The tomtom concerned me yesterday when it suggested in places that the speed limit on the M25 was 50, even though there were no warning signs that this was the case and the variable speed limit signs were not in force. I certainly wasn't going through any roadworks at the time. On one occasion it told me that the speed limit was 50 even though I had just come through some roadworks (speed limit 50) and had gone back up to the national speed limit. I imagine that these warnings must refer to where there used to be roadworks. Is there any way of updating the speed camera database please?
