hi to all
you can get the current database vershion v2.091 of the safety camera ie (speed cameras) from here

and how to use this software from here
http://pocketgpsworld.com/tomtom-go-poi.php
All you need to do to import them is to copy the .ov2 and .bmp into the map directory on the TomTom GO. In the case of the UK this will be "Great Britain Navigator" . It will be different for other countries.
hope this helps
