Hi, my speed crossed my mine so i have tested the theory, but no, it's no different. I did wonder if it was as simple as the camera not being active, but not prepared to test that theory.
I have a fully up to date mapping navigation system. However I have found that when I approach a safety camera one of three things happens. 1) as I am actually on the camera the car bleeps as a warning. 2) the car bleeps some distance before the camera thus giving me chance to react. 3) makes no sound at all on some cameras. I have checked this on local cameras and they are all on the map of the car but all react differently as above. Does anyone have any idea why this is.
