Dear forum members, I have recently upgraded my sat nav from a Garmin to a TomTom Start 60. I was most impressed with the Tomtom, but after using it for the first time, I am a bit concerned that I have not set it up correctly. First of all, the first speed camera I approached, there was no warning sound, and secondly further up the road, I noticed I was a few mph above the limit of the road. The sat nav only gave me a warning when I was about 5mph above the limit. Can you change this? Sorry for sounding a complete novice, but I am!!! Mark.
