Downloaded speed camera data for display on satnavs

System

Waste of time. Used to have them on my Tomtom, lots of false positives, partly due to cameras that weren't there, partly due to the fact it had the wrong data for the speed limit on the stretch of road I was on.

MK1 eyeball and control of the loud pedal has done more to keep me points free over the last 20 odd years and a couple of a million miles than speed camera warning devices.

IMO, easier said than done. I think it is iniquitous that a momentary lapse of concentration, or a momentary distraction on the road, can cause you to miss a speed limit sign and you end up with a fine and penalty points. We are all human. I prefer to be as well “armed” as possible.

In my VW Golf, I even have a speed limiter, which I do use on ordinary roads, and adaptive cruise control, which I do use on motorways, but each of these still relies on me noticing speed limit signs and adjusting the maximum speed that my car can travel at.

When the Mk3 Jazz became available in the UK in September 2015, I test drove one for about an hour. The Mk3 Jazz has a camera that can read road signs but, in that hour, it missed two speed limit signs! At one point, I was in a 30mph limit but the screen was telling me that I was in a 50mph limit! I came to the conclusion that the technology is not perfect and is really no better than the map data in my embedded satnav, which does show the speed limit at my car’s current location. But map data gets out of date over time, so you can’t rely 100% on that either.

If you can't observe basic facts about the road (such as entering a town or village from the country; spacing of street lights; speed limit signs on side roads) and can't look out for obvious signs or repeaters then knowing where speed cameras are is pointless as you don't know whether you would be speeding or not. What you need is an up to date map which shows speed limits so you can pay attention to them

I used the pocketgpsworld ones for years, had no issues with it, but more recently with inbuilt sat navs havent needed it.

If you have speed camera data on any sat nav make sure you delete it if you go to France. They take having that data very seriously over there.

In my experience, some of the factors you mention don’t mean much these days. In the area where I live, there are country roads (i.e. fields on both sides of the road, no street lighting, no pavement on either side of the road, no rows of houses, only the occasional farmhouse, etc.) and yet the speed limit on these roads is 30mph!

Yes, I am aware of the situation in France, and in Switzerland for that matter.

PGPSW database is probably the most accurate and gives likely locations of mobile cameras. The TT one is so way out of date. The PGPSW forums give details of how to install into various devices.

I'm sorry, but what is "TT"?

... Even the AA use it on their paper atlas's which you can buy from £1.99 but only get updated once per year.

Yes, and I have just found out that the AZ road atlases use PGPSW as well.

Does anyone have any experience of using downloaded speed camera data for display on satnav maps?

Has anyone used any of these and can comment on the accuracy of the speed camera information, how well it is kept up-to-date, and the value for money?

I have the PGPSW installed on my Garmin, they do update regularly and whilst I find them really useful for fixed speed cameras in unfamiliar locations, the very nature of mobile cameras mean that just about every bridge on the A34 from Winchester to Oxford triggers an alert, it's similar on most major roads.

No doubt each spot has at some point in time been used to monitor the road below but the constant alerts means I turn the alerts off and just set the cruise control to the limit and accept that the tax collectors have won!

Don't use the mobile cameras then !
