Would have been much better if on the VW website where you used to be able to construct your speed cam packages, if you could have add a .wav file to each camera set that rather than the annoying "bong", could have said something like "Warning - speed camera ahead".
Like McMaddy said, you are not really missing anything, and TBH if you have the SPECS cameras on like I do (the variable speed cameras on motorways for example), it gets really annoying as it keeps muting the audio every time you approach one. Next time I update the cams, I'll go the Car-Net route and be happy that it doesn't have the annoying bongs.
