The cams aren't that great to be honest as they only give you a visual display that they are coming up.
Unfortunately its not like the cams on the sat nav units Tom-Tom etc that play a sound so many yards before you approach them!!
Although I'm sure someone on this forum was working on that!!
The database for the PersonalPOIs has in the database structure details about direction and speed for POIs. This indicates that at some point the system may be able to warn you about POIs (such as speed cameras) as you approach them.
At this time there seems to be no indication that this data structure is nothing more than future proofing or indeed that it was created by a third party (Continental - the manufacturers) and most likely is not supported by the VW / VAG firmware.
Also, as others have pointed out, some countries prohibit the use of anything that warns you about speed cameras, so VAG might be a little wary of adding the feature in to their cars!
I'll take another look and see if I get anywhere ....
