I cannot see e-mail addresses which offer a hint as to where people are located but if you are UK based have you considered PocketGPSWorld where we not only offer a very comprehensive speed camera database and various spoken alerts so the TomTom can actually announce "Warning Gatso ahead, Speed limit is 50 miles per hour"
As David has said you are UK based have a look at
This where you will find a video explaining how to install and configure the database and see/ hear what its like in use.
If you find a camera thats not within the database we also offer a free lifetime membership to the site so membership can become free for those that elect to add locations subject to verification.
I appreciate this isn't what you want to hear having spent hard earned cash on the TT Safety Camera database, but if you want/ need an accurate Speed Camera database then consider how much you value the driving licence or points that get added to it - Mike
