End of Average Speed Zone

How does any Sat Nav know it has exited an average speed zone?
It can't be first camera turns it on and second turns it off because we have series of cameras in a row.
I then thought it might be a different camera type, I use iGO text files that have "4" as the average camera type but I don't see a start or finish option. Unless it needs to have a opposite direction setting.
I ask because my Mazda often gets stuck in the mistaken state of telling me to slow down when there either wasn't an average zone or we have passed the end.

Subscribe and get our CamerAlert speed camera warnings. We mark the last camera in a series and end our calculations/warnings.

This is the second similar post in the last few days about the way iGo handles average camera zones.

From what I've read iGo just treats cameras in pairs so cam A turns it on and cam B turns it off, then C D, E F, etc.

Therefore iGo thinks there is no average trap between B and C, D and E, and so on.

It's an iGo issue as they are only expecting an A and B camera. We report every single camera because you may enter the zone at camera B, or C.

As a non-iGo user I dont have an answer but is it possible to add a non-existent "end camera" locally on the sat nav just to keep everything in pairs.?

i.e.
In real life and in the PgpsW database you drive into a Spec zone
Camera A = start
Cameras C, E & G = Intermediate cameras
Camera H = end.

Is it possible to manually add fictitious "END" cameras on the iGo satnav at positions B, D, & F so that real life intermediate cameras C, E & G are treated as start cameras?

I know that this shall not give an accurate record of speed throughout the zone but if it is possible and so long as you dont exceed the speed in any pairing, you shall be safe.

That sounds like two interesting exercises.

1. How does the satnav know there's a C? How does it know there's a series? All it sees is a camera type Average so it start calculating average speed. It finds another camera type Average and that (being overload) triggers a Stop. It doesn't know about the next camera until it gets there.

2. How does the manual Fourth Dan iGo bloke scan a text listing and decide this is a series?

That's just me thinking out loud. A solution doesn't do anything for me - I'm a fanboy (without a blushicon Embarassed

)

I dont know either Dennis. It was a rather loud Brain Dump based on what I would try if it were me.
If it works, it works. If it dosnt, I dont know.

I agree with Dennis that it does sound an interesting exercise.

If you want to mimic the abilities of CamerAlert then don't forget that there are four types of camera in the CamerAlert database: Start; Middle; End; and Exit. Exit is a pseudo End camera type that is used to tell Cameralert to switch off average speed calculation when you leave an average speed zone on a (slip) road that doesn't have an End SPECS camera.

Does the latest version of iGo (for iPhone) handle third party POIs?

Are you aware of anybody who does actually hack the iGo software?

Yes, me. I have hacked iGO 8 and early versions of Primo Ui and speedcam handling but can't get my head around (and can't be bothered) with the Later Primo offerings.
