M42 Cameras not in Single POI File

AlanHo

Yesterday I updated my Nuvi 350 using the single file data base. The variable speed cameras on the M42 are not showing up - other roads seem fine.

I have now downloaded the Speed Zoned file and all is working OK.

Why the difference?

Presuming that for a Nuvi you would be using pocketgps_uk_sc.csv, then, if you still have it, open it in Excel or rename it to pocketgps_uk_sc.txt and open it in Notepad. In my copy, I can find GATSO:3405 & GATSO:11183. Do you have them?
I'm not a Nuvi user, but I seem to remember, from other posts, that you only get a warning as you approach (or exceed?) the limit for the camera. How does this work for variable cameras?

Variable cameras are usually set with a trigger sped of 0 mph so it'll be GATSO:12345@0. They will alert at any speed.

Thanks for the responses.

Unfortunately I deleted the single file from my computer before downloading the speed zoned file today. However - I have downloaded the single file again - opened both files in Excel and can see in both files the following M42 GATSO speed 0 cameras.
3405, 3406, 3466, 3467, 3493, 3501, 11183 and 13150.

Hence the plot thickens because all the cameras are in both data files.

I live just off the M42 and use the road at least twice a day. Yesterday with the single file loaded, I got a 40 mph warning as I proceeded along the M42 as I passed junction 4 - but this is a camera on the main road near the junction and is a regular false alarm. However - none of the M42 cameras came up as a warning.

Today I loaded the speed zoned file and drove along the M42 - I got the normal false alarm at junction 4 and all the GATSO gantries that normally give a warning worked as expected.

Tomorrow I will load the single file in my partner's Garmin 350 and drive along the M42 with both sat navs working to check them side by side.

More anon.

Is the false alamr GATSO:1412@40? If so did you have a route plotted at the time?

The problem is confirmed. I have tried using both our Nuvi 350 sat navs side by side in the car. Both have the latest Garmin firmware and both have identical settings. I did not plot a route - just drove with the sat navs on and displaying the map.

One has the speed camera single file loaded - the other the speed zoned file.

Only the speed zoned file displays warnings about the M42 Gatso cameras. I drove along the M42 this morning passing GATSO cameras 3493, 3501, 3466, 11183, 3405 and 3406 then returned home via junction 4 along the A34 and through Solihull town which took me past speed cameras 1412, 1411, 1410, 697, 1303, 1300, 1301 and 1302 on the urban roads.

(Note - it is camera 1412 which gives a false alarm as you drive past J4 on the motorway)

Both sat navs alarmed at all the cameras - but the sat nav with the single file again ignored those on the M42.

I also noticed that the sat nav with the speed zoned file displays the camera locations on the map as a red circle surrounding the speed - in the case of the variable speed cameras on the M42 an asterisk is shown in a red circle.

On sat nav with the single file the camera locations are shown as a dark grey dot on the sat nav display map - including the cameras on the M42 which do not alarm as you approach them. Hence the speed limit is not displayed.

This is all very odd - and to complete my experiment I updated the sat nav with the single file to the speed zoned file and drove the route again - this time both sat navs behaved identically - alarming at all the M42 and urban cameras - and displaying the speed as described above on the display map.

There is clearly something very strange about using the single file on a Nuvi and it would be wise to warn all Nuvi users about it.

An explanation from someone who knows more about this would be very welcome - I am very puzzled.

Can you tell how the cameras appear on the M25? Say camera 14664, between Junction 9 and 10?

Sorry about the image quality. As you will see the icon is just a grey dot.[/url]

OK. As your unit is newer than mine the "missing icon" could now be a grey dot rather than my black dot.

OK here is GATSO:11183@0 with the icon loaded. This is what you should see.

Here is GATSO:11183@0 with no icon loaded. I suspect this is the old version of the grey blob you see.

At the minute i can think of no reason why this should happen. It must be a specific problem with the Single File database and the Nuvi 350 or the firmware you are using. I don't remember seeing anyone else reporting this.
