cameras could be on too! A call to GD told me "that is how they do it,hard wired to battery", My dealer (as well as friends) say "no way that is normal" and the camera should be rewired into the running lights. Who is right?
