I have an interesting issue with speedcams and my new-to-me ONE IQ Routes. I was on my first long journey today using the TT on the main trunk route from Gloucestershire to London. There are a number of cameras on the route which came up on the screen on time. However, they all showed a speed of 37 in the window. I finally worked out that this was a conversion of 60KPH into MPH on the road which has a limit of 60MPH:)
I had a check of what seem to be the only settings and I am getting speeds in MPH and distances in miles and yards. Anything I am missing?
