|
|
I July I set up my Tom Tom with PocketGPS speed camera warnings and there was a very useful table of what distance to set for what speed to get a set time (- eg what distance for a20mph camera to get a 20 second warning). That Sat Nav was stolen and I'm setting up my new one but cannot find the table anywhere - where is it? |

Even easier than that.... You'll notice the figures in the 20 second warning column equates to roughly 10 yards for each mile/hour.
So you can just use 200 yards for 20mph, 300 yards for 30, 400 yards for 40 etc.
Double the above figures for mobile sites. |

Thanks.
What would you recommend as a distance for red light cameras? (given that I would be planning to stop anyway - but it's helpful to know which ones to be very careful about not going on amber etc) |

Thanks for the Advice
PS love the voice warnings - so much easier to know the limit etc and know what it's about with clear voices (I use Nick) than beeps and bells and whistles |
