I find it a very strange coincidence that the camera would go hey wire at the same time I took it in for a routine service ?. And if the camera was an add on, they should have told that. I have at service done at this dealership (where I bought the car new) and never had a problem. And I did'nt have the car washed, so why unscrew the antenna ?. I still say they done something to cause it and it is aggravating to say the least that now I'm on the hook for it.
