In short, I get those false warnings quite regularly on motorways. Clearly, my warning should not sound for Specs cameras on the opposite carriageway, but it does for some and not for others. Of about six Gatsos on the M4 approaching London, all are eastbound, but I get a couple of false warnings on my way home westbound. I have my warnings set at a mere 300 yards, so it is mega rare for any far carriageway camera to be within driving range proximity. I think TT has some (weird) combination of route and proximity. I've learned to live with it.
We might overcome it (or might not) by moving every such camera a few feet off the road, but I wouldn't fancy the job and in any case, it would probably jigger up all the many other non-TomTom devices. _________________ Dennis
Hi DaveNN
The Oxford dictionary says…Pootle is to move or travel in a leisurely manner. Er! Are you sure you need speed camera warnings? _________________ Tomtom Go 720.

Close to where I live the A34 runs from Solihull southbound to the M42. On this stretch there are two Gatsos on each side of the road. Under old versions of TomTom, I used to get warned about the 2 southbound cameras, and 1 of the northbound cameras.
My assumption was that this was because it was technically feasible to drive round a roundabout and back up past this northbound camera within the 300 yard limit I had set for such fixed cameras. This could be deemed as being similar to your sudden exit off the motorway example.
Conversely, it was not possible to get to the other northbound camera within the 300 yard limit by means of ordinary roads.
With later versions of TomTom, I now get warned of all four cameras, so it is clear that the proximity range has been increased to gather up all nearby POIs. I suspect (though I haven't found one yet) that it will be possible to find an example of a POI outside the proximity range, but still within the POI warning limit that has been set.
Not sure you've strictly UNDERSTOOD me mate either **
As what I was talking about was "How it isn't but could be", not how it is.
So all the behaviour I describe, is what COULD befall a user, IF it worked the way which it DOESN'T.
That is, TomTom does NOT allow only alerting for Cameras only on Current road.
What you describe is entirely true, and entirely correct - that is how TT does work, but what I was talking about is a problem that could arise, if TomTom DID allow only for alerting of POI's on the actual CURRENT ROAD only.
I was describing a hypothetical situation, and a problem that would arise as a result of it, in response to some people's desires for TomTom to actually work said way.
Hope that helps clear up any confusion, and the CAPS is not shouting, but simply INTONING relevant key words, rest assured.
------------------------------------------------------------
Also... in terms of what you say, again, I don't think you've got it right mate, in terms of your first suspicion (said nicely for sure), in that what you describe has nothing to do with Cameras being ON current Roads, as the point is, TomTom doesn't operate that way.
Cameras are only EVER notified to you by TomTom, based on proximity.
So if it did it on one, but not on another, it's simply because of the Proximity Setting. This can be set by the user, but I am not sure what it is by default.
But in your case, it's likely simply a case that the proximity range, as you say, was different from one device, to the other. Nothing to do with being ON actual roads, as you suspected might be the cause, as TomTom doesntt work on "Current Road Only" alerts mate.

Dennis,
I remember something along those lines whereby a Mathematician was being quoted when asked how they can use Math to explain everything in the universe.
Don't suppose you can recall the quote, article or such can you please?

I may have agreed with you, as I thought this initially as well - However the warning I received for the camera on the opposite side of the road appeared as I was passing the camera (i.e. about 20 yards away as the crow flies) but gave a distance of 300 yards. This distance decreased as I moved away from the camera, and towards the roundabout that I could have used to turn back onto the opposite carriageway.
However, it's all a bit academic now as the proximity alert distance has now been increased, and the above situation no longer occurs for this particular camera.
