I use a Go5200.
I have used various TomTom's for years and up until the last 6 months or so the speed camera location data (and road work speed restrictions) was excellent. I have noticed recently that the accuracy is far less good than it used to be. Long standing motorway road works speed restrictions and average speed cameras are not going from the device when the road works have been long gone and new speed restrictions and average speed cameras are not appearing when they have been in place for some considerable time.
I am sure my device is updating correctly over wifi - the maps certainly update.
Any ideas anyone?
