I got my car back tonight but when I tried the backup camera, it went blank. I called the SA who took it back in the shop. After 20 mins of waiting he came back with a technician who said that the softwre upgrade by default turned off the camera. He said he turned it back on. But I asked my SA earlier if the Camera was tested and the answer was yes. Obviously, he was lying!!! I tested it and it looks like it was working. When I got home, I played with it moving back and forth. Lo and Behold it went blank again and I was not able to to turn it back on. Off to the dealership again. On my way there, I hit a traffic so I kept testing the camera by shifting the gear to Reverse. I guess, after almost 20 tries, the Camera finally came up so I went back home. So far, I had been switching the PDC button on and off while doing Reverse and it seems to be working now!. I just didnt get to confirm the software version because I was just handed the paperwork without any explanations. JMK BMW in Springfield have such a lousy service!!!

Update Today:
The Camera is still working intermittently!!!! and I can't even get hold of my SA nor his Service Manager. I have been waiting for a call back for more than 3 hours already.
