The temporary restriction is shown in the SLI.

    You probably missed the bit from my earlier reply i've highlighted above. The AU school zone warnings are certainly firmware based and read from the map. It's quite comprehensive in that it alerts before the zone and changes the posted Speed Limit in the SLI to the temporary lower school zone restriction while the vehicle is within the zone, and only at the correct time of day on school days as posted on the official road signs. e.g. 7am to 9am and 2.00pm to 4.00pm. The time is taken from the unit's set time, and the alerts aren't given outside of the posted times when the SLI remains at the usual posted limit. In simulation or when actually driving it's possible to manually set the time and 'trick' the unit into alerting when it encounters a school zone. I have found in practice that it's not perfect though because sometime a zone doesn't alert as expected.

    These are screenshots from a simulation with the time changed to before 9am for a school zone on Ferntree Gully Road not far from Princes Highway:

    BtCBrRL

    spvJyMZ

    FYSSfF7

    6xxXD1s

    6TkRL1G

    dofWEiM

    Note the SLI changes to 40kph from 70kph when the school zones is reached and then returns to 70kph after.

    I've checked Cyclops alert for US but did not find any evident of school-zone (shame because it's a useful alert) We know that Cyclops AU doesn't have it and you show that Cyclops UK claimed to have it. Can someone in UK verified that school-zone does exist in Cyclops?
    I have both current UK maps and Cyclops. If no one else responds, i'll load up to a 3590 or 3597 and try in simulation soon. First map only as an initial test which should be negative and then with cyclops on board.

    Ah ok, I now know what "SLI" is. It's the number inside the red circle, LOL! Sorry I don't use Garmin that much (my Nuvi 760 is on loan to my brother) I guess that's one way to tell Cyclops alert from the map ones. Yes, it is nice that alert is sensitive to time of day; although I think it would be better to post speed limit BEFORE you entered the zone (like Cyclops does) Cops in my area are very keen on catching people going over a couple of miles as soon as you cross the sign (which sometimes does NOT flash to indicate that zone is active) I always hated going across one because I have to hit the brake and try to read the damn sign for time of day when it's enforced...*sigh* Thanks for the snapshots by the way, it's much better looking than my Nuvi

    LOL! Your [laugh, chuckle, chortle] 760 is on loan to your brother? No wuccas Mate. So as not to offend your delicate yank sensibilities, you want i should use something equally ancient or older to do further testing? I have an assortment of 3x0, 6x0 etc in the parts drawer in various stages of disassembly, i'm sure i could put something together which functions, or i can wrestle my 760 back off the dog, it's too heavy to use as a frisbee anyway.

    Interesting that the map embedded AU alerts display on the 3597 in orange, not in red as they do on my 3590 in AU. For the cyclops based alerts, on the 3x97 depicted on the UK site and in your image [Only registered and activated users can see links. ] which it seems is on S. Ridgeview Rd Olathe KS, and i guess you got it from the US Cyclops site. It's showing the same image as the UK site with the red banner giving the upcoming SL [25mph]:

    school zone screen

    So i guess if you haven't been able to isolate the school zone warnings in US cyclops, it maybe not any easier in the UK files if they are the same structure?

    I had a fight with my brother, so I loan him the Nuvi 760, bahahaha! Not only that it's "heavy" but the battery is shot (so it need to be plugged into that stupid large ass dongle to use) No really, I don't use the "ancient" Nuvi 760 that much. I like my cheap 3.5" WinCE running Primo much much better. I'm interested in extracting school-zones because I've heard (via Cyclops ads) and other mentioned it and I really want it for Primo I do not know if Primo support school-zone alert with time of day (the only school-zones for Primo is from *.spc file included with AU,NZ data) Currently no one has been able to decode *.spc files.

    Decoding Cyclops data is different from finding it available for decoding. So far I see no evidence of it under Cyclops US. Now if other countries (like UK, AU, etc...) has it and I can traced the lat/lon from it (as verified by someone via running simulator or for real) I can start the process of decoding it. I'm sure if Cyclops support time of day, it would be a bitch to figure out how to decode it. But that's a different problem.

    BTW, I tried to search for all Cyclops alerts in the S. Ridgeview Rd Olathe KS area (shown in the Cyclops screenshot) and no school-zone show up. So this lead me to believe that either 1) screenshot was made up and there are no Cyclops school-zone in US or 2) it was removed after that snapshot was done.

    Each Cyclops alert/record has certain format which the basics such as lat/lon, type, speed has already been decoded. There are other data area in the record which are unknown/perplexed to me (for example, redlight has a lot of data which doesn't make sense...what else do you need to store for a redlight?) So if a school-zone is at a certain lat/lon, I can extract that lat/lon within plus/minus delta and analyzed it. So if Cyclops US doesn't have it and UK does, extracting it from UK via lat/lon is simple.

    OK, so you're still talking to me, that's a good sign (who said yanks don't have a good sense of humour [emm, sorry...humor], not me).

    Bear with me Mate, i'll load up the 3597 with UK asap then report with some results.

    Neil is (again) right!!!
    Regional Here employees input in Here maps database, the locations of the "school crossing" street signs near a school and encode these signs as "school zones" (but this is not done for all the roads categories).
    So Garmin has access to this information, but I don't Know how they implement this in their maps or even if they have created Cyclops cameras using those coordinates.

    Garmin GPI format does have time of day record (and a very precise one at that)...They also have alert circles and bearings which they could use to implement school-zone alerts. I hope they do this in near future. But having it part of map will prevent any future hacked of it.

    @osiris4isis
    I'm having to have to report that all my 'remote testing' for UK school zones has failed. Setting the GPS time manually to an 'artificial' London time pre-school/after school with UK set as Locale failed to give any alerts for school zones using just maps. So then loaded UK Cyclops loaded and still no joy, got red light and speed warning, but no specific school zones. Maybe need for someone actually on the ground to do live testing, or at least to have had a sat lock in the selected locale maybe. Sorry.

    Thanks Neil, I know tracking down the elusive Cyclops school zone alerts would be hard. Sorry to hear that simulation mode didn't work. Definitely need someone in UK (or anywhere else) to verified it's presence. Until then I'm pretty sure Cyclops doesn't have school zones alerts regardless of their claims, LOL.
