Hi There
We have problem in Finland with over 800 speed control cameras in small contry. And I think this is a problem all over Europe and US too.
I thik it is not very difficult to use Jornada or other HPCs as a GPS based camera warning system and it is not illegal.
Look at this:
http://www.adteknik.se/english/activeGPS.htm.
In internet there is lot of pages where you can download positions of these cameras for navigation sofwares
(Navigore TomTom etc.
) but simple warning software for HPCs is missing just like ActiveGPS.
Do anybody have skill to make this kind of software?
Best regards from Finland
