My 09 X5 has both rear camera and pdc.

anyone experience slowness of the camera coming on? When i start my car, and put in reverse, most of the time, camera did not even come on.. until I am almost done with my backup... which made it kinda ureless.. and some times PDC does the same.

also, put in drive.. and the camera would stay on for so long that is very unpleasant.
