Well I had the camera replaced under warranty yesterday and it's now perfect. No wonky bendy image, perfectly straight... and it may be my imagination but the camera operation seems less noisy too (when it pops out of the badge).
On the downside, my car picked up a door ding while it was in the dealer's forecourt 
Nooo! At least the dealer are sorting it.
Glad the cameras all sorted now. I find mine fairly quiet but have no comparison.
There's some unbelievably careless people about. They just don't care. I was actually sat parked up in my car when a woman in a the obligatory huge 4x4 pulled up and flung the door open and 'wham' straight into my passenger door. She looked at me through the window and sort of just apologetically shrugged her shoulders. Can't tell you how quick I was out of the car and inspecting it. Lucky for her, there was no damage!
