If anyone is interested in a comprehensive and good value speed (sorry safety) camera database for their satnav try this site - I have used them for best part of 5 years and for less than £20 annual membership you can download as many times as you like, most satnav types are covered.
Database is updated every 2 weeks and as well as info published by local authorities etc. they rely on members to spot and verify cameras and submit the positions - if you spot a new camera you get free lifetime membership.
If you are a logged on member the site remembers the last database you downloaded and suggests that as a first option next time.
