| Posted by klenop3 Why do GPS units have no brain? Why is it that ALL GPS units can not think that if it is in a specific area of the world and that area has speed zones in school zones, say 40km then if it is outside the time for school zones or it is holidays or it is weekends then it 'dissables' the allert/waring. Surely this is simply programing. The GPS knows the exact time, date , location in the world your are...seem simple to me. I use a Garmin Nuvi 660 in my car in Australia, but travel abroad often. |
| Posted by r.meeder3 re: school zones It is not so much a problem of the GPS unit as well a problem for the map builders. I spend some time looking at the detailed navteq maps at the navteq mapreporter and those specific details are not in the map data. In the Netherlands we have quite a few roads which are closed for cars during rush hour to prevent people from taking shortcuts. That data isn't in the map. If this data would be in the map then it is up to Garmin and others to implement it in the software. I agree completely with you that it would be a great addition to GPS units. |
| Posted by mikeman1485 Response I agree the map creator would have had to add that in. Also most electronics are only as smart as their programmer ;-) |

| Posted by mercuryfrost Why do GPS units have no brain? I do wish they were smarter. One of the other problems that I notice is when a major highway runs along a secondary road. Often the GPS will say that the speed limit for the highway is the same as the small secondary road. I expect that they two must be too close to each other for the GPS to understand the difference. The same for School zones on roads next to highways. I get the warning even through the road that I am on is not part of the school zone. I expect with the school zone problem, the POI doesn't actually support "times" As a result the GPS isn't actually being told that this information for this location is only effective during certain times of the day. The GPX format, which is an attempt to standardise the POI format and import/export formats for the various GPS devices out there, doesn't have something in teh spec for an "Active" Time. So it doesn't look like this problem is going to go away anytime soon. |
| Posted by jason.learmonth School Zones Just like speed limit data is now associated with mapping, there is no reason why the various entities (Sensis, NavTeq...) cannot collect data not only where reduced school zones exist but also collect information on whether they are permanent or timed (i.e. 0800-0930 & 1430-1600). And yes, the GPS units correct their time to the atomic clock pretty much so are pretty damn accurate time wise. Hopefully such a feature begins to appear because it's annoying being alerted to something erroneously. |
| Posted by johmazz2006 School zones Can't see the problem. If the GPS beeps at a school zone, look at the sign when you get to it, and correct your speed if it is in force at that time of day, otherwise ignore it. If the beep is bothersome, don't instal the sound file in that directory and all stays quiet. |
