Piece of junk, returned it within a week. Downloaded latest DB and then went for a drive deliberately past 3 camera sites (on a 130 mile journey). Missed all 3.
Conclusion on the DB is that it's no good.
also - when it did have a camera in the DB, it goes of within 0.5 mile of the site - i.e from about 30 seconds before the camera and for another 30-40 seconds after. No mute function means that this is a REALLY annoying device.
